ABSTRACT:
Improved compositions for forming pellable films, such as adhesive-release backings, are disclosed which have antistatic characteristics, decreased peeling resistance with respect to adhesives and a more stable peeling efficiency with respect to aging.
The improved compositions of this invention comprise a curable mixture of a vinyl-containing organopolysiloxane, an SiH-containing organopolysiloxane and a metal addition-catalyst which has mixed therewith an alcohol- and/or polyether-modified organopolysiloxane.
This use of an alcohol- and/or polyether-modified organopolysiloxane provides a decreased static charge, less dust attraction, less blocking and better adhesive coating for the cured pellable film.
