SEAPUR 50G72 Solvent-Free Water-Based Self-Matting Polyurethane: Defining Minimalist Matte Aesthetics for Flexible Substrates

——Zero Solvent, Yellowing Resistance, Exceptional Leveling, Infusing High-End Matte Essence into Paper, Leather, Textiles and Wood

In the coatings and finishing industry, “matting” often means introducing micron-sized powders into the system or increasing VOC emissions. However, the launch of SEAPUR 50G72 by Xidun New Materials—a solvent-free water-based self-matting aliphatic polyurethane—with its unique molecular design, completely eliminates the need for external matting powders while raising environmental standards to new heights. It is specifically designed for substrates with stringent flexibility requirements such as paper, leather, textiles and wood, redefining the dual realms of visual and tactile experiences with “smooth hand feel” and “low gloss”.

No Matting Powder Required, Inherent Matte DNA

SEAPUR 50G72 possesses excellent matting properties, achieving a uniform and long-lasting low-gloss finish through its unique phase separation structure. By eliminating the addition of external matting powders, it not only completely resolves quality control headaches such as powder sedimentation and substandard grind fineness, but also preserves the coating’s transparency and original color saturation. This “native matte effect” makes graphics and text on printed paper clearer and the color of dyed leather more pure.

Mirror-Like Leveling, Excellence in Every Detail

Surface defects are the number one enemy of coating value. SEAPUR 50G72 exhibits outstanding leveling properties, spreading rapidly even under low shear forces to eliminate brush marks, orange peel and cratering. For textile coatings requiring seamless splicing or high-gloss wood finishes, it imparts a silky-smooth, flawless texture to the surface, making every inch of the coating stand up to close inspection under a magnifying glass.

Aliphatic Light Resistance, The Promise of Non-Yellowing

Using aliphatic isocyanates as the backbone, SEAPUR 50G72 inherently has excellent light resistance. Under prolonged UV exposure, the coating will not yellow or chalk, consistently protecting the pure beauty of light-colored leather, white paper and natural wood grain. This feature makes it the top choice for applications such as outdoor furniture, high-end leather goods and art bookbinding paper.

Outstanding Stability, Forgiving Process Window

SEAPUR 50G72 demonstrates exceptional stability both during long-term storage in one-component systems and in terms of pot life after mixing with curing agents. With a viscosity below 1500cps, it is easy to pump, spray and knife coat, and has excellent compatibility with various additives and resins, greatly reducing the difficulty of formulation adjustment and batch-to-batch variations. This is a valuable process advantage for flexible production lines requiring quick product changeovers.

Solvent-Free Formula, Lightening the Burden on Health and the Planet

SEAPUR 50G72 rejects organic solvents at the source, achieving truly solvent-free delivery. This not only means zero VOC emissions and extremely low odor, keeping construction workers away from harmful substances, but also helps end products easily pass the most stringent environmental regulations. In today’s era where dual carbon goals and ESG have become core brand values, choosing SEAPUR 50G72 is casting a vote of confidence in sustainable development.
