Application Guide for the coatings industry：
High thickening effect
● Headcel Hydroxyethyl Cellulose as latex paints, especially high-PVA coating, providing excellent coating properties. Paint a thick paste, it will not produce flocculation.
● Headcel Hydroxyethyl Cellulose has a higher thickening effect. can reduce the amount of formula to improve the economy, while improving the performance of paint abrasion.
Excellent rheological properties
● Headcel Hydroxyethyl Cellulose aqueous solution of non-newtonian system, the performance of their solution have called thixotropy.
● In the stationary state, the product is completely dissolved, the best coating system to maintain shape and cans thickening state.
● In the dump state, the system to maintain moderate viscosity, making the product has excellent liquidity, and does not splash.
● Brushing and roller coating, the product is easy to spread in the substrate. Facilitate the construction. At the same time, have a good anti-splash.
● Finally, when the paint coating is completed, the viscosity immediately resume, paint immediate sag resistance.
Dispersion and solubility
● Headcel Hydroxyethyl Cellulose are dissolved after a delay in processing, in the case of dry powder added, can effectively prevent caking. Ensure that HEC powder fully dispersed, began to hydration.
● After proper surface treatment of Headcel Hydroxyethyl Cellulose, a good adjustment of the dissolution rate and viscosity of the product increased speed.
Storage stability
● Headcel Hydroxyethyl Cellulose has good mildew performance, provide sufficient time for the paint store. Effective prevention and treatment of pigments and filler sedimentation. |
