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.

Hydroxypropyl Methyl Cellulose (HPMC) Used for ETICS/EIFS
Thermal insulation board system, generally including ETICS (EIFS) (External Thermal Insulation Composite System / Exterior Insulation Finish System),in order to save cost of heating or cooling power, a good bonding mortar needs to have: easy to mix, easy to operate, non-stick knife; Good anti-hanging effect; Good initial adhesion and other characteristics. The plaster mortar needs to have: easy to stir, easy to spread, non-stick knife, long development time, good wettability for the net cloth, not easy to cover and other characteristics. The above requirements can be achieved by adding suitable cellulose ether products like Hydroxy Propyl Methyl Cellulose(HPMC) to the mortar.

Hydroxypropyl Methyl Cellulose (HPMC) Used for Water-based Paint
Water-based paint/coating is given priority to with colophony, or oil, or emulsion, add some corresponding assistants, with organic dissolvent or water make up and become sticky liquid. Water based paint or coatings with good performance also have excellent operating performance, good covering power, strong adhesion of the film, good water retention and other characteristics; Cellulose ether is the most suitable raw material to provide these properties.

Hydroxypropyl Methyl Cellulose (HPMC) Used for Detergents
With the continuous improvement of people’s living standards, shampoo, hand sanitizer, detergents and other daily chemical products have become indispensable in life. Cellulose ether as an essential additive in daily chemical products, it can not only improve the consistency of the liquid, the formation of stable emulsion system, foam stability, but also improve the dispersion.
