摘要： A method for improving the quality of a mastic coating system by using a latex barrier tiecoat which is composed of a water-insoluble latex polymer and a multivalent metal ion. The tiecoat is applied to a substrate and then a mastic coating is applied to the tiecoat to yield a mastic coating system having excellent resistance to blistering when the mastic coating system is exposed to long-term ponded water.

摘要： Redispersible polymer powders made by core-shell polymers having an alkali-soluble emulsion polymer shell and an aqueous-insoluble emulsion polymer core wherein the core and the shell polymers are chemically grafted by utilizing a polyfunctional compound. The core-shell polymers are produced by a two-stage sequential emulsion polymerization process in which an alkali-insoluble emulsion polymer core is polymerized in the presence of an alkali-solubilized emulsion polymer. When the core-shell polymer powders of this invention are employed as a cement modifier, improvements in the powder physical properties and cement mortar properties are realized.

摘要： The present invention relates to water-based pressure sensitive adhesives comprising at least one water-based polymer and at least one aminoplast resins such as melamine-formaldehyde resins, urea-formaldehyde resins, alkylated melamine-formaldehyde resins and combinations thereof. More particularly, the invention relates to water-based pressure sensitive adhesives comprising the reaction product of aqueous polymer dispersions and water dispersible melamine-formaldehyde resins. The pressure sensitive adhesives are characterized as having enhanced bonding characteristics including loop tack, peel strength, and shear strength making them particularly useful for the manufacture of dry-bonded laminates, tapes, labels, medical patches and devices, flexible packages, furnace ducts, exterior insulating finish system and the like.
摘要翻译：本发明涉及包含至少一种水基聚合物和至少一种氨基塑料树脂如三聚氰胺 - 甲醛树脂，脲 - 甲醛树脂，烷基化三聚氰胺 - 甲醛树脂及其组合的水基压敏粘合剂。更具体地，本发明涉及包含聚合物水分散体和水分散性三聚氰胺 - 甲醛树脂的反应产物的水基压敏粘合剂。压敏粘合剂的特征在于具有增强的粘合特性，包括环粘性，剥离强度和剪切强度，使得它们特别可用于制造干粘合层压材料，带，标签，医疗贴片和装置，柔性包装，炉管，外部绝缘整理系统等。
