Paint Application Guide

High thickening effect

● HEC provides excellent coating performance for the latex coating, especially the high PVC coating. There is no flocculation when the paint is thick paste.

●HEC has a higher effect of thickening, can reduce the dosage to improve the economic effectiveness of formulation, while improving the washability of the coating.

Excellent rheological properties

● In the stationary state, the product is completely dissolved, the best coating system to maintain shape and cans thickening state.
● In the tilting state, the system will maintain moderate viscosity, make the product equipped with excellent liquidity, and will not splash.
● During the brushing and roller coating, the product is easy to spread on the base  material, which will facilitate the construction. At the same time, have a good performance on anti-splash.
● Finally, when the paint coating is completed, the system viscosity can immediately resume, and the coating will be sagging at once.

Dispersion and solubility

● HEC is dissolved after a delay in processing, in the case of dry powder added, can effectively prevent caking. Ensure that HEC powder begin to hydration after fully dispersed.
● After proper surface treatment, HEC can adjust the dissolution rate and viscosity increasing speed well.

Storage stability

● HEC has good bio-stability, provide sufficient time for the paint store. Effectively prevent and pigments and filler sedimentation.
