Process for producing urethane moulding

A process for producing a urethane die. A heat-resistant epoxy adhesive is applied to the inner surface of a recess provided in the body of a die. A urethane primer is applied to the adhesive while the adhesive is still in a semi-hardened state. A punch is inserted into the recess to form a space between the recess and the punch and a urethane resin is injected into the space to form a resin layer on the recess having a shape corresponding to the outer surface of the punch. A reinforcing fibrous material may be incorporated into the resin layer by applying a urethane resin having a lubricant incorporated therein to the surface of the punch and adhering a fibrous material impregnated with the urethane resin to the coated surface of the punch prior to inserting the punch into the recess.

POLYURETHANE MOLDING PROCESS WITH SILOXANE INTERNAL RELEASE AGENT

P-585 TITLE Polyurethane molding process with siloxane internal release agent. An improved polyurethane RIM process using a polycarboxy-functional alkyl siloxane as an internal release agent characterized by: (1) Tool break-in or preconditioning with siloxane treatment of the surfaces; (2) Supplying the siloxane to the mix head as a third stream when necessary to prevent undesired side reactions; (3) using a minimal amount of siloxane that is inadequate for mold release in the absence of the tool preconditioning; (4) Adjustment of catalyst package to counter the inhibiting effects of the siloxane. The use of a bare minimal amount of siloxane prevents excess siloxane from appearing in the surface of the article and causing subsequent paint wet-out and like difficulties. The third stream isolating of the siloxane prevents its carboxy-functional groups from reacting with the prepolymer or with other ingredients that may be P-585 carried in the polyol blend.

Surface coating agent surface coating method for elastic molding die

Abstract of the Disclosure A surface coating agent to be coated on the surface of an elastic molding die, which is a solvent solution of a polyurethane obtained by reacting a polyol with an aromatic polyisocyanate. The surface coating agent can be coated on the inside surface of the elastic molding die to form a coating layer, thereby obtaining a molding with surface gloss. Further, the surface coating agent can be incorporated with silicone and/or a fluorine compound to improve oil resistance of the elastic molding die, preventing the elastic molding die from being swollen by oil components of a molding material and improving durability. When a polyether type polyol is used as the polyol, water resistance of the elastic molding die can be even further improved. The surface coating agent using polycarbonatepolyol as the polyol has improved adhesion to the elastic molding die, thereby improving the durability. Further, the surface coating layer can be even more securely bonded to the surface of the elastic molding die by coating the surface coating agent after primer coating, or after acid treatment, or after acid treatment and primer coating.
