Hydroxypropyl Methyl Cellulose (HPMC)

Hydroxypropyl methyl cellulose is a kind of nonionic cellulose ether which is made from natural polymer material through a series of chemical processing. It contains almost all properties of methyl cellulose. It has been widely used in construction building materials with high water retention, good dispersion, good adhesion, easy dissolution and so on. It is always used for dry mixed mortar, wall putty powder, tile adhesives, joint fillers, Water soluble paints, coatings, self-leveling and gypsum materials. 

羟丙基甲基纤维素是以天然高分子材料为原料，经过一系列化学加工而成的非离子型纤维素醚。它几乎包含了甲基纤维素的所有性质。它具有保水性高、分散性好、附着力好、易溶解等特点，已广泛应用于建筑建材中。常用于干混砂浆、墙面腻子粉、瓷砖粘合剂、接缝填充剂、水溶性涂料、涂料、自流平、石膏材料等。
