Hydroxy Propyl Methyl Cellulose HPMC is a non-ionic, water soluble cellulose ether. It is widely used as thickener, protective colloid, stabilizer, suspending aids and water-retention agents in many industrial applications. It enhances water-retention, besides providing well-balanced properties including open time, slip resistance, adhesion, good impact resistance and shear strength.
1.Used as a binder in plaster, gypsum, putty powder, mortar or other building materials to improve processability and extend operating time. Prevents the slurry from drying and cracking too quickly after spraying, and the strength is enhanced after hardening.
2.Used as a tackifier for tiles, marble and plastic finishes.
1.Used as a thickener, dispersant and stabilizer in the coatings industry. Good compatibility with water or organic solvents.
