HEC: "Smart Regulator" for Water-Based Coatings

As a green additive certified by ISO 9001, hydroxyethyl cellulose (HEC) has been successfully applied to the formulation systems of global TOP10 coating companies such as Nippon Paint and Dulux. Its key technical value in water-based coatings is reflected in three dimensions:

I. Precise rheological control

• Smart thickening: Build a three-dimensional network through molecular chains (viscosity range 500-10,000cps) to achieve a perfect balance between construction shear thinning (construction viscosity reduced by 40%) and high static stability

• Anti-sagging technology: The vertical surface construction thickness is increased by 50%, and the ASTM D4400 test in the United States shows that the sagging index is reduced by 60%

• Anti-splash optimization: The amount of roller coating splash is reduced by 35% (measured data comes from PPG laboratory)

II. Full system stabilization solution

Pigment suspension: The steric hindrance effect makes the sedimentation rate of pigments such as titanium dioxide less than 5% (GB/T 9268 requires less than 10%)

Freeze-thaw stability: Passed ASTM D2243 standard test, viscosity retention rate after 5 cycles> 90%

PH adaptability: maintain stable performance within the range of 2-12, suitable for epoxy/acrylic and other systems

III. Sustainable construction guarantee

• Extended open time: single roller coating area increased by 30%, and actual construction efficiency increased by 25%

• Film formation optimization: water slow release technology increases emulsion coagulation by 18%, and low-temperature film formation integrity reaches Class A

• Environmental certification: passed REACH, FDA 21CFR175.300 and other international standards, VOC content <5g/L

Global building materials laboratory tests show that the storage stability of latex paint with 0.5% HEC added is extended from 3 months to 18 months, and the number of scrub resistance is increased to 6,000 times (exceeding the national standard of superior products by 2 times). The latest research by Dow Chemical confirms that HEC-modified water-based wood paint has a 20% shorter drying time and an increase in leveling by 15 gloss units.
