UV Absorber UV384-2: English Applications

1. Polymer Industry

• Plastics and Thermoplastics

• Additive in Polyolefins: Used in polyethylene (PE), polypropylene (PP), and ethylene-propylene-diene monomer (EPDM) to prevent photo-oxidation, which causes yellowing, embrittlement, and mechanical property degradation in outdoor applications (e.g., agricultural films, automotive bumpers, pipes, and packaging materials).

• Engineering Polymers: Added to polyamides (PA), polyesters (PET/PBT), and polycarbonates (PC) to stabilize components exposed to sunlight, such as automotive exterior parts, electrical connectors, and outdoor furniture.

• Synthetic Rubbers

• Protects rubber compounds (e.g., tires, seals, gaskets) from UV-induced cracking and loss of elasticity, extending service life in automotive and industrial applications.

• Fibers and Textiles

• Incorporated into polypropylene fibers (e.g., outdoor carpets, ropes, and agricultural nets) and polyester fabrics (e.g., outdoor awnings, marine textiles) to maintain colorfastness and mechanical strength under prolonged UV exposure.

2. Coatings and Paints

• Architectural and Industrial Coatings

• Formulated into water-based or solvent-based paints, varnishes, and lacquers to protect surfaces (e.g., wood, metal, concrete) from UV-induced fading, chalking, and delamination. Common applications include exterior house paints, marine coatings, and automotive OEM finishes.

• Powder Coatings

• Stabilizes polyester, epoxy, and hybrid powder coatings for outdoor use (e.g., aluminum extrusions, outdoor equipment), ensuring long-term weather resistance.

• UV-Curable Coatings

• Used in UV-cured inks and coatings (e.g., wood flooring, plastic coatings) to balance UV absorption during curing with post-cure protection against environmental UV radiation.

3. Adhesives and Sealants

• Structural Adhesives

• Added to acrylic, polyurethane, and epoxy adhesives used in outdoor bonding applications (e.g., solar panel assembly, automotive glazing, and aerospace composites) to prevent UV-induced degradation of adhesive properties.

• Sealants

• Stabilizes silicone, acrylic, and polyurethane sealants in building and construction (e.g., window frames, roofing joints) to maintain elasticity and weather resistance.

4. Automotive and Transportation

• Exterior Components

• Protects automotive plastics (e.g., bumpers, trim panels, headlamp lenses), rubber parts (e.g., tires, weather stripping), and coatings (e.g., clear coats) from UV damage, ensuring color stability and surface integrity over the vehicle’s lifetime.

• Aerospace Materials

• Used in aircraft coatings, cabin materials, and exterior composites to resist UV radiation at high altitudes, where exposure is more intense.

5. Packaging and Agriculture

• Packaging Films

• Stabilizes polyethylene (PE) and polypropylene (PP) films used for food packaging, agricultural films (e.g., greenhouses, mulch films), and stretch wraps, preventing premature degradation from sunlight.

• Agricultural Plastics

• Enhances the longevity of greenhouse films, silage wraps, and irrigation pipes by blocking UV rays that degrade polymer structures.

6. Specialty Applications

• Optical and Electronic Devices

• Used in optical films (e.g., polarizers, LCD backplanes) and electronic component coatings to prevent UV-induced yellowing or damage to sensitive materials.

• Solar Energy Systems

• Protects photovoltaic (PV) module encapsulants (e.g., ethylene-vinyl acetate (EVA) or thermoplastic polyurethane (TPU) films) and backsheets from UV degradation, maintaining efficiency over decades of outdoor exposure.

• Leather and Synthetic Leather

• Added to leather finishes and synthetic leather (e.g., automotive upholstery, outdoor furniture) to preserve color and texture under UV exposure.
