H.B. Fuller STP 1921 Modified Silane Sealant is a high-quality, neutral, elastic single-component adhesive/sealant based on silane-terminated polymer, which cures by reaction with moisture to an elastic product. The skin formation and curing time 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 temperatures as well as low moisture retard the process.
