High Quality Hydroxyethyl Cellulose Powder Manufacturer

Paint is a chemical mixture that can be firmly coated over the wall surface for protection or decoration. WOTAIchem hydroxyethyl cellulose is a nonionic polymer that dissolves in cold or hot water to form a colourless, transparent solution. It is a common additive in coatings with various properties:


1. Suspension and thickening.

2. Adhesion and dispersion.

3. Emulsification and film formation.

4. Water retention, colloid protection, and salt resistance.


HEC cellulose has different viscosities in waterborne paints. High, medium, and low density. Each has a certain corresponding effect.


The high thickening effect of HEC is used for mortar paint. It protects to enhance durability. Medium viscosity is more suitable for high pigment volume concentration.


HEC cellulose in water-based paint achieves several goals at the same time. Fast and efficient solubility is the best point. It effectively enhances color modifications while producing an appropriate thickening effect.


HEC additives provide different color variants to the waterborne paint for color modification.


HEC is known as a versatile paint thickener. It is a frequently used additive in paint and coating formulations due to its ability to enhance viscosity. It makes better flow and leveling properties.


HEC is also a water-binder and thickening agent for many industrial uses, such as cosmetics and personal care, building materials, adhesives, etc.

Hydroxyethyl Cellulose in Real-Stone Paint

Real stone paint is with a decorative effect similar to marble. It’s made of different colors of natural stone powder. Applicable to the exterior walls. Buildings decorated with real stone paint look pleasant and elegant with an aesthetic appearance.


Good quality hydroxyethyl cellulose powder in real stone paint prevents splash and reduces environmental pollution. HEC reinforces the top painting structure so that the color and lustre are uniform during construction. Apart from that, HEC also adds adhesion power and good compatibility and improves water resistance.


Hydroxyethyl Cellulose in Latex Paint

Latex paint is a water-based paint. Similar to acrylic paint, it is made of acrylic resin. Unlike acrylic, it is recommended to use latex paint when painting large areas.


Hydroxyethyl cellulose HEC is a thickener commonly used in latex paint formulations to increase viscosity. It improves the flow and leveling properties. HEC thickener also prevents deposition and delamination of the latex paint.


The application of HEC in the production of latex paints also increases the PH value by improving the non-ionic properties of paints. It allows latex paint to be manufactured in stable and strong variants with various formulations.

Hydroxyethyl Cellulose Related Applications

HEC in Oil Drilling

WOTAIchem Hydroxyethyl Cellulose is used to enhance viscosity in workover and completion fluids. It helps oil producers provide clear, low-solid liquids which minimize damage to the formation. The HEC material can be used as a proppant carrier in fracturing fluids.

HEC in Daily Chemical

WOTAIchem HEC is used as a thickener and stabilizer in many different types of formulations, including liquid detergents and surface cleaners. It can help to improve the viscosity and flow properties of these products, making them easier to use and improving their cleaning performance.


Why is HEC used in latex paint?

What is the difference between HPMC and HEC?


HPMC is a more cost-effective replacement for HEC in many applications. It provides better performance in some cases. However, HEC is slightly more expensive with better stability and is widely used in construction. There are significant differences between them.

1. Chemical structure: HPMC is a chemically modified form of cellulose, replacing some hydroxyl groups with hydroxypropyl and methyl groups. On the other hand, HEC is a pure form of cellulose, modified by adding ethylene oxide groups to enhance its water solubility.

2. Water retention: HPMC and HEC are excellent water-retaining agents, preventing water loss from cementitious materials, such as mortar.

3. Rheology: Rheology is the study of how materials flow. HPMC and HEC act as thickeners and increase the viscosity of water-based formulations. However, the rheological behaviour of the two cellulose ethers is different. HPMC offers better flow properties and a smoother surface finish, whereas HEC offers more shear-thinning behaviour, which means it can be easily applied using a trowel or brush.

4. Adhesion. HPMC provides better adhesion to concrete, wood, and metal substrates than HEC because it has more hydroxypropyl groups, increasing its surface activity and providing better adhesive properties.

What is the actual effect of HEC in latex paint?

Hydroxyethyl cellulose (HEC) is a water-soluble polymer that strengthens latex paint application. As a non-ionic material and thickening additive, it’s an essential component in painting projects, enhancing the usability of this versatile product. HEC is vital in producing latex paints, as different ingredients can improve various dishes during cooking.

Why does the viscosity of HEC in paint decrease every week?

It’s normal for the viscosity of HEC to decrease over time. In latex paint, HEC prevents paint from separating and maintains uniformity, even after the can is opened. This decrease in viscosity doesn’t cause layering.


HEC’s dispersibility helps evenly distribute various materials. It can ensure consistent color throughout the paint.

Is hydroxyethyl cellulose safe?

The CIR, as in Cosmetic Ingredient Review Expert Panel, has studied the safety of Hydroxyethylcellulose and determined that it is safe to use in cosmetics and personal care products.

Why does skim coat develop bubbles?

The occurrence of bubbles in skim coat can be attributed to several factors from a customer’s perspective:

– The system’s alkaline nature: Introduction of acidic substances leads to the release of carbon dioxide due to the decomposition of calcium carbonate.

– Quality of latex powder: Inferior products may result in excessive air bubble formation.

– Cellulose ether: While neutral to weak alkaline, this substance requires exposure to air to function but should not lead to bubbling.

– Bubbling on walls: If the wall is a concrete base, bubbles might form due to the need for interface agents for tile adhesion.

– Applying skim coat to tiles: Application to tiles might result in bubble formation.
