PU-99 Aliphatic Polyurethane Dispersion represents a high-performance aqueous solution specifically engineered for professional leather finishing applications. This anionic, water-based dispersion appears as an opalescent liquid and forms a clear, elastic film upon drying, offering excellent film formation characteristics. With a solid content of 12±1% and maintaining pH stability between 7.0-8.0, this product ensures consistent performance and ease of integration into existing finishing systems. Designed primarily as a polishing base coat, it effectively levels penetration on both full grain and grain leathers, creating an ideal foundation for subsequent finishing layers. The non-dangerous classification and straightforward storage requirements between +5°C and 40°C make it a practical choice for industrial environments while maintaining product integrity over time.

This dispersion serves multiple leather manufacturing sectors including tanneries, footwear producers, automotive interior suppliers, and luxury goods manufacturers. In automotive upholstery applications, it provides the essential base preparation needed for high-end vehicle interiors where consistency and durability are paramount. Footwear manufacturers rely on its leveling properties to create uniform surfaces on premium shoes and boots, while furniture producers utilize it for upholstery leather that requires both aesthetic appeal and long-term performance. The product's versatility extends to various leather types including those used in luggage, accessories, and specialized industrial applications where surface quality and finish consistency determine the final product value.

The business value of PU-99 lies in its reliability and quality enhancement capabilities that directly impact manufacturing efficiency and end-product performance. By providing consistent leveling and penetration control, manufacturers can significantly reduce waste and rework, leading to higher yields of first-quality leather and improved production economics. The product's recommendation for bottom coats translates into end-products with enhanced durability, abrasion resistance, and longevity, creating tangible value for both manufacturers and their customers. Operational benefits include easier handling due to its water-based formulation, environmental compliance advantages, and straightforward storage conditions that simplify inventory management. These combined factors make PU-99 a dependable component that supports quality consistency and manufacturing reliability in competitive leather goods markets.
