ABSTRACT:
The present invention relates to an organopolysiloxane composition containing a cyclopentenyl radical and crosslinkable in a thin layer by exposure to ultraviolet light, characterized in that it comprises:
A. 100 parts of diorganopolysiloxane containing at least 3 cyclopentenyl radicals per molecule, each of these groups being directly linked, by an SiC bond, to a different silicon atom, and
B. an effective amount of at least one photoinitiator.
Application of the compositions to the production of coatings, especially for the production of non-stick coatings on paper, and for the encapsulation of printed circuits.
