Hydroxypropyl methylcellulose (HPMC) is a derivative of Methyl cellulose. HPMC is a non-ionic cellulose ether made from natural renewable polymer, such as cotton or wood pulp. It is an odourless, tasteless and non-toxic white powder, which can be dissolved in cold water to form a transparent viscous solution.
Hydroxyethyl methylcellulose HEMC provides many of the same benefits as other methylcellulose derivatives, such as the ability to efficiently thicken and provide water retention, These products are highly effective additives used to improve the quality and processing characteristics of building materials such as plasters and renders, mortars, tile adhesives, joint compounds and emulsion paints.
