Polymer UV Stabilizers for Automotive Components
UV radiation from sunlight can cause degradation of automotive surfaces and materials, leading to fading, cracking, and reduced lifespan. TINTOLL UV absorbers for coatings are incorporated into automotive paints, coatings, and plastics to absorb and dissipate harmful UV radiation, preventing damage. Photoinitiators are added to coating formulations, and upon exposure to UV light, they trigger a chemical reaction that leads to rapid curing.
