LANDU HEC for Emulsion Paint

Professional Cellulose Ether Solutions for Modern Coating Formulations

Technology Insight

What Is Emulsion Paint?

Emulsion paint is a water‑borne coating in which binders, pigments, and functional additives are stably dispersed in water using surfactants.

Because of its eco‑friendly formulation and ease of use, it's now the preferred choice for decorative and protective coatings.

Key Advantages:

✓

Low odor and environmentally friendly

✓

Smooth application and fast drying

✓

Excellent adhesion and durability

✓

Consistent finish quality with easy cleanup

To achieve these advantages, modern paints rely on advanced rheology modifiers — and HEC is the leading solution for balancing viscosity and workability.

Core Technology

Why HEC Is Essential in Emulsion Paint

HEC (Hydroxyethyl Cellulose) is a nonionic, water‑soluble polymer that acts as a powerful thickener, stabilizer, and film enhancer. Its unique rheological behavior ensures paint performs precisely as expected — from mixing tank to application.

HEC Provides:

✓

High thickening efficiency and consistent viscosity

✓

Smooth brush and roller feel

✓

Improved color acceptance and stain uniformity

✓

Longer open time and stronger water retention

✓

Anti‑sag and anti‑splatter properties

✓

Excellent storage stability and freeze‑thaw resistance

High‑quality HEC ensures paint layers spread uniformly, adhere firmly, resist cracking, and maintain a clean, attractive finish throughout their life cycle.

Usage Guide

How to Use HEC in Emulsion Paint

LANDU HEC can be incorporated using different processing methods depending on equipment and formulation design.

Addition During Pigment Grinding

The most common and straightforward method.

Steps:

Add clean water to the mixing tank.

Begin slow stirring.

Gradually add HEC powder.

Add surfactants, dispersants, and preservatives.

Continue mixing until fully hydrated and uniform.

Mother Solution Preparation

HEC is pre‑hydrated into a concentrated solution before being added to the paint batch.

Advantages:

●

Precise viscosity control

●

Easy adjustment during production

●

Reduces dusting and improves consistency

Slurry Technique

HEC is first dispersed in a compatible solvent to form a slurry and then hydrated.

Features:

✓

Faster dispersion and hydration (5–30 min)

✓

Ideal for automated dispensing lines

✓

Simplifies scaling in industrial production

Application Performance

Brush

Brush Application

HEC enhances the painter's experience with a smooth, even flow.

Performance Highlights:

✓

Uniform film formation

✓

Reduced drips and splattering

✓

Consistent color and thickness

(For spray use, dilute 15–20 % with water and filter before application.)

Roller

Roller Application

Balanced viscosity and water retention enable perfect roller behavior.

Benefits:

✓

Even coverage with fewer roller marks

✓

Efficient paint pickup and release

✓

Smooth, clean finish on walls and ceilings
