Henkel MS939 MS Polymer Adhesive

TEROSON MS 939 is a 1-part, low modulus, flexible, odourless modified silane polymer adhesive used for elastic sealing and cures to an elastomeric thermoset product TEROSON MS 939 is a black, white or grey, 1-part, low modulus, flexible, odourless modified silane polymer adhesive used for elastic sealing. It cures to an elastomeric thermoset product resistant to UV. It is sag-resistant leading to high initial tack. It is non-corrosive and free of solvents, isocyanates, silicones and PVC. The cure speed can be accelerated by using LOCTITE MS 9371B. Teroson MS 939 is a gun-grade, one-component adhesive/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. Teroson MS 939 is particularly sag-resistant leading to a high position tack after matching of the parts to be bonded. Teroson MS 939 is free of solvents, isocyanates, silicones and PVC. It demonstrates good adhesion to many substrates and iscompatible with suitable paint systems. The sealant also demonstrates good UV resistance and can therefore be used for interior and exterior applications. Teroson MS 939 demonstrates the strength necessary for elastic bonding. . Teroson MS 939 allows accelerated curing as two-component material. See separate data sheets Teroson MS Power & Speed Technology or Teroson MS 2c-Technology.
