H MS 939

Product Enquiry

Teroson MS 939 BK is a gun-grade, one component adhesive/sealant based on silane modified polymer, 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 BK is particularly sag-resistant leading to a high position tack after matching of the parts to be bonded.

Terostat MS 939 BK is free of solvents, isocyanates, silicones and PVC and is odourless. It demonstrates good adhesion without primer to many substrates and is compatible with suitable paint systems. The adhesive/sealant also demonstrates good UV resistance and can therefore be used for interior and exterior applications.
Terostat MS 939 BK 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, tension stress and an unattractive appearance are not observed under these conditions.
Terostat MS 939 BK allows accelerated curing as 2-component material. See separate data sheets Terostat -MS Power & Speed Technologie or Terostat -MS 2K -Technologie.
