Hydroxyethyl Cellulose (HEC) in Water-Based Paints

*Chemion AG's Complete Range of Biostable, High-Performance Rheology Modifiers*

Why HEC for Paint?

Hydroxyethyl Cellulose (HEC) is a water-soluble, non-ionic cellulose derivative widely used as a thickener, stabilizer, and rheology modifier in water-based coatings. In modern architectural and industrial paints, HEC plays a crucial role in:
- Controlling viscosity and flow behavior
- Suspending pigments and fillers
- Reducing spatter during application
- Improving leveling and finish
- Ensuring storage stability

Chemion AG’s HEC portfolio is specifically engineered to meet the needs of paint manufacturers seeking consistency, compatibility, and cost-efficiency.

Chemion HEB Series – Trusted Biostable Grades

Innovation Spotlight: HE430P & HE450P

CHEMION HE430P – Surface-Modified for Flow and Finish

An advanced HEC modified to improve compatibility, solubility, and workability in latex paints.
Key Benefits:
- Surface-treated for delayed solubility
- Enhanced biostability for long shelf life
- Improves application feel and brushability
- Controls sag while maintaining smooth finish
- Viscosity: 200–500 mPa.s at 1%
Ideal for mid-sheen and satin paints where flow and stability are essential.

CHEMION HE450P – Hydrophobically Modified for Anti-Spatter

This HMHEC (hydrophobically modified HEC) grade is designed to solve spatter and splashing issues during roller/brush application.
Advantages:
- Anti-spatter performance for cleaner application
- Enhanced rheological balance – no compromise on leveling
- Compatible with all binder systems (acrylic, styrene-acrylic, vinyl)
- Surface-treated, easy dispersion
- Viscosity: 200–500 mPa.s at 1%
A must-have for premium interior emulsions or DIY paints where user experience matters.
