Silane Crosslinker (Proprietary, Secondary)

  • Ceramic (SiO₂)
  • CAS proprietary
  • IUPAC: Silane crosslinker (proprietary, CAS undisclosed)

Silane Crosslinker (Proprietary, Secondary) (CAS proprietary) appears in 1 of the 1,812 car-care products CarCareTruth tracks (as of June 2026).

Carries H227 (Flam. Liq. Cat 4), H302 (Acute Tox. 4 oral), H314 (Skin Corr. 1B), and H317 (Skin Sensitizer Cat 1) at ingredient level per SDS §3. H317 transfers to mixture-level SDS §2; H227, H302, and H314 are ingredient-level only and do not appear in SDS §2 mixture classification.

This ingredient is a secondary proprietary silane crosslinker (CAS not publicly disclosed) present at 1–10% in Gtechniq EXO V4. At this concentration range it functions as a minor crosslinking contributor and adhesion promoter in the polysilazane network.

The H317 (Skin Sensitizer Cat 1) classification at ingredient level is the most consequential health classification for this component — it transfers to the mixture-level SDS §2 and drives the skin: recommended PPE tier for the product. H314 (Skin Corrosion Cat 1B) at ingredient level does NOT appear in SDS §2 mixture classification, meaning the mixture-level formulation is not classified as corrosive even though this component carries that code at ingredient concentration. CAS number is not publicly disclosed by Gtechniq; classification data is derived from SDS §3 hazard codes.
