Application

In construction, HPMC is mainly used for mechanized constructions like building the wall, adorning with parget and caulking etc. In decorative constructions, it was used for sticking ceramic tiles, marbles and plastic accessories. It has very high bonding strength and can reduce the dosage of cement.

In water-based paints, the product is of good shelf stability to keep homogeneous viscosity and dispersion of pigments. The product shows different levels of enzyme resistance with different viscosities. Product with higher viscosity is of better enzyme resistance. Film thickened by the product is of rapid coating performance, high adhesiveness, and resistance to scrapping, raining and freezing, as well as excellent homogeneity. Further more, due to its water retention, coating performance and good leveling property, it is helpful to improve the applications of paints and homogeneity of films.

As a kind of binder for the molded refinery ceramic products, the relatively-high concentration solution of the product can be adsorbed on the surface of the ceramic grains, which can minimize the friction between the ceramic grains and improve the lubricity. Thus the molded ceramic products can obtain the desired surface smoothness and dimension stability. Additionally, the low ash content of this cellulose ether product contributes to the excellent electric properties of the sintered ceramic product.
