White powdery hydroxypropyl methyl cellulose in construction is a non-ionic cellulose ether, which has the following characteristics:
stability
Used as a film-forming agent, thickener, emulsifier and stabilizer in latex paints and water-soluble resin paints, to make the coating film have good wear resistance, uniformity and adhesion, and improve surface tension and PH stability , And compatibility with metallic colorants, in water-based paints, this product has excellent storage stability, maintains a uniform viscosity, makes pigments evenly dispersed, and is basically not affected by PH value.
Water retention
The main role of cellulose in putty is to retain water, adhesion, lubrication and other functions. It has high water retention, surface optical rotation performance and improved uniformity. Avoid skinning and de-powdering phenomenon, improve shrinkage resistance and crack resistance, improve anti-sag performance, and make it more comfortable and labor-saving after scraping to improve work efficiency
Thickening
In the interface agent, it is mainly used as a thickener, which can improve the tensile strength and flexural strength. Improve the surface coating, enhance adhesion, and improve the bonding strength of mortar. Good permeability, improve the uniformity of the interface. Enhance the lubricity and fluidity of the mortar, make it easier to apply and improve work efficiency.
Constructability
Tile adhesive is used as water retention agent and adhesive in the bonding of tiles, which can greatly improve the construction performance of the binder, allow a longer opening time and stronger bonding force, and prevent the tiles from losing water too fast. Shedding etc. It has improved workability, good water retention, enhanced adhesion, and high sag resistance. The efficiency of sticking bricks is improved, the efficiency of tiling is improved, and the bonding strength and shear strength are improved.
