New Trends in Exterior Wall Decoration: Creating Colors Beyond Nature with Keytec's Water-based Colorants for Multi-color Paints

As the exterior wall coatings market continues to evolve, there has been a growing demand for the renovation of old buildings and the re-coating of exterior surfaces. Multi-color faux stone paint has emerged as a preferred choice for exterior wall decoration due to its vibrant colors, safety, durability, and ease of application.

These paints come in various types, including water-in-water, water-in-sand, granite effect, marble effect, and textured stone paints, each designed to replicate the appearance and texture of natural stone for decorative and architectural applications. Among these, we will focus on the water-in-sand coatings to provide a detailed comparison with traditional real stone paint.

Comparison: Water-in-Sand Coatings vs. Traditional Real Stone Paint

Realism

- Real Stone Paint: The color palette of real stone paint is limited by the natural colored sand used, resulting in a restricted variety of colors and the ability to mimic only about 85% of natural stone realism. For stones with intricate patterns, real stone paint can only approximate the color and texture, falling short in fully replicating the patterns.

- Water-in-Sand Coatings: These coatings contain water-based colored sand particles that can be custom-colored, allowing for a broader range of stone types to be imitated. With rich, vibrant colors and significantly enhanced realism, water-in-sand coatings achieve over 98% accuracy in replicating natural stone, offering highly authentic layering and patterning.

Crack Resistance

- Real Stone Paint: The low emulsion content, typically below 15%, results in a rigid film after drying, leading to poor crack resistance.

- Water-in-Sand Coatings: With an emulsion content around 30%, the resulting film is more flexible, providing enhanced crack resistance.

Air Permeability

- Real Stone Paint: While it offers some air permeability due to its sand-textured formulation, the low emulsion content means that the colored sand particles do not form an effective film, increasing the risk of water seepage.

- Water-in-Sand Coatings: These coatings also provide air permeability, but with smaller, more consistent sand particles, they form a uniform film that is both breathable and water-resistant.

Stain Resistance

- Real Stone Paint: The rough surface and low emulsion content make it easy for dust to penetrate and accumulate within the coating, making cleaning difficult.

- Water-in-Sand Coatings: The emulsion fully encapsulates the colored sand particles, forming an effective film that prevents dust from penetrating, allowing it to be easily washed away by rain.

Keytec's Commitment to Innovation

For many years, Keytec has been a leader in the colorants industry. Through collaboration with emulsion and protective adhesive manufacturers and extensive research and testing, Keytec has developed water-based colorants specifically designed for multi-color paints. The following are key tests conducted during this development:

1. Storage Stability Test

After blending Keytec's water-based colorants for multi-color paint into a continuous phase system, the viscosity remained stable with no fluctuations. The granulation process also showed stable particle states, with no signs of collapse or softening.

2. Anti-Bleeding Test

• Keytec Y2041 in Multi-color Paint: The blended paint exhibited no color migration, no thickening, and maintained its normal condition, demonstrating an anti-bleeding effect comparable to competing products.

• Keytec R4101 in Multi-color Paint: Similarly, the blended paint showed no color migration or thickening, outperforming competing products where protective adhesives failed to resist bleeding.

3. Storage Stability Test

In a critical test involving the Storage Effect After Mixing Three Colors, Keytec's products demonstrated exceptional stability over a two-month testing period. The product maintained its anti-bleeding properties and viscosity, with no signs of bleeding or thickening observed. This stability ensures that the colorant remains consistent and reliable during storage, contributing to its overall performance in exterior wall applications.

Conclusion

Keytec's water-based colorants for multi-color paint offers high tinting strength, excellent weather resistance, and environmental safety. It also boasts superior compatibility with most base paints used in multi-color systems available on the market. In terms of anti-bleeding performance, Keytec's colorants stands out in multi-color applications, meeting the demanding requirements for exterior wall decoration.
