  • Additive for modifying the coefficient of friction of silicone release coatings and having low extractable silicone
    Patent number: 6569914
    Abstract: Low solvent and solvent-free silicone release coatings may be prepared with varying COF levels by incorporating a very high molecular weight, substantially non-reactive organopolysiloxane into a conventional curable release coating. By supplying the COF additive in the form of a relatively low viscosity master batch, adjustment of COF may be made by the coating applicator. Very low COF values can be obtained from tin-free, solvent-free coating systems, while at the same time, the coatings have very low extractables.
    Type: Grant
