TEROSON MS 939

(Known as Terostat MS 939)

Terostat MS 939 is a gun-grade, one-component sealant based on silane modified polymers, which cures by reaction with moisture to an elastic product. The skin formation and curing times are dependent on humidity and temperature, and the curing time also depends on joint depth. By increasing the temperature and moisture these times can be reduced; low temperature as well as low moisture retard the process. Terostat MS 939 is particularly sag-resistant leading to a high position tack after matching of the parts to be bonded. Terostat MS 939 is free of solvents, isocyanates, silicones and PVC. It demonstrates good adhesion to many substrates and is compatible with suitable paint systems. The sealant also demonstrates good UV resistance and can therefore be used for interior and exterior applications. Terostat MS 939 demonstrates the strength necessary for elastic bonding. This property of the product also remains at the temperatures in repair ovens (max. 100°C). Terostat MS 939 shows no shrinkage, and therefore dimpling and tension stress are not observed under these conditions. Terostat MS 939 allows accelerated curing as two-component material.
