Amino Dimethylsiloxane

  • Silicones
  • CAS 71750-80-6
  • IUPAC: Aminopropyl-terminated polydimethylsiloxane

Amino Dimethylsiloxane (CAS 71750-80-6) appears in 3 of the 1,812 car-care products CarCareTruth tracks (as of June 2026).

No GHS hazard classification at typical use concentrations; amino functional groups provide the reactive site for surface bonding.

Amino dimethylsiloxane is an amino-functional polydimethylsiloxane where amine groups at the polymer chain ends react with activated surface sites on paint clear coats. This reactive anchoring mechanism distinguishes it from plain PDMS (which relies on physical adsorption) and provides the basis for enhanced durability claims in polymer sealants.

The ingredient is non-volatile (very high molecular weight) and does not contribute meaningfully to VOC. No GHS health or environmental hazard classifications have been established at typical mixture concentrations.

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.
