Hydroxypropyl methylcellulose (HPMC) is a non-ionic cellulose ether made from cellulose, a natural polymer material, through a series of chemical processing. It is a non-toxic, odorless white powder that will form a transparent, viscous colloid when fully dissolved in water. Adding hydroxypropyl methylcellulose to construction materials can significantly improve the performance of construction materials, greatly improve construction efficiency and quality. And it can improve the performance of some construction materials such as plastering mortar, waterproof mortar, coatings, and adhesives. Kingsun hydroxypropyl methylcellulose hpmc has the characteristics of high water retention, good dispersibility, fineness, good workability, and easy dissolution. Its viscosity and gel time can be customized according to customer needs. Besides, as a hpmc manufacturer in China, the hydroxypropyl methylcellulose price in Kingsun is very reasonable. Welcome to consult.
Application of Hydroxypropyl Methylcellulose
The Wall Putty
In water-resistant putty powders, hpmc chemical is mainly used to improve the water-retaining performance, crack resistance, and coating properties of internal and external wall construction, so that the surface of the putty is fully hardened and smooth, and the adhesion between putty and the wall is improved. It can improve the workability of putty powder. At the same time, it can improve the anti-sagging ability, enhance fluidity, thereby improving work efficiency. The high water retention of hydroxypropyl methylcellulose can extend the working time of the mortar. The putty powder without added cellulose ether has great stickiness and is difficult to scrape. So the putty powder is prone to sag or waste material.
In Mortar
In cement mortar, hpmc chemical plays a role in water retention, thickening, delaying cement hydration, and improving construction performance. Its good water-holding capacity makes the cement hydration more complete, which can improve the wet viscosity of the mortar, increase the bonding strength of the mortar, and make the mortar and the bottom surface better adhere.
In Plaster Gypsum
Hydroxypropyl methylcellulose plays an important role in water retention, regarding, and lubrication of gypsum products. Different gypsum has different effects on the properties of gypsum products, so thickening, water retention and retarding determine the quality of gypsum building materials.
External Wall Insulation System
In the external wall insulation system, the use of hpmc can improve the workability, water retention, open time, and conventional physical properties of external wall insulation mortar products. It can improve the adhesion, especially the adhesion to EPS / XPS and mineral wool board. It can improve the cohesion of the mortar, prevent cracking, and enhance long-term durability.
Tile Adhensive
In tile adhesives, the high water retention of hydroxypropyl methylcellulose can significantly improve bond strength without the need to pre-soak or wet the tiles and foundation. The slurry can be applied for a long time, it is fine and uniform, easy to apply, and has good slip resistance.
Sealant
Adding hpmc to the tile sealant can make the sealant have good edge adhesion, low shrinkage, and high wear resistance. It can protect the base material from mechanical damage and avoid the negative impact of water penetration on the entire building.
Other Aspects
Kingsun hpmc powder used as thickener, stabilizer, emulsifier, excipient, water-retaining agent in coatings, building materials, paint removers, agricultural chemicals, inks, textile printing and dyeing, ceramics, papermaking, cosmetics, and other products, Film-forming agent, etc.
