Bostik STR 60-03 – High-performance, one component sealant adhesive based on Silyl Modified Polymers (SMP)

General Description

Bostik STR 60-03 (ex Simson STR 350) is a high quality elastic bonding adhesive based on Silyl Modified Polymers (SMP). It is suitable for elastic bonding constructions in industrial applications. It has good resistance to UV, weather and temperature, and exhibits good adhesion performance on a wide variety of substrates (minimal or no pre-treatment necessary) it can be overpainted with most common industrial paints.
Bostik STR 60-03 is free from solvents, isocyanates and silicone making it safer for workers and the environment.
