Abstract
Coupling agent and primer compositions comprising a conventional silane coupling agent (1), and a disilyl crosslinker compound (II) of the general formula (RO).sub.3 SiR'Si(OR).sub.3 where RO denotes a hydrolyzable group, R' denotes a divalent organic radical, and the weight ratio of (I) to (II) is between 1:99 and 99:1 inclusive.
Claims56
A [comprising] coupling agent and primer mixture consisting essentially of:
- (I) a silane coupling agent;
- [and]
- (II) a disilyl crosslinker compound represented by the general formula
- (RO).sub.3 SiR'Si(OR).sub.3
- wherein RO denotes an alkoxy radical having 1 to 8 carbon atoms, R' is selected from alkylene groups having 1 to 9 carbon atoms, ##STR5## in which x and y are 1 to 5[.] , ##STR6## in which x and y are between 0 and 3 inclusive, or ##STR7## in which s, t, u, and v are 1 to 3 inclusive and wherein the weight ratio of (I) :
- (II) is between 1:99 and 99:1 inclusive ;
- and
- a solvent mutually compatible with said coupling agent (I) and said disilyl crossliner compound (II), whereby said mixture is effective as both a coupling agent and a primer.
