Abstract
A coating agent aqueous dispersion comprising, as solid matters, 20 to 80 wt. %, preferably 29 to 70 wt. %, of PTFE, 10 to 50 wt. %, preferably 14 to 36 wt. %, of acrylic resin, and 10 to 50 wt. %, preferably 20 to 45 wt. %, of ethylene-vinyl acetate copolymer resin. When the coating agent aqueous dispersion of the present invention is used as a surface-treating agent for rubber-made sealing materials, etc., a reduction in stickiness to the sealing mate material and the prevention of blooming on the surface of the rubber material are obtained. Combined with the flexibility, the adhesion balance between the rubber material and the coating agent is excellent.
