Hydroxypropylmethylcellulose applications

Wall Putty
In water-resistant putty powder, HPMC chemicals are mainly used to improve the water retention, crack resistance, and painting performance of internal and external wall construction, so that the putty surface is sufficiently hardened and smooth, as well as the adhesion with the putty. Putty and wall are improved. It can improve the ease of putty powder. At the same time, it can improve the anti-sagging ability and enhance the fluidity, so as to improve the working efficiency. The high water retention of hydroxypropyl methyl cellulose can extend the working time of mortar. Putty powder without adding cellulose ether is very sticky and hard to scrape. So the putty powder is easy to hang or waste material.
In mortar
In cement mortar, HPMC chemicals play the roles of water retention, thickening, delaying cement hydration and improving construction performance. Its good water retention ability makes the hydration of cement more complete, which can improve the wet viscosity of mortar, increase the bonding strength of mortar, and make the mortar adhere better to the bottom surface.
In gypsum
Hydroxypropyl methyl cellulose plays an important role in water retention, lubrication and lubrication of gypsum products. Different gypsum has different effects on the performance of gypsum products, so thickening, water retention and retardation determine the quality of gypsum building materials.
External Wall Insulation System
In the external wall insulation system, the use of HPMC can improve the ease of use, water retention, open time and regular physical properties of external wall insulation mortar products. It can improve the adhesion, especially to EPS/XPS and mineral wool boards. It can improve the bonding of mortar, prevent cracking and enhance long-term durability.
Tile Adhesive
In tile adhesives, the high water retention of hydroxypropyl methylcellulose significantly improves bond strength without the need to pre-soak or wet tiles and foundations. The slurry can be applied for a long time, is fine and even, easy to apply, and has good anti-slip properties.
Sealer
Adding hpmc to the tile sealant gives the sealant good edge adhesion, low shrinkage, and high abrasion resistance. It protects the substrate from mechanical damage and avoids the negative effects of water infiltration on the whole building.
Other aspects
Chinshang HPMC powder is used as thickener, stabilizer, emulsifier, excipient, water retaining agent, film-forming agent, ETC in coatings, building materials, paint stripper, pesticides, inks, textile printing and dyeing, ceramics, papermaking, cosmetics and other products.
