For broad-spectrum primerless adhesion from a multi-purpose product, choose TEROSON® MS 930. This gun-grade, 1-part sealant is based on silane-modified polymer (SMP) and comes in white, grey or black. It cures by reaction with moisture to a soft elastic product. The skin formation and cure times are dependent on humidity and temperature, with the curing time also dependent on joint depth, but you can reduce these times by increasing the temperature and moisture levels. The sealant is free of solvents, isocyanates, silicones and PVC, and you can rely on good adhesion to many substrates as well as compatibility with suitable paint systems. The sealant’s great UV resistance makes it ideal for both interior and exterior applications.
