HPMC For Interior Wall Putty

Wall putty, also known as degreasing paint. This is a material used for preparing and smoothing walls before painting. Hydroxypropyl methylcellulose is a commonly used raw material in interior wall putty powder. It can greatly improve the smoothness and anti-sagging properties of construction, improve wettability, improve the anti-slip properties of putty, improve the leveling effect of putty, and improve construction efficiency.

Product Details

Hydroxypropyl methylcellulose (HPMC) is a non-ionic cellulose ether made from natural macromolecular material cellulose through a series of chemical processes. Hydroxypropyl methylcellulose (HPMC) is an odorless, tasteless, non-toxic white powder that can be dissolved in cold water to form a transparent viscous solution. It has the functions of thickening, bonding, dispersing, emulsifying, film-forming, suspending, adsorbing, gelling, surface activity, water retention, and protective colloids.

Instant-soluble HPMC in elastic interior wall water-resistant putty paste has the characteristics of easier scraping, easy scraping, no need for grinding, easy polishing, light collection, and calendering. The coating is white and delicate, and the hand feel is smooth, similar to Chinese porcelain. HPMC has good lubrication properties and can significantly improve the construction performance of putty powder, making the construction process smoother. It can also reduce dust generation during construction and improve construction efficiency. ‌

By improving the water retention and thickening properties of putty powder, HPMC can help the putty surface to fully harden and smoothen, thereby improving the quality and durability of the putty surface and making the putty layer more solid and beautiful‌.‌

FAQ

What is the main use of 1-Hydroxypropyl methylcellulose (HPMC)?

HPMC is widely used in industries such as construction materials, coatings, synthetic resins, ceramics, pharmaceuticals, food, textiles, agriculture, cosmetics, and tobacco. HPMC can be classified into architectural grade, food grade, and pharmaceutical grade based on its application. Currently, most domestically produced HPMC falls under the architectural grade category. In the architectural grade, a large amount of HPMC is used in putty powder, accounting for approximately 90% of its usage, while the rest is used in cement mortar and adhesives.
