High-Transparency, High-Gloss Wax Emulsion: Empowering Water-Based Topcoat Solutions with Scratch and Abrasion Resistance

In the high-end leather goods market, consumer demands for surface finishes are becoming increasingly rigorous. They seek high-gloss visual impact and practical scratch and abrasion resistance, while also desiring a silky, refined tactile experience. Traditional wax emulsions often enhance wear resistance at the expense of transparency, leading to coating whitening and reduced gloss—factors that significantly compromise the product’s premium quality.

After years of research and development, Nanjing Tianshi has launched the OE-6303 non-ionic modified polyethylene wax emulsion. Through unique refractive index matching technology and precision wax particle design, it achieves a perfect balance of four key properties—high transparency, high gloss, scratch resistance, and superior hand-feel—offering a comprehensive solution for water-based hydroxy-acrylic leather topcoats.

OE-6303 is a non-ionic modified polyethylene wax emulsion designed specifically for high-end coating applications. Its core technical advantages are reflected in the following specifications:
Appearance: White liquid; Melting point: 124–127°C; pH value: 5–8; Ionic nature: Non-ionic (APEO-free); Solids content: 40%; Recommended dosage: 3–5%.

In-depth Analysis of Three Core Selling Points
1 High Transparency and High Gloss—Maintaining a Brilliant Finish
OE-6303 utilizes advanced refractive index matching technology, with wax particle sizes finely controlled at the micron level to closely align with the refractive index of water-based hydroxy-acrylic systems. At a dosage of 3–5%, light transmission loss in the coating is less than 5%; wood grain or natural leather pores remain clearly visible, perfectly showcasing the substrate’s natural beauty.
2 Excellent Scratch and Abrasion Resistance—Enhanced Surface Protection
As the coating dries, the OE-6303 wax particles migrate to the surface, forming a dense, protective micro-crystalline layer. Coatings containing 3–5% OE-6303 demonstrate stability without emulsion breakdown when exposed to 75% alcohol. 3. Excellent smooth feel—a silky touch

The smooth, silky feel OE-6303 imparts to coatings stems from its unique surface tension regulation mechanism. As wax particles migrate to the surface, they form a low-surface-energy structure that reduces the coating’s coefficient of friction by 40–50%, delivering the following tactile experience:
This anti-blocking wax characteristic also provides the coating with excellent resistance to blocking (sticking), effectively preventing adhesion issues during winding or stacking—making it particularly suitable for the processing, storage, and transport of leather products.

Multi-system compatibility—broad applicability
OE-6303, a non-ionic modified polyethylene wax emulsion, offers exceptional system compatibility and integrates perfectly with the following water-based coating systems:
1. Water-based hydroxyl-functional acrylic systems
OE-6303 is highly compatible with water-based hydroxyl-functional acrylics; its addition does not affect drying times or cause issues such as phase separation or flocculation, while maintaining outstanding gloss stability.
2. PU systems (polyurethane)
In polyurethane systems, OE-6303 enhances the coating’s chemical and abrasion resistance while preserving the soft, supple feel characteristic of PU.
3. UV-curing systems
For UV systems, OE-6303 undergoes special processing to ensure stability during UV curing, without compromising curing efficiency or final hardness.
4. NC systems (nitrocellulose)
OE-6303 also demonstrates excellent compatibility in NC systems, improving surface smoothness and scratch resistance. Tianshi OE-6303, a non-ionic modified polyethylene wax emulsion, offers a comprehensive technical solution for water-based hydroxy-acrylic leather topcoats, distinguished by four key advantages: high transparency, high gloss, scratch and abrasion resistance, and a smooth tactile feel. Requiring an addition rate of only 3–5% to achieve a significant overall improvement in coating performance, it is an ideal choice for the surface treatment of high-end leather products.
