  • Publication number: 20100203259
    Abstract: A method for forming a coating film able to reduce curing time, reduce the size of coating equipment and reduce the amount of CO2, without deterioration in such properties as water resistance and weather resistance. The method for forming the coating film includes the steps of (1) applying a base coating composition, (2) applying a top coating composition on the base coat layer obtained in said step (1), (3) irradiating energy line on the uncured coating film obtained in step (2), and (4) bake curing after step (3). The top coating composition includes a hydroxyl group-containing resin (A), an activation energy line-curable compound containing an unsaturated bond (B), and a polyisocyanate compound (c), with a compounding proportion of (A), (B) and (C) based on weight satisfying the ratio: ((A)+(C))/(B)=90/10 to 50/50.

  • Patent number: 7303712
    Abstract: Injection molding of a product and compressive decoration molding of a surface of the molded product are performed using individual cavity molds. A decorative film can be molded efficiently with a thermosetting coating material under suitable temperature control regardless of the shape of the molded product. An injection cavity mold and a decoration cavity mold are employed. The injection cavity mold is set at a hardening temperature of a thermoplastic resin. The decoration cavity mold is set at a thermosetting temperature of a coating material. A molded product is injection-molded in the cavity mold for injection molding and released from the mold. A decorative coating material composed of a liquid thermosetting composition is mounted at least on a part of the top of the injection-molded product. The molded product is located within the cavity mold for decoration molding.

An injection cavity mold and a decoration cavity mold are employed. The injection cavity mold is set at a hardening temperature of a thermoplastic resin. The decoration cavity mold is set at a thermosetting temperature of a coating material. A molded product is formed by injection molding in the injection cavity mold. The injection molded product is located within the decoration cavity mold to create a space as a cavity for decoration molding between an inner surface of the decoration cavity mold and a surface of the injection molded product.
