Overview
Bostik® 70-03A SSKF is a high-quality, SMP-based adhesive sealant that offers primerless surface adhesion with a longer open time than the Bostik® 70-03A for extended workability and assembly. Bostik® 70-03A SSKF is formulated with specialty silyl modified polymer technology free of isocyanates, solvents, and PVC and offers robust compatibility with most common substrates and paint systems, including industrial paint and lacquer systems, for ease of use and reliability.
Bostik® 70-03A SSKF is suitable across a wide range of bonding applications, including the making of elastic construction joints and large bonding applications that require high strength and durability. Upon curing, Bostik® 70-03A SSKF exhibits excellent resistance to UV and aging, enhancing the longevity of bonds and increasing the service life of the equipment. Bostik® 70-03A SSKF is extrudable via handgun or air pressure gun within a temperature range of 40°F to 95°F (5°C to 35°C) due to its low viscosity.
