  • UV stabilizers
  • CAS 104810-48-2

Polymeric Benzotriazole UV Absorber (CAS 104810-48-2) (CAS 104810-48-2) appears in 1 of the 1,812 car-care products CarCareTruth tracks (as of June 2026).

Low acute toxicity at the sub-0.15% concentrations found in consumer vinyl protectant formulations. No GHS health hazard classification at product mixture level from this ingredient alone. Used in automotive coating systems and industrial UV-stabilizer packages.

Polymeric benzotriazole (CAS 104810-48-2) is a high-molecular-weight UV absorber used in automotive coatings, clear coats, and vinyl protection formulas. The polymeric structure provides improved durability and reduced volatility compared to low-molecular-weight benzotriazole UV absorbers. It absorbs UV radiation in the 300–385 nm range and converts it to heat, preventing photodegradation of the substrate.

Meguiar's discloses this ingredient alongside CAS 104810-47-1 in their G-series consumer vinyl protectants as part of their "UV Clear Coat Technology" UV stabilizer package. Concentrations are below 0.15% in these formulations. The same CAS pair appears in Meguiar's G15812 Ultimate Black Plastic Restorer, confirming it as a standard Meguiar's G-series UV stabilizer package.
