Detailed Instructions for DINITROL Vehicle Glass Replacement

DINITROL urethane products are for professional use only.  Certification is required either from Eftec Aftermarket directly or via an Eftec Aftermarket Certified Gold-Trainer.  Other certification programs approved by Eftec Aftermarket include: Performance Achievement Group (PAG), Auto Glass Technical Institute by the NGA, or Automotive Glass Consultants, Inc.

These instructions are subject to change without notice.  Visit www.eftecna.com for the latest version and always check the revision date in the upper right hand corner with each set of instructions.

Refer to the product Technical Data Sheets (TDS) for additional technical information.  Read all Material Safety Data Sheets (MSDS) for each of the products obtained and to be used.  Follow all safety instructions and recommendations.  By federal law, OSHA requires a MSDS be present or immediately available with each urethane, primer, and activator product.

Instructions published on dinolagr.com take precedence over any other written or published instructions by Eftec Aftermarket.
1.    Read all the instructions listed before starting any phase of the glass installation. Always wear proper safety gear as specified in each MSDS for each product to be used or handled. (Visit www .eftecna.com/msds.html)  This includes and is not limited to: proper fitting and approved safety goggles, nitrile gloves, and specific types of respirators when required due to poor ventilation.
2.  Follow the car manufacturer's instructions for the removal and replacement of the desired glass.  Instructions may specify a certain type of urethane.  Specifications may include high modulus and/or low conductive.  Select the appropriate Dinitrol urethane that meets the specific requirement for the given vehicle, see the technical summary chart in the Dinitrol Vehicle Replacement binder or at www.eftecna.com.  For lower temperature installations consider the following: For cold weather installation at 0°F use D-506.  or  D-9000.
3.    Unless specified by the specific Dinitrol product, the glass replacement should not take place in temperatures that are less than 5°C (40°F). Likewise if the temperature is extremely high >45°C (>115°F) then do the replacement in an air-conditioned shop to moderate environmental conditions.
4.    Make sure the car is securely parked and level. (all 4 wheels on the same plane.) Just before trimming down the original urethane bead, be sure to remove all dust and debris.  Unless specified by the car manufacturer, use the full cut out method cutting the original urethane bead down to approximately 2 millimeters (1/16 inch) attached to the pinchweld.  Do not damage the paint system.  Ensure no adhesion failure at the base of the original urethane bead.  Any sign of adhesion failure of original urethane bead will require removal of existing bead.  Do not replace windshields for vehicles that have rust or corrosion in the pinchweld.  A vehicle that has corrosion in the pinchweld should be restored to factory condition or repaired according to OE instructions. Visit www.eftecna.com/rust.html.
5.    Again ensure all bonding areas are free of dirt, debris, solvents, silicone, butyl tape, or other foreign substances.  Dinitrol urethane is compatible only with OE grade auto glass urethane.
6.    Pre-set the new glass to ensure proper fit.  If the glass will not fit properly do not attempt to make it fit.  Order a new one.  Observe if the glass to be installed has (PAAS) pre-applied urethane system.  If so, D-540 PAAS Reactivator should be used.  If the glass is PVC encapsulated, then D-560 PVC may be required if the urethane is expected to bond to PVC and not to the glass or ceramic frit.  See special instructions for these two activators at the end of these instructions.
7.   Pinchweld Preparation: There are two objectives to consider in determining if the pinchweld needs primer.  First, if the pinchweld has scratches or bare metal then it needs to be protected from corrosion.  Second, if there is not a previously set and cut bead of urethane with which the new urethane is to bond, then the pinchweld surface needs to be prepared and primed before a new fresh Dinitrol urethane is applied.  If the original bead of urethane is firmly in tact after being trimmed down to approximately 2 millimeters then the pinchweld may not need any primer.  On a wider frit band when it may be difficult to determine just where the new urethne will make contact, apply a much wider lane of black primer on glass to better ensure contact with the urethane.  Ensure that no dust or debris remains in the pinchweld bonding area.  Use only pure water as a cleaning agent to remove dust or debris from the bonding surface of the old urethane.
8.    Get pinchweld primer ready.  Use either D-530 or D-528 as pinchweld primer.  Ensure that the steel balls in the primer bottle are free from the settling carbon black at the bottom.  Shake the bottle vigorously until the steel balls have come loose and rattle inside.  Shake for an additional minute to ensure the substances are well mixed.  Ensure that shelf life has not passed including open shelf life.  Always replace primer lids immediately ensuring that the seal is in place.  Keep primer lids closed tight.  Apply pinchweld primer to areas that have been scratched or areas that have small areas of bare metal exposed or areas where there is no remaining urethane in which the new urethane will be in contact. However, avoid getting pinchweld primer or any solvent on the old urethane bead.  Allow the pinchweld primer to dry for 10 minutes.  for rust, corrosion, pinchweld repairs visit www.eftecna.com/rust for specific instructions.  Note:If the vehicle requires body repair work and has to be painted, do not trim the original urethane down to the 2 mm until after it has been painted.  Make sure that the pinchweld or flange is masked off.  If the vehicle does come back with new panel sections including the pinchweld, and is freshly painted, the paint must be dry prior to priming.  D-530 and D-528 might not bond well to clear coat or fresh paint. After the paint system has dried completely, it will only require scuffing with sandpaper or steel wool.  After removing the dust from sanding or scuffing (use pure water to clean off dusting) and after it has dried sufficiently apply D-530 or D-528 to the bonding surface.  If covering larger sections of bare metal, apply a second layer of D-530 or D-528 after 20 minutes of drying.  Then wait an additional 10 minutes for drying before applying primer.  If bonding directly to e-coat, lightly scuff the e-coat prior to applying primer.
9.   Glass Preparation: Clean the entire glass with a thick layer of any industry approved glass cleaner. (i.e.  Pilkington's S50, Spray Away, or Burco.)  Spray on a generous film of the glass cleaner to the entire surface of the glass especially the bonding area of the glass.  Wipe off film with a dry lint free towel.  Repeat the wiping/drying process until clean and dry.  Repeat the cleaning process as  necessary  until all film or residue on the bonding surface of the glass has been removed.  Encapsulated glass units such as DW1217, 1123, 1124 etc. are more likely to have a film on the glass from the manufacturing process that is more difficult to remove.  Agents such as MEK or Acetone may be needed to remove such films.  Both of these agents are available at your local hardware store.  Use only as directed by the manufacturer of the product  and follow all safety recommendations.  In any case, be sure that the glass unit is sufficiently clean on the bonding surface and properly prepared before applying primer.  Eftec Aftermarket does not recommend or approve trans-replacement of used glass. e.g. from wrecking yards, recycled car part sources,etc.  If replacing the original glass in the same vehicle, make sure that the urethane is firmly intact and then trim the urethane down to approximately 2 mm.  If the original urethane on the glass has lost integrity or is not firmly in tact, carefully remove all of the urethane with a razor blade.  Next, use a scotch brite or scrubbing pad with approved glass cleaner and scrub the remaining film of urethane and primer off the glass.  Then wash the entire glass clean and wipe dry.  If the original primer and urethane does not come off the glass completely after this type of process, order a new glass.
10.    With a clean unused dauber wipe on the D-520 to the bonding area.  (D-520 is a required step before applying D-530)  Allow a few seconds for activation/cleaning and wipe it off using a clean, dry, lint free cloth or paper towel.  Wipe D-520 dry before evaporation. (D-520 may be used prior to the use of D-528 to help ensure a cleaner surface and maximum bonding)
11.    Use either D-530 or D-528 1-Step as glass blackout primer.  Shake the bottle vigorously until the steel balls have come loose and rattle inside.  Shake for an additional minute.  Apply blackout primer on the black ceramic frit (or area of glass where the urethane will make contact if no black frit exists).  Use a fresh clean dauber to wipe on a smooth continuous lane of primer on the glass/frit in the same location the urethane bead will make contact.  Always close lid (with its seal in place) tightly after each use.  Allow the DINITROL primer to dry 10 minutes.  If the primer must be applied in temperatures lower than 30°F, allow at least 20 minutes for the D-530 or D-528 to flash or dry down to 0°F and until it is viably flashed and is no longer wet.
12.    Using the DINITROL Hygrometer /Thermometer or other industry approved device, record the current humidty and temperature level.  Also, record all other important information including VIN (vehicle identification number), the date of installation, expiration date and batch number of each primer and urethane used for the given installation.  Keep records accurate, orderly and safe. Eftec Aftermarket recommends using an inspection sheet for record keeping.  Click on the following links to download the inspection sheet: www.eftecna.com/inspectionsheet1 and inspectionsheet2.  A digital photo of preexisting conditions may also prove useful in record keeping of evidence. The expiration date of Dinitrol urethane products may be stamped in DDMMYYformat or written in word form such as April 2003 on each case and cartridge and is batch specific.  In no situation is the date written in MMDDYY format. 

13.    Use the temperature and humidity values obtained and determine the amount of cure time required to meet the drive away time.  Refer to the specific technical data sheet for the product for drive away time chart.
14.   Unless otherwise specified by the manufacturer, apply a triangular bead of the DINITROL urethane to the pre-primed glass or pinchweld equal to the depth of the flange.  Carefully connect all starting and stopping points of bead to avoid leaving any gaps.
15.   Set glass immediately.  If too much time has passed before setting the vehicle glass, the urethane may have already cured on the outer surface and good adhesion will not take place.
16.   Check for leaks using a professional ultrasonic leak detector.  Patch up or correct any detected leaks with a special formulated urethane called D-410. This product is also used as a backfill to help moldings and trims stay in place.  Some moldings require pre-tested primer.
17.  Make sure that the driver and customer of the vehicle for which the windshield has been replaced understands that he/she or anyone else should not drive or ride in the vehicle until such time in which it will meet applicable* federal safety standards.  (To determine these time requirements see drive-away time charts on the specific technical data sheets)   Meeting the appilicable*  FMVSS may not ensure the highest level of safety.  Most urethane products take 24 hours or longer to reach full cure.  Remind the driver and occupants to always properly wear and fasten their seatbelts!
18.   Explain to the driver of the vehicle, that for the next couple of days, the car should not pass through a car wash and ensure that the car is parked on level ground. (all four wheels on the same plane.)
19.    Place the Dinitrol Warning Tag on the steering wheel and inform the customer of the needed down time for his/her safety.  It is also strongly adviseable to get the customer's signature acknowledging the down time and potential risk of death or serious injury if the car is driven and involved in an accident prior to proper curing of the adhesive.

For cold weather installations at 0°F or above use D-506 or D-9000.

INSTRUCTIONS FOR USE OF D-540 PAAS REACTIVATOR:
Sand the bonding area lightly and make sure to remove all dust created by sanding.  Sanding is necessary to remove any remaining releasing agent that may be left on the surface from manufacturing.  Apply a thin film of D-540 PAAS Reactivator o the sanded surface with a clean lint free dauber.  Let dry for 10 minutes.  refer to the technical data sheet for more technical information.
INSTRUCTIONS FOR USE OF D-560 PVC ACTIVATOR:
Some auto glass (typically quater-glass) is PVC encapsulated and must be pretreated with D-560 PVC activator.  Sand the PVC bonding area lightly and make sure to remove all dust created by sanding.  Wipe a thin film of D-560 PVC activator on the surface with a lint free dauber and let dry for 10 minutes.
Note:* According to the ANSI/AGRSS 002-2002, applicable FMVSS for auto glass replacement does not include FMVSS 216 for drive-away time.  FMVSS 216 is the vehicle rollover safety standard.  More than 10,000 fatalities occur each year in the US as a result of vehicle rollovers which may or may not result from a failed vehicle glass or retention system.  Many original equipment manufacturers state in their written instructions additional cure times to reach rollover safety after glass replacement.  Contact the dealership for the vehicle in question to obtain these written instructions.  All up to date OE glass replacement instructions take precedence over instructions written by Dinol.
