The Role of Hydroxyethyl Cellulose in Stone-like Paint

Stone-like paint, also known as liquid stone, is an exterior wall coating that uses natural stone powder as its main raw material to simulate the decorative effect of granite, marble, and other natural stone. It features a natural color, strong adhesion, excellent weather resistance, stain resistance, and waterproofing, and is easy to apply, suitable for various curved surfaces and complex facade designs.

In stone-like paint systems, hydroxyethyl cellulose (HFC) acts as a key additive, primarily playing the following roles:

Preventing Splashing and Reducing Waste: Effectively reduces material rebound during spraying, improving construction efficiency and reducing waste and environmental pollution.

Enhancing System Stability: By forming a three-dimensional network structure, it prevents filler sedimentation, ensures product uniformity during storage and transportation, and improves the opening effect.

Enhancing Water Resistance and Anti-Whitening Properties: Good compatibility with emulsions promotes the formation of a dense paint film, improves the coating's water resistance, and reduces surface whitening in rainy seasons or humid environments.

Optimizing Workability and Film-Forming Effects

It imparts suitable rheological properties to the coating, making it easier to control during application, resulting in a smooth and uniform film, which facilitates even coverage of the topcoat and saves on topcoat usage.

Improving Mildew and Antimicrobial Properties

Its polymer structure possesses certain antimicrobial capabilities; when used in conjunction with bactericides, it can further enhance the mildew resistance and durability of the coating film.

In summary, hydroxyethyl cellulose in stone-like paints not only improves the product's workability and storage stability but also enhances the overall performance and decorative effect of the coating, making it a crucial component in achieving high-performance stone-like paints.
