Document Type and Number:
WIPO Patent Application WO/2016/047641
Kind Code:
A1
Abstract:
 A surface treatment agent for vulcanized rubber, comprising an organic solvent solution containing fluororesin particles in a ratio of 10-160 parts by weight with respect to 100 parts by weight in terms of solid content of a 1,2-polybutadiene containing an isocyanate group, the organic solvent solution using as a dispersing agent 2.5-20 parts by weight of a fluorine-containing surfactant based on an oligomer containing a perfluoroalkyl group.
