Amine-Functional Alkoxysilane

  • Silicones
  • CAS proprietary

Amine-Functional Alkoxysilane (CAS proprietary) appears in 2 of the 2,122 car-care products CarCareTruth tracks (as of August 2026).

SDS §3 lists this ingredient's own hazard statement as 'Not classified' at the ingredient level. The mixture-level H302 (harmful if swallowed) and H318 (serious eye damage) classifications carried by the finished product are not attributed to either disclosed ingredient individually in the SDS - they most likely derive from the undisclosed 20-60% remainder of the formula or from whole-product testing. Treat this ingredient's own contribution to the finished product's hazard profile as unconfirmed rather than benign.

Amine-functional alkoxysilane is a reactive crosslinker used in ceramic-coating formulations: the amine group provides chemical affinity for hydroxyl and carbonyl sites on automotive clear coat, while the alkoxysilane group hydrolyzes and condenses into the cured Si-O-Si network alongside a siloxane carrier (in this product, decamethylcyclopentasiloxane/D5). The manufacturer's SDS discloses this ingredient at 10-20% concentration but withholds the specific CAS number as a trade secret.

Health: The SDS lists this ingredient's own classification as "Not classified" at the ingredient level. Because the finished product SDS still classifies H302 (harmful if swallowed) and H318 (serious eye damage) at the mixture level, and neither disclosed ingredient individually carries those codes, the mixture-level hazard most plausibly traces to the roughly 20-60% of the formula the SDS does not itemize by name. This gap is disclosed as an SDS transparency limitation, not resolved.

Environment: No SDS §12 ecotoxicity, persistence, or bioaccumulation data is available for this specific ingredient. The flags above default to unconfirmed (not affirmatively benign) given the absence of test data.

Purpose: Reactive crosslinker; the amine-functional group anchors the coating to clear-coat hydroxyl sites while the alkoxysilane group condenses into the cured film network alongside the decamethylcyclopentasiloxane (D5) carrier. Present at 10-20% in Clean By Pan 3 Year Ceramic and 20-30% in Clean By Pan 8 Year Ceramic (the higher reactive-crosslinker concentration is the disclosed formulation difference between the two durability tiers; both SDSs otherwise share the same D5 carrier, hazard classification, and physical properties). CAS number is trade secret in the SDS for both products.

Common questions about Amine-Functional Alkoxysilane

What is Amine-Functional Alkoxysilane used for in car care?
