Product Details

JOINTFLEX-25 Sealant is one component sealant based on silane modified polymer, which cures by reaction with moisture to a soft elastic product. The skin formation and curing times are dependent on humidity and temperature, and 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. JOINTFLEX-25 is a free of solvents, isocyanate’s, silicone and PVC. It demonstrates good adhesion to many substrates and is compatible with suitable paint systems.
