Silane Crosslinker (Proprietary, Primary)
- Ceramic (SiO₂)
- CAS proprietary
- IUPAC: Silane crosslinker (proprietary, CAS undisclosed)
Silane Crosslinker (Proprietary, Primary) (CAS proprietary) appears in 1 of the 1,812 car-care products CarCareTruth tracks (as of June 2026).
Carries H332 (Acute Tox. 4 inhalation), H319 (Eye Irritation Cat 2), and H373 (STOT RE 2) at ingredient level per SDS §3. H332 and H319 do not transfer to mixture-level SDS §2 classification. H373 is reflected at mixture level.
This ingredient is a proprietary silane crosslinker (CAS not publicly disclosed) present at 10–40% in Gtechniq EXO V4. Silane monomers are the reactive building blocks of polysilazane coating chemistry — they condense with surface silanol groups on clear coat and with other silane/siloxane molecules in the film to form the cured crosslinked network.
The H411 (Aquatic Chronic Cat 2) classification at ingredient level is the primary environmental concern for this component — it drives the ingredient-level aquatic_toxicity: true flag and contributes the −1.0 environment deduction for ingredient-level aquatic toxicity in the product's environment score. H332 (acute inhalation hazard) is an ingredient-level classification that does not appear at the mixture level in SDS §2. CAS number is not publicly disclosed by Gtechniq; classification data is derived from SDS §3 hazard codes.
