How do artists address yellowing in clear polypropylene installations?
Artists working with clear polypropylene often face the challenge of yellowing over time due to UV exposure and oxidation. To combat this, they employ several strategies:
1. UV Stabilizers: Adding UV-resistant additives during production slows degradation.
2. Protective Coatings: Applying acrylic or polyurethane coatings shields the surface.
3. Controlled Environments: Storing installations away from direct sunlight and humidity reduces aging.
4. Material Selection: Opting for high-grade, non-recycled polypropylene minimizes impurities.
5. Regular Maintenance: Gentle cleaning with non-abrasive solutions preserves clarity.
By combining these methods, artists ensure their polypropylene works remain visually pristine for years.
