Waterborne polyurethane dispersion for wood coatings WL-PU332
Water based polyurethane acrylate (PUA) provides durable, glossy, and elastic films in wood coatings and enhances adhesion, weather resistance, and UV stability in plastic coatings.
Product Introduction
WL-PU332 is a solvent-free aliphatic polyurethane acrylic copolymer dispersion specially formulated for wood and plastic coatings. It delivers a balanced combination of high hardness and flexibility, ensuring excellent surface durability and long-lasting protection. The product provides outstanding solvent, block, and imprint resistance, helping coatings maintain their smooth appearance even under pressure or heat. In addition, its excellent wetting and flow properties promote uniform film formation and superior surface leveling, resulting in a high-quality finish. These advantages make WL-PU332 ideal for use in wood coatings that require clarity, toughness, and resistance to everyday wear, as well as in plastic coatings that demand strong adhesion, chemical resistance, and stable performance under various environmental conditions.

Storage and remarks
In originally closed containers WL-PU332 are stable when stored at 20℃ for 6 months after delivery date. The recommended temperature range is 5~30℃. Freezing or storage at higher temperature than 30℃, can affect the viscosity or the average particle size and finally lead to a sedimentation or coagulation. A contamination with bacteria, fungi or algae can damage the product irreversibly
