PU Resins
I. Product Overview
PU resins, or polyurethane resins, are made from the reaction of isocyanates and polyols. Available in solvent-based, water-based and other types, they feature good flexibility and adhesion, and are commonly used in coatings, adhesives and other fields.
II. Key Features
· Adjustable performance: Hardness (Shore A 30-90) and elasticity can be adjusted via formulations to meet diverse needs.
· Strong adhesion: Firmly bonds with substrates such as leather, fabrics and metals.
· Good weather resistance: Anti-aging, resistant to high and low temperatures, with strong environmental adaptability.
III. Common Specifications
· Types: Solvent-based (fast-drying, suitable for industrial coatings), water-based (environmentally friendly, used for fabric treatment).
· Solid content: 30%-70% (40%-60% for coatings, 50%-70% for adhesives).
· Viscosity: 500-5000mPa・s (adjusted according to application methods such as spraying, scratching and coating).
· Storage period: 6-12 months (sealed and protected from light, below 25℃).
IV. Typical Applications
· Leather finishing (shoe uppers, luggage leather), fabric coating (waterproof fabrics).
· Adhesives (shoe material lamination, automotive interior bonding).
· Coatings (furniture paint, industrial protective coatings)
