    摘要： 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.

    摘要翻译： 涂布在弹性模塑模表面上的表面涂层剂，其是通过使多元醇与芳族多异氰酸酯反应得到的聚氨酯的溶剂溶液。 表面涂层剂可以涂覆在弹性模塑模具的内表面上以形成涂层，从而获得具有表面光泽度的模制品。 此外，表面涂层剂可以与硅酮和/或氟化合物结合，以提高弹性模塑模具的耐油性，防止弹性模塑模具被成型材料的油组分溶胀并提高耐久性。 当使用聚醚型多元醇作为多元醇时，可以进一步提高弹性模塑模具的耐水性。 使用聚碳酸酯多元醇作为多元醇的表面涂布剂改善了与弹性成型模具的粘合性，从而提高了耐久性。 此外，通过在底漆涂布之后或在酸处理之后，或在酸处理和底漆涂布之后涂覆表面涂层剂，表面涂层可以甚至更可靠地粘合到弹性模塑模具的表面。

    摘要： Elastomer structures having exposed controlled surface release characteristics can be made by coating at least a portion of their surface with a releasing composition comprising (a) a chlorosulphonated polymer; (b) a reinforcing filler and (c) a green tackifying agent. Optionally, these compositions can also contain a chemical curing system and one or more volatile solvent/diluent viscosity-reducing vehicle. In a specific example, the coating are applied to flexible structures used in machines for the manufacture of articles having natural tack due to their rubber or elastomer content.

    摘要： Disclosed are several methods of parting rubber from an underlying surface. Polyvinyl alcohol, methylcellulose, starch derivatives and dextran are all suitable parting agents of rubber. Polyvinyl pyrrolidone is a paticularly effective parting agent for use in the formation of balloon-type medical catheters; it is also useful as a parting agent in the formation of synthetic membranes, blood vessels and conduits. The invention includes the method of use of these parting agents as well as the products formed by the disclosed process(es). Also disclosed is a method of forming a synthetic blood vessel of a polymer material, e.g., polyurethane.
