UV Absorber PR25

Product Overview

UV Absorber PR25, chemically known as Dimethyl 2-[(4-methoxyphenyl)methylidene]propanedioate, represents a premium class of ultraviolet stabilizers engineered for high-performance polymer and coating applications. As a specialized organic compound, it provides robust protection against UVB radiation, ensuring the longevity and aesthetic integrity of materials exposed to harsh environmental conditions. Our manufacturing process adheres to strict quality control standards, delivering a product with exceptional purity and consistent performance batch after batch.

This additive is particularly valued in industries where color neutrality is critical. Unlike many conventional stabilizers, PR25 maintains clarity even at higher concentrations within resin systems. It does not induce discoloration over time and resists forming colored complexes with metal ions, making it an ideal choice for clear coats and transparent plastic components.

Key Features and Benefits

• Superior UVB Absorption: Provides targeted protection in the UVB range, effectively shielding substrates from photodegradation.
• Excellent Color Stability: Remains colorless in formulation and prevents yellowing or haze development in the final product.
• Metal Ion Compatibility: Does not form colored complexes with metal ions, ensuring compatibility with various catalytic systems.
• Thermal Stability: Demonstrates reliable performance during processing, with a defined melting point suitable for standard industrial extrusion and coating processes.
• Versatile Compatibility: Works effectively across a wide range of polymer matrices including PVC, polyesters, and polycarbonates.

Technical Specifications

Industrial Applications

UV Absorber PR25 is extensively utilized in solvent-borne coatings and general industrial finishing systems. It is particularly recommended for UV-cured systems and clear coats where maintaining optical clarity is essential. Beyond coatings, this stabilizer is compatible with rigid PVC materials, polyesters, polycarbonates, polyamides, styrene plastics, EVA copolymers, and cellulosics. Its ability to protect without compromising visual properties makes it a preferred choice for automotive coatings, architectural finishes, and high-end plastic consumer goods.

Storage and Handling

To maintain optimal quality, containers should be kept tightly closed in a cool, dry environment. Avoid exposure to direct sunlight or moisture during storage. The product is typically packaged in 25kg cartons or drums, with palletized options available for bulk orders. Our logistics team ensures secure handling to preserve the integrity of the crystalline powder during transit.
