Hydroxypropyl methylcellulose (HPMC) is a non-ionic cellulose ether obtained by a series of chemical processing using natural polymer materials (purified cotton) as a raw material.
HPMC is an odorless, non-toxic, odorless white powder that dissolves in cold water to form a clear, viscous solution, with good water retention, thickening, emulsification, film formation, suspension, adsorption, gelation, surface activity and protective colloids.
The products are widely used in waterborne coatings, interior and exterior wall putty powder, thermal insulation mortar series and other product systems.
The redispersible polymer powder is a powder binder prepared by spray drying a special emulsion(polymer).
The powder can be quickly dispersed into an emulsion after contact with water, and has the same properties as the initial emulsion, that is, a film can be formed after evaporation of water, the film has high flexibility, high weather resistance and various kinds of High adhesion of the substrate.
