What protective coatings prevent yellowing in white polyethylene outdoor sculptures?

White polyethylene outdoor sculptures are popular for their durability and aesthetic appeal, but they often face the issue of yellowing due to prolonged exposure to sunlight and environmental factors. To maintain their pristine appearance, applying the right protective coatings is essential.

1. UV-Resistant Clear Coatings: These coatings block harmful ultraviolet rays, the primary cause of yellowing in polyethylene. Look for formulations specifically designed for plastics.

2. Acrylic-Based Sealants: Acrylic coatings provide a protective barrier against oxidation and UV damage while maintaining the sculpture's original color.

3. Polyurethane Coatings: Durable and weather-resistant, polyurethane coatings offer long-term protection against yellowing and environmental wear.

4. Specialized Plastic Sealers: Products like Krylon UV-Resistant Clear Coat or Rust-Oleum Plastic Paint are tailored for polyethylene and prevent discoloration.

For best results, clean the sculpture thoroughly before application and reapply the coating every 1-2 years, depending on exposure. By using these protective measures, your white polyethylene sculptures can remain vibrant and yellow-free for years.
