Single component silane-terminated adhesive Single component silane-terminated moisture-cure adhesive. MONOSIL does not contain water, solvents, isocyanates, epoxy or amino compounds or heavy metals (tin) and consequently does not bear any health or risk warnings or symbols. MONOSIL has excellent adhesion characteristics on all subfloors as well as permanent elasticity. These characteristics make it the ideal adhesive for laying engineered and traditional solid wood floors of average size on all subfloors, with or without underfloor heating. MONOSIL does not harm the coating of pre-finished wood floors and for this reason does not leave any marks; other features of this adhesive are the ease with which it can be worked, the high level coverage, resistance to water and the capacity to absorb sound leading to a considerable improvement in the comfort of the environment with regard to noise levels.
