Abstract

The invention relates to a curable composition comprising addition curable silicone component (A) having a linear siloxane backbone at least one unsaturated, non-activated side group pendant from the Si atom or atoms in the backbone, component (A) having an equivalent weight in the range of about 68 to about 1000, crosslinker component (B) comprising at least 2 SiH groups, catalyst component (C) being able to catalyse the reaction between component (A) and component (B), filler component (D), wherein the equivalent weight is defined as (molecular weight of the molecule)/(number of unsaturations in the molecule).
