摘要： This invention relates to an organic foundry binder containing an alkyl resorcinol, or preferably a readily available mixture of alkyl resorcinols, and derivatives thereof. Preferably, the organic foundry binder is a furan binder. Foundry mixes are prepared by mixing the binder with a foundry aggregate. Foundry shapes (molds and cores) are prepared by shaping the mix and allowing it to cure to form a workable foundry shape. The invention also relates to the preparation of metal castings using the foundry shapes and the metal castings prepared with the foundry shapes.

摘要： The present invention is based on the unexpected discovery that the low profile additives (LPA) disclosed in U.S. Pat. No. 5,116,917 provide effective shrinkage control when used with various blends of vinyl ester and polyester resin systems. This LPA is unique in that its low profile efficiency is not affected by the different reactivities displayed by blends of vinyl ester resin and polyester resin at different blend ratios. This LPA is equally effective in formulations of all vinyl ester resin, all polyester resin, or any combination of such two resins. The present invention, then, is directed to a thermosettable resinous composition of between about 0 and 95 wt-% of a thermosettable vinyl ester resin; between about 5 and 100 wt-% of a thermosettable polyester resin; and between about 5 and 40 wt-% of a low profile additive comprising a non-gelling, saturated polyester formed from dibasic acid and an EO/PO block copolymer having an EO/PO molar ratio ranging from about 0.1 to 0.9, said polyester having an acid value of greater than about 10. The EO/PO polyether polyol can be built on a combination of diol, triol or other compound with active hydrogen groups, so long as the LPA product does not gel.
摘要翻译：本发明基于意想不到的发现，即在美国专利No. 当与乙烯基酯和聚酯树脂体系的各种共混物一起使用时，提供了有效的收缩率控制。该LPA是独特的，因为其低轮廓效率不受不同共混比下乙烯基酯树脂和聚酯树脂的共混物显示的不同反应性的影响。该LPA在所有乙烯基酯树脂，所有聚酯树脂或这两种树脂的任何组合的配方中同样有效。然后，本发明涉及可热固的乙烯基酯树脂的约0至95重量％的热固性树脂组合物; 约5-100重量％的热固性聚酯树脂; 和约5至40重量％的低分子添加剂，其包含由二元酸形成的非胶凝的饱和聚酯和EO / PO摩尔比为约0.1至0.9的EO / PO嵌段共聚物，所述聚酯具有大于约10的酸值。只要LPA产物不凝胶，可以将EO / PO聚醚多元醇构建在二醇，三醇或其它化合物与活性氢基团的组合上。
