Hydroxyethyl cellulose (HEC)in aqueous liquid coating products

Water-based liquid coatings are coatings that use water as a solvent or as a dispersion medium. A waterborne coating with good performance also has to have excellent handling properties, good hiding power, good film adhesion and good water retention properties. Cellulose ethers are the most suitable raw material to provide these properties.
The effects are fourfold: protection, decoration, masking of defects and other special effects that enhance the value of the product.
Hydroxyethyl cellulose (HEC) is used in aqueous emulsion coatings, architectural coatings, emulsion paints, etc.
Recommended hydroxyethyl cellulose HEC: 30,000, 60,000 viscosity.
Cellulose ethers with the appropriate surface treatment are effective in preventing lumping during dissolution, are well dispersed. Sufficient dissolution time and viscosity rise rate simplify the production process. The modified cellulose ethers also have good anti-mould properties. Providing sufficient storage time for coatings and effectively prevent pigments and fillers from settling.

Interior emulsion paints.

HEC in aqueous liquid coating
Interior emulsion paint is a viscous liquid based on emulsions. With pigments and fillers added according to demand, with corresponding additives and prepared with water for the painting and decoration of interior walls. With the upgrading of the living environment, the requirements for interior wall products are very high. And the odourless series of polymer emulsions meet the demanding requirements for safe furniture.

Exterior emulsion paints.

HEC in aqueous liquid coating

Exterior emulsion paint is a viscous liquid based on emulsions, with pigments and fillers, added with corresponding additives. And prepared with water for the painting and decoration of exterior walls. Polymer emulsions can easily meet the harsh requirements of the outdoor climate. Such as ultraviolet light, large temperature differences between day and night, high temperature exposure, high humidity, etc.

Elastomeric coatings.

HEC in aqueous liquid coating

Elastic paint is a functional paint with polymer emulsion as the base material, formulated with pigments, fillers and additives. Application requires a certain thickness and has the ability to resist small cracks due to the expansion and contraction of the substrate with elasticity. Elastic paint is rich in expression, three-dimensional, high flexibility, plasticity, strong adhesion, scrub resistance, acid and alkali resistance, no fading, no peeling, not easy to crack. Mainly suitable for residential, school, hospital, hotel…

Colourful paint.

Multi-colour paint is mainly applied to imitate stone paint, also known as liquid stone, also called imitation granite external wall paint. It is composed of incompatible two-phase components, where one phase of the dispersion medium is the continuous phase and the other phase is the dispersion phase. When painting, a luxurious, beautiful and colourful pattern can be obtained by one-time spraying. After coating, a variety of colour patterns, strong three-dimensionality and excellent gloss can be obtained due to unevenness and dispersion.

Roof waterproofing coatings.

Roof waterproofing coating is a waterproof coating applied to the roof base, after curing to form a layer of a certain thickness and flexibility of the overall coating film, so as to achieve the waterproof effect. The roof waterproofing coating bonding strength is high, not easy to drum, good flexibility is UV, high temperature, acid and alkali corrosion resistance. And it can effectively inhibit algae production.

Sealer primers.

Sealer primer is usually an interface agent based on acrylic polymer emulsion or styrene acrylic polymer emulsion, which plays the role of reinforcing the base, sealing dust, reducing water absorption of the base and can improve the bonding performance with the base.


HEC in aqueous liquid coating

Overcoats are usually pure acrylic polymer emulsions or silicone polymer emulsions that cover the outermost layer of the overcoat emulsion. The overcoats are water resistant, UV resistant, stain resistant and somewhat self-cleaning.
