Document Type and Number:
Japanese Patent JP6146543
Kind Code:
B2
Abstract:
A surface-treating agent for vulcanized rubber, comprising 10 to 160 parts by weight of a wax having a softening point of 40 to 160°C and 10 to 160 parts by weight of fluororesin particles based on 100 parts by weight of the total amount of isocyanate group-containing 1,2-polybutadiene and an OH group-containing fluororesin composition that has the following formulation:
a copolymer [I] of
(A) a perfluoroalkylalkyl (meth)acrylate and
(B) a hydroxyl group-containing (meth)acrylate,
a polymer [II] of an acrylic acid alkyl ester,
a polymer [III] of a fluorinated olefin, and
a curing agent [IV];
wherein the weight ratio of the isocyanate group-containing 1,2-polybutadiene and the OH group-containing fluororesin composition is 50:50 to 95:5.
