Hydroxyethyl Cellulose (HEC) is widely used in exterior wall coatings. The following are some common applications and characteristics of hydroxyethyl cellulose in exterior wall coatings:
Viscosity adjustment: Hydroxyethyl cellulose can adjust the viscosity of the paint, making it easier to apply and spread. It can increase the viscosity of the paint, prevent the paint from running and dripping, and improve the adhesion and coverage of the paint.
Improve leveling: Hydroxyethyl cellulose can improve the leveling of paint, making the paint more smooth and even when applied. This helps reduce bubbles, spots and texture on the paint surface, providing a more aesthetically pleasing finish.
Increase crack resistance: Hydroxyethyl cellulose can increase the flexibility and crack resistance of coatings. It creates a kind of network structure in the paint, which increases the strength and durability of the coating and reduces the risk of cracking and peeling.

Hydroxyethyl Cellulose (HEC) is a natural polymer material cellulose as raw material.
Hydroxyethyl Cellulose (HEC) can be dissolved in cold water to form a transparent, viscous solution.
Application
1.Hydroxyethyl Cellulose Ether Hec is generally used as a thickener, protective agent, adhesive, stabilizer, and additive for the preparation of emulsions, jellies, ointments, lotions, eye drops, suppositories, and tablets.
2.Hydroxyethyl Cellulose Ether is used as a sizing agent in the textile industry, as an auxiliary agent for bonding, thickening, emulsifying, and stabilizing in the electronics and light industry sectors.
3.Hydroxyethyl cellulose is used as surfactant, colloidal protective agent, emulsification stabilizer for vinyl chloride, vinyl acetate and other emulsions, as well as viscosifier, dispersant and dispersion stabilizer for latex.
4.Hydroxyethyl cellulose is widely used in printing and dyeing, textile, papermaking, medicine, sanitation, food, cigarette, pesticide and fire extinguishing agent, etc.
