What are the anti-UV stabilizers in powder-coated wrought iron outdoor trash cans?

Powder-coated wrought iron outdoor trash cans rely on specialized anti-UV stabilizers integrated into the coating formulation to resist sun-induced degradation. These stabilizers primarily include Hindered Amine Light Stabilizers (HALS), which scavenge free radicals generated by UV exposure, preventing polymer breakdown and gloss loss. Additionally, UV absorbers (e.g., benzotriazoles) are added to absorb harmful radiation and convert it into harmless heat. For wrought iron substrates, powder coatings may also incorporate pigments like titanium dioxide for inherent UV reflection. Together, these additives inhibit fading, chalking, and structural weakening, ensuring the trash cans maintain aesthetic appeal and durability in harsh outdoor environments. The effectiveness depends on the concentration and synergy of these stabilizers within the thermoset polymer matrix.
