Water-Based Sand-Coated Multicolor Coatings Solution

In recent years, multicolor stone-effect coatings have maintained rapid growth as the hottest exterior wall decorative coatings, with market share increasing annually. Beyond the efforts of coating manufacturers, the thriving development of these coatings relies equally on high-performance architectural emulsions. We consistently strive to provide customers with energy-efficient and environmentally friendly products, safeguarding the decorative appeal and longevity of building exteriors.

Water-in-Water Multicolor Coatings
Advantages: Excellent stone-like effect, highly realistic, indistinguishable from genuine stone.
Disadvantages: Smooth surface lacks texture.

Natural Stone Paint
Advantages: Textured finish, high cost-effectiveness
Disadvantages: Inferior stone imitation effect; natural marble-like patterns cannot be replicated due to reliance on natural colored sand as raw material.

Water-in-Sand paint combines the strengths of both, offering the textured feel of natural stone paint alongside the stone-like effect of water-in-sand coatings.

We analyzed various factors causing instability in the continuous phase viscosity of protective gel liquids and proposed countermeasures. We specifically developed protective emulsion stabilizer ST-3 to ensure long-term anti-gelation and viscosity stability (the foundation for multicolor coating stability). ST-3 also incorporates components that perform hydrophobic surface modification on the protective emulsion, similar to the organic modification of bentonite. This modification plays a crucial role in stabilizing color particles (preventing fusion and color bleeding). Base Coat Stabilizer ST-2 specifically shields base coats (including color coats) from factors that cause thickening after protective emulsion gelation. It also significantly enhances color particle stability against high-speed shear. At 1300 rpm, particles only shear into smaller fragments without causing overall coating failure.
