3M™ single-step primer is designed specifically to promote the adhesion of urethane adhesive/sealants to windshields and other automotive glass applications. This one-part primer is ideal for touching up minor pinch weld scratches and can be used to prime encapsulated glass. It is also suitable as a blackout primer to help protect against UV rays. Specifically for use during windshield replacement jobs, our 3M™ single step primer is a one-part primer that promotes adhesion of urethane adhesives to glass. It is very versatile - you can use it for a range of windshield-types including those with pre-applied adhesive (PAAS) systems or PVC/encapsulated glass. This fast drying one part primer requires no activator. It is excellent for corrosion protection when used for minor touch-ups on pinch weld scratches. It also features excellent UV-resistance, making it ideal as a black out primer for protecting urethanes and promoting long-lasting windshield installations. 3M™ single step primer works well with all 3M™ auto glass urethane windshield adhesives and is best applied with a 3M™ urethane primer Dauber PN 08688.
3M 08682 black primer is compatible with glass materials with a 10 min cure time. For use with polyurethane. Comes in a 30 ml Bottle. This primer is packaged 30 ml per inner, 6 per case.

Material Compatibility:
Material compatibility lists which materials the product fills. Acrylic adhesives are suitable for use on a wide range of materials including wood, ceramic, fiberglass, metal, and plastic. Contact adhesive is typically used on wood, drywall, concrete, and vinyl. Methacrylate adhesives are compatible with metal, acrylic, PVC, and gelcoat. In addition to material compatibility, other factors may determine the best type of adhesive for a certain application such as brittleness, flexibility, and the adhesive?s resistance features.
Chemical Base:
Chemical base is the primary substance in the product. Adhesives with methacrylate bases are used in structural bonding applications and work well with tough-to-bond materials. Silicone-based adhesives are extremely flexible and ideal in high-heat environments. Epoxy-based adhesives are available with different resins and hardeners to bond effectively with a broad range of materials.
Cure Time:
Cure time is the length of time it takes for the adhesive to completely dry or harden. Different cure times may determine the best application method of the adhesive. Since most polyurethane adhesives cure quickly, dispensing machines are ideal in these applications. Light curing adhesives require light sources within specific wavelengths to cure where the strength of the light source affects cure time. Depending on the particular adhesive, temperature and humidity greatly increases or decreases the actual cure time. Many acrylic adhesives cure quicker than epoxies.
