Low Acid Value Solid Acrylic Resin SA-536

  Solid acrylic resins are widely used in UV and PU primers due to their excellent film-forming properties, adhesion-promoting effects, and compatibility with different curing systems. In UV primers, solid acrylic resins offer strong substrate adhesion, high transparency, and good surface leveling, creating an ideal base for UV topcoats to achieve high gloss, clarity, and durability. In PU primers, hydroxyl-functional solid acrylic resins react with isocyanates to form a tough, cross-linked film that combines hardness and flexibility, ensuring long-term resistance to chemicals, weathering, and mechanical stress. With their balance of adhesion, durability, and surface quality, solid acrylic resins play a key role in enhancing the performance and appearance of UV and PU-based primer systems.

Product Description

  SA-536 is a thermoplastic acrylic resin composed of MMA and n-BMA polymers, offering significant advantages in UV and PU primers. Its high gloss, strong abrasion resistance, and excellent solvent release make it an ideal choice for UV primers, ensuring smooth leveling, strong adhesion to the substrate, and a long-lasting glossy base, thereby enhancing the performance of UV topcoats. In PU primers, its strong adhesion, hardness, and stability contribute to improved intercoat bonding, scratch resistance, and long-term durability, while its low acid value enhances chemical resistance and non-yellowing properties. Overall, SA-536 provides primers with outstanding appearance, mechanical strength, and durability, making it suitable for demanding applications such as appliance paints, silver paints, and high-performance protective coatings.
