Abstract
A primer composition containing (A) an organosilicon compound having a fluorine-containing organic group and having hydrogensilyl groups at both the terminals of the molecule and (B) a platinum group metal catalyst, and a method of modifying the surface of silicone rubber by using such a primer composition. This primer composition enables firm adhesion between a silicone rubber and a curable liquid fluorine rubber.
Claims4
A primer composition consisting essentially of (A) an organosilicon compound having a fluorine containing organic group and having a hydrogen silyl group at both of the terminals of the molecule and (B) a platinum group metal catalyst, wherein said organosilicon compound is a compound represented by the general formula (1):
- ##STR5## wherein R represents an alkyl group;
- L represents an integer of 1 to 3;
- Rf represents a divalent fluorine containing organic group;
- R.sup.1 may be the same or different and represents a divalent hydrocarbon group;
- R.sup.2 represents a substituted or unsubstituted monovalent hydrocarbon group;
- and m and n are each an integer of 0 to 2.
