    摘要： A coating for preparing a floor underlayment to receive an adhesive, where the coating includes a water-soluble, latex polymer, a defoamer and a dual-function surface enhancing agent. The surface enhancing agent includes a set accelerator that also functions to cross link the adhesive, hardening the surface of the underlayment using at least two mechanisms. One embodiment of the invention is a dry mixture that forms a coating when added to water. The dry mixture includes from about 10% to about 50% of the redispersible polymer on a dry weight basis, from about 50% to about 90% of the surface enhancing agent and from about 0.15% to about 0.25% of the defoamer on a dry weight basis. Other embodiments describe a liquid coating formed by adding from about 1 to about 8 parts water to 1 part of the dry mixture on a volume basis.

    摘要： A gypsum slurry includes calcium sulfate hemihydrate, water and calcium sulfate dihydrate is coated with a hydrophilic, dispersible coating. The coating is less soluble than the calcium sulfate hemihydrate to delay exposure of the landplaster to the remainder of the slurry, preventing premature crystallization and the early stiffening that accompanies it.Another embodiment is a gypsum slurry that includes calcium sulfate hemihydrate, a polycarboxylate dispersant, water and coated calcium sulfate dihydrate. In this case, the hydrophilic, dispersible coating is selected to serve as a modifier to enhance the ability of the dispersant to fluidize the gypsum slurry.

    摘要翻译： 石膏浆料包括半水合硫酸钙，水和硫酸钙二水合物涂覆有亲水的，可分散的涂层。 涂层的溶解度比硫酸钙半水合物少，以延缓露地坪暴露于泥浆的剩余部分，防止过早结晶和伴随其的早期硬化。 另一个实施方案是包括硫酸钙半水合物，多羧酸盐分散剂，水和包被的硫酸钙二水合物的石膏浆料。 在这种情况下，选择亲水性可分散涂层作为改性剂以增强分散剂使石膏浆液流化的能力。
