In the high-end coating market, where aesthetic appeal and tactile experience are paramount, Anti-fingerprint (AF) performance has become a critical benchmark for product value. Whether it is premium matte wood furniture that showcases natural textures or 3C electronic devices seeking a high-tech aesthetic, surface residues like sweat and oil not only compromise beauty but also reduce the durability of the coating.

RK-Chem’s flagship product, RS-5613 Functional Anti-Fingerprint Additive, is engineered to solve these industry pain points. With superior oleophobic properties and extreme wear resistance, it is the ideal solution for water-based wood topcoats and 3C protective varnishes.

1. Industry Pain Points: The "Invisible Killers" of Surfaces

• The "Oily Shine" on Matte Wood: Matte surfaces are prized for their sophisticated texture, but their micro-porous structure easily traps skin oils. These oil spots create unsightly glossy patches at certain angles, are difficult to clean, and can lead to yellowing or film degradation over time.

• The "High-Frequency Touch" Challenge for 3C Devices: Protective varnishes for smartphones and tablets must withstand constant fingertip friction. Standard hydrophobic agents often fail to balance oleophobicity with long-term durability, causing the anti-fouling effect to vanish after short-term use.

2. Core Technical Advantages of RS-5613

RS-5613 is an advanced functional coating based on Ethane-based perfluorobutane isobutyl ether modified monofluorosilane. Its unique fluorocarbon chain structure provides performance far exceeding traditional silicone oils.

• Extreme Hydrophobicity & Oleophobicity (Dual-Repellency): After curing, the initial water contact angle exceeds 110 degrees. It effectively prevents oils and sweat from wetting or spreading across the surface, making fingerprints remarkably easy to wipe away.

• Superior Abrasion & Friction Resistance: Designed for high-intensity 3C usage, RS-5613 demonstrates incredible durability. In steel wool friction tests (1000g load), it maintains a water contact angle above 100 degrees even after 2,500 cycles, with no film peeling.

• Low Dynamic Friction Coefficient: Beyond anti-fingerprint effects, it imparts a "Slippery Feel" to the film. By reducing surface friction, it significantly enhances the scratch resistance of the coating.

• Excellent Chemical Stability: It possesses outstanding acid and alkali resistance, ensuring that anti-fouling performance remains stable even when exposed to complex chemical environments.

3. Application Guidelines and Technical Tips

To ensure RS-5613 delivers optimal results in water-based wood and 3C varnish systems, precise application is required:

1. Surface Pre-treatment: Surfaces must be thoroughly cleaned of moisture, grease, and dust. For precision 3C components, Plasma Treatment is recommended to maximize the adhesion of the AF layer.

2. Strict Environmental Control: Direct skin contact with the substrate is strictly prohibited during the process; finger oils can cause significant film defects.

3. Precise Curing Process: The recommended baking condition is 170°C - 180°C for 30 minutes. This is crucial for the functional fluorosilane molecules to form a robust chemical cross-link with the resin matrix.

4. Storage Requirements: RS-5613 is sensitive to humidity. It must be stored in a cool, dry environment (below 20°C and under 55% humidity) in a sealed container.

4. Conclusion

RS-5613 is more than a simple additive; it is a comprehensive surface defense solution for premium coatings. By pushing the limits of oleophobicity and wear resistance, RK-Chem empowers coating manufacturers to create long-lasting, anti-fouling products that stand out in the global market.
