Changfu Chemical UV Coating Special UV Reactive Diluent Type Colloidal Silica

In the UV coating industry, hardness and wear resistance have always been key indicators of product quality. However, traditional methods for improving these properties often come with significant drawbacks. For example, using high-functionality resins can increase the viscosity of the system, making application more difficult. Adding reinforcing materials such as fumed silica can also lead to poor compatibility and sedimentation issues. Drawing on its solid R&D foundation, Changfu Chemical has introduced a UV reactive diluent type nano silica sol specifically for UV coatings. This product has made significant progress in enhancing the performance of UV coatings and has provided new ideas and solutions for the development of the industry.

 

Core Advantages

Significant Performance Improvement: Changfu Chemical's UV reactive diluent type nano silica sol can significantly enhance the scratch resistance and wear resistance of the coating. This ensures that products maintain a bright and attractive appearance even in harsh usage environments. Additionally, it provides excellent barrier effects against gases, water vapor, and solvents, effectively blocking the erosion of harmful external substances and extending the service life of the coating.

Unaffected Construction Performance: Unlike traditional fillers, this UV reactive diluent type nano silica sol is a very transparent low-viscosity product. It does not increase viscosity like traditional fillers, so it does not significantly impact the processing performance of the coating during application. Whether by brush, spray, or dip coating, it can easily achieve uniform coverage and ensure construction quality.

Perfect Preservation of Transparency and Gloss: In applications where the appearance of transparent coatings is highly valued, Changfu Chemical's UV reactive diluent type nano silica sol performs exceptionally well. It does not affect the transparency or gloss of the coating, allowing the natural color of the substrate to be perfectly displayed. It is particularly suitable for wood clear coatings and plastic clear coatings (such as on PC, PMMA, PET substrates), meeting the needs of the high-end transparent coating market.

Comprehensive Performance Enhancement: In addition to the significant improvement in hardness and wear resistance, this product also offers multiple additional advantages. It can enhance weather resistance and slow down thermal aging, reduce volume shrinkage and reaction heat during curing, and decrease thermal expansion and internal stress. This improves the overall stability and service life of the coating. Moreover, it also enhances adhesion to various inorganic substrates (such as glass and aluminum), ensuring that the coating is firmly attached and less likely to peel off.
