Uses of Hydroxy Propyl Methyl Cellulose (HPMC)
HPMC is mainly used as a dispersant for suspension polymerization in industry. Due to its excellent dispersing and glue retention capabilities, products with regular particle size, concentrated particle size distribution, appropriate specific gravity and excellent processing performance can be obtained; in construction, it is used for masonry In the mechanized construction of walls, plaster decoration, caulking, etc., it is suitable for centralized dry-mixing and pre-mixed mortar, which has thickening, water-retaining and cohesive properties, and improves slurry pumpability; in decorative construction, it is used for pasting tiles, Marble, etc., has high bonding strength and can also reduce the amount of cement; used for plastering plaster, water-resistant putty, bonding plaster, caulking plaster, can significantly improve its water retention, bonding strength, etc., and has good workability and does not crack, etc. Features: Used as a thickener in the coating industry, can make the coating bright and fine, without powder removal, improve its leveling, etc.; used as a suspending agent and binder in ceramic glazes to make the pigments evenly dispersed in the glaze , Its gel properties can make the glaze thick coating and so on. In other areas such as petrochemical, construction, printing and dyeing, tobacco, daily chemical, paper, leather, agriculture and forestry and other industries and sectors, it is widely used as thickener, binder, water retaining agent, film forming agent, stabilizer, emulsifier , Excipients, etc.
