Abstract
Abstract This invention concerns coating/sealer or impregnant compositions for substrates, for example cementitious substrates the compositions comprising (a) one or more dicyclopentenyl or dicyclopentenyloxy(C 1 -C 4 )alkyl acrylate or methacrylate, and (b) one or more drying oil fatty acid in an amount of at least percent by weight of the total of (a) and (b). Porous, e.g. cementitious, surfaces treated with the compositions of the invention exhibit improved water and crack resistance.

Claim 1
Independent Claim
48 words
A coating, sealer or impregnant composition comprising (a) one or more dicyclopentenyl- or dicyclopentenyl-oxy(C 1 -C 4 )alkyl acrylate or methacrylate monomer, and (b) one or more drying oil fatty acid in an amount of at least 4 percent by weight of the total of (a) and (b).
Claim 2
Dependent Claim
48 words
A coating, sealer or impregnant composition comprising (a) one or more dicyclopentenyl- or dicyclopentenyl-oxy(C 1 -C 4 )alkyl acrylate or methacrylate monomer, and (b) one or more drying oil fatty acid in an amount of at least 4 percent by weight of the total of (a) and (b).
Claim 3
Dependent Claim
37 words

Claim 4
Dependent Claim
21 words
A composition as claimed in claim 2 wherein the dicyclopentenyl-functional monomer is dicyclopentenyloxyethyl methacrylate and the hydroxy-functional monomer is hydroxypropyl methacrylate.
Claim 5
Dependent Claim
70 words
A composition as claimed in any preceding claim additionally comprising a polymerization catalyst consisting of (a) organic peroxide and aromatic amine accelerator, or (b) polyvalent metal salt or complex and organic hydroperoxide, or (c) mixture of (a) and 0.005% to 2% by weight, based on the total weight of monomer, of polyvalent metal salt or complex, or (d) mixture of (a) and (b), or (e) polyvalent metal salt or complex.
Claim 6
Dependent Claim
24 words
A composition as claimed in claim 4 wherein the polymerization catalyst is a polyvalent metal salt or complex and the polyvalent metal is cobalt.
Claim 7
Dependent Claim
16 words
A composition as claimed in any preceding claim wherein the drying oil fatty acid(s) is/are conjugated.
Claim 8
Dependent Claim
56 words
