    • Method of forming or shaping a resin-bound mass (e.g., core-making or mold-making pattern or core box, particle board, etc.) in or from shaping means having shaping surfaces and releasing the shaped resin-bond mass from the shaping surfaces, which comprises coating the shaping surfaces of the shaping means with an improved, substantially stable, alcoholic dispersion or solution of a release coating suitable for repeated use, heating the coated shaping surfaces of the shaping means for sufficient time to convert the coating thereon to a stable, cured, abrasive-resistant release coating, placing a curable resin-bound mass of solids to be shaped against the release-coated shaping surfaces, curing the resin-bound mass, and separating the cured resin-bound mass from contact with the release coated shaping surfaces. The coating composition comprises a substantially stable alcoholic dispersion or solution of a substantially pure silanol of the formula RSi(OH).sub.3 or partial condensate of one or more silanols of the formula RSi(OH).sub.3, wherein R is selected from the group consisting of alkyl radicals of 1 to 3 inclusive carbon atoms, the vinyl radical, the 3,3,3-trifluoropropyl radical, the gamma-glycidoxypropyl radical and the gamma-methacryloxypropyl radical.
    • 在具有成型表面的成形装置中或从具有成形表面的成形装置中形成或成型树脂结合物质(例如,芯制造或模制制品图案或芯盒,刨花板等)的方法,并将成形树脂粘合块从成形 表面,其包括用适于重复使用的脱模涂层的改进的基本上稳定的醇分散体或溶液涂覆成型装置的成形表面,加热成形装置的涂覆成形表面足够的时间以将涂层转化为 稳定的,固化的,耐磨损的剥离涂层,将可固化树脂结合的固体物质放置成抵抗剥离涂覆的成形表面,固化树脂结合物质,以及将固化的树脂结合物质与 释放涂层成型表面。 涂料组合物包含基本上稳定的醇分散体或基本上纯的式RSi(OH)3的硅烷醇或一种或多种式RSi(OH)3的硅烷醇的部分缩合物的溶液,其中R选自 1〜3个碳原子的烷基,乙烯基,3,3,3-三氟丙基,γ-环氧丙氧基丙基和γ-甲基丙烯酰氧基丙基。

    • The invention relates to sheet molding compounds having improved viscosity control comprising polyester-polyurethane hybrid resins formed by the reaction of an A side composition and a B side composition. The A side composition comprises a polyfunctional isocyanate compound and a free radical polymerization catalyst. The B side composition comprises a mixture of (i) an ethylenically unsaturated monomer solution having no active hydrogen groups which has dissolved therein about 40-90 weight percent of a substantially water-free, unsaturated polyester polyol having at least one dicarboxylic alkene moiety and having an acid number less than five; and (ii) a methacrylate ester of a C.sub.2 -C.sub.10 alkylene diol.
