Abstract
The disclosure discloses a method for forming a rubber layer on a surface of a resin material. In the method, painting is first performed on the surface of the resin material to form a painting layer, using a paint to which a pigment has been added; then, rubber coating is performed to form a rubber layer on the painting layer. The method of the disclosure may be used in surface treatment of a fastener product. The disclosure further discloses a slide fastener, a buckle and a snap button using the method of the disclosure. The method of the disclosure may solve a conventional problem that a rubber coating is likely to fall off a resin surface, and the rubber on the surface of the resultant fastener product is less likely to fall off.
