HPMC has the characteristics of - Thickening ability, salt tolerance and low ash powder, pH stability
- Water retention, dimensional stability, excellent film forming
- Extensive enzyme resistance, dispersion and adhesion.
|
- Hpmc cement mortar: improve the dispersion of cement-sand, which greatly improve the plasticity and water retention of mortar, prevent cracks, can enhance the strength of cement.
- Hpmc coating of asbestos and other refractory materials:as suspension safety agent, flowability improving agent, and improving the adhesive force to the base.
- Hpmc gypsum concrete paste: improve water retention and workability, improve adhesion to substrate.
- Hpmc tile cement: improve the plasticity of pressed tile mortar, keep water, improve the adhesive force of ceramic tile, prevent powdering.
- Hpmc joint cement: added to joint cement for gypsum board to improve liquidity and water retention
