Polyurethane Polymer Blend

  • Polymers
  • CAS unknown
  • IUPAC: unknown (trade secret)

Polyurethane Polymer Blend (CAS unknown) appears in 1 of the 2,122 car-care products CarCareTruth tracks (as of August 2026).

No GHS health hazard classification attributed to this component specifically; the mixture's only hazard classification (Skin Sensitizer 1A) is not attributed to this ingredient by name in the SDS. Present at 10-30% by weight, the largest single non-water component of the clear-coat wipe formula.

Polyurethane polymer blend is the primary film-forming resin in the 3M Quick Headlight Clear Coat wipe formula, present at 10-30% by weight and withheld as a trade secret in the product's Safety Data Sheet. Waterborne polyurethane dispersions like this one are the workhorse chemistry behind most wipe-on and spray-on automotive clear coats: they dry to a flexible, UV-resistant film that bonds to a freshly sanded polycarbonate lens surface, sealing the abraded surface against oxygen and moisture that would otherwise resume the yellowing process.

No component-specific hazard data is disclosed for this ingredient; the SDS attributes the mixture's sole hazard classification (skin sensitization) to the formula as a whole without pinpointing a driver ingredient by name.

Health and environment notes translate the manufacturer Safety Data Sheet, the GHS classification, and authoritative regulatory listings (California Prop 65, EPA). Not medical advice. They describe the ingredient itself; whether a hazard applies to a finished product depends on its concentration and how it's used.
