(B) an amine functional silane of the formula,
R NHR Si(R ) (OR )4 3 2 1
13-b
b
1 2
wherein R and R are monovalent hydrocarbon groups of 1
to 4 carbons and b has a value of 0 or 1; R is a divalent3
hydrocarbon group of the formula,
(CH )
2 x
wherein x is an integer of from 3 to 10; and R is4
selected from the group consisting of hydrogen, a monovalent
hydrocarbon group of one to four carbons and a group of the
formula,
R NHR5 3
3 5
wherein R is as defined above and R is hydrogen or a
monovalent hydrocarbon group of 1 to 4 carbons
wherein the ratio of the number of amino groups in the amine
functional silane to the number of epoxy groups in the epoxy
resin is int he range of 1:1 to 5:1;
(C) a catalytic amount of an organometallic compound;
and
(D) an organic solvent
which composition, when added to an OH-terminated
polydiorganosiloxane, then applied to an EPDM-base rubber
surface and cured thereon, forms an abrasion resistant film
adherent to the surface and having good freeze-release
properties.
