Hydroxypropyl Methyl Cellulose (HPMC) Used for Putty

Architectural painting involves three levels: wall, putty layer and coating layer. Putty, as a thin layer of plastering material, plays the role of connecting the preceding and the following. A function is good be tired of be tired of child to assume the task that resisting base level craze, coating layer rises skin not only, make metope achieves smooth and seamless result thereby, still can make all sorts of modelling achieves adornment sex and functional sex action. Cellulose ether provides enough operation time for putty, and protect the putty on the base of wettability, recoating performance and smooth scraping, but also make putty has excellent bonding performance, flexibility, grinding, etc.

Hydroxy Propyl Methyl Cellulose (HPMC) can add water in the process of stirring, significantly reduce the friction in the dry powder, make mixing easier, save the mixing time, give putty feel light, and smooth scraping performance; Excellent water retention can significantly reduce the moisture absorbed by the wall, on the one hand, it can ensure that the gel material has sufficient hydration time, and ultimately improve the bond strength, on the other hand, it can ensure that workers on the wall of the putty for many times scratching; Modified cellulose ether, in high temperature environment, can still maintain good water retention, suitable for summer or hot area construction; It can also significantly improve the water demand of putty material, on the one hand, improve the operation time of putty after the wall, on the other hand, can increase the coating area of putty, so that the formula is more economical.
