Hydroxypropyl methylcellulose (HPMC) is a non-ionic cellulose ether made from the natural polymer material cellulose through a series of chemical processes. It is a non-toxic and odorless white powder that forms a transparent viscous colloid when fully dissolved in water. Adding hydroxypropyl methylcellulose to building materials can significantly improve the performance of building materials and greatly improve construction efficiency and quality. and can improve the performance of some construction materials such as plastering mortars, waterproofing mortars, coatings and adhesives.
Wall Putty
In water-resistant putty powder, hydroxypropyl methylcellulose is mainly used to improve the water retention, crack resistance and coating performance of internal and external wall construction, so that the putty surface is fully hardened and flat, and the adhesion between putty and wall is improved. It can improve the construction performance of putty powder, while improving the anti-sagging ability and enhancing fluidity, thereby improving construction efficiency. The high water retention of hydroxypropyl methylcellulose can extend the construction time of mortar. Putty powder without cellulose ether has high viscosity, is not easy to scrape flat, and is prone to sagging or waste.
In mortar
In cement mortar, HPMC chemicals play the role of water retention, thickening, delaying cement hydration and improving construction performance. Its good water retention makes cement hydration more sufficient, which can improve the wet viscosity of mortar, increase the bonding strength of mortar, and make mortar better bonded to the bottom surface.
Gypsum
Hydroxypropyl methylcellulose plays an important role in the water retention, shaping, and lubrication of gypsum products. Different gypsums have different effects on the performance of gypsum products. Thickening, water retention, and slow setting determine the quality of gypsum building materials.
Exterior wall insulation system
In the exterior wall insulation system, the use of HPMC can improve the construction, water retention, open time, and general physical properties of exterior wall insulation mortar products, improve adhesion, especially the adhesion to EPS/XPS and mineral wool boards, improve the adhesion of mortar, prevent cracking, and enhance long-term durability.
Tile adhesive
In tile adhesives, the high water retention of hydroxypropyl methylcellulose can significantly improve the bonding strength without pre-soaking or wetting tiles and foundations. The slurry can be applied for a long time, is delicate and uniform, easy to apply, and has good anti-slip properties.
Sealant
Adding HPMC to tile grout can make the grout have good edge adhesion, low shrinkage, and high wear resistance, which can protect the substrate from mechanical damage and avoid water penetration from negatively affecting the entire building.
1. Non-toxic. Safe to use without any health risks.
2. HPMC can increase viscosity and has thickening and adhesion effects.
3. Stabilizer. HPMC maintains formula stability and prevents separation or precipitation.
4. HPMC improves water retention.
5. HPMC is biodegradable. It will break down over time and is an environmentally friendly material.
