Bostik® 70-08A AP is a top-quality, SMP-based, primerless adhesive developed for efficiently bonding materials in automotive manufacturing with exceptional strength.
Bostik® 70-08A AP is an advanced adhesive bonding solution based on a silyl modified polymer (SMP) without solvents, isocyanates, or PVC. Bostik® 70-08A AP offers high-strength adhesion across a wide range of substrates, including glass panels and windscreens, without requiring a primer. Bostik® 70-08A AP also provides excellent UV, weather, and aging resistance for both outdoor and indoor applications.
Bostik® 70-08A AP is a black, odorless adhesive that can be easily extruded with a handgun or air pressure gun. After application, it offers an open time of less than 15 minutes, achieving full cure at a rate of 3 mm of depth after 24 hours. Bostik® 70-08A AP also provides permanent elasticity within temperatures ranging from −40°F to 248°F (−40°C to 120°C) with low volume shrinkage.
