+How do I request a TDS or SDS for a specific SEMITECH product?
Submit the contact form on this page with your product name or grade number and the document type needed (TDS, SDS, or COA). SEMITECH fulfills documentation requests within 48 business hours. For urgent qualification timelines, note your application and volume in the request to prioritize the response.
+Are SEMITECH’s COA documents lot-specific or generic?
SEMITECH COA reports are issued per production lot. Each COA references the specific lot number, production date, tested parameters, specification limits and QC sign-off — meeting the traceability requirements of regulated supply chains in cosmetics, electronics and industrial coatings.
+What QC certification covers SEMITECH specialty chemicals?
SEMITECH operates under ISO 9001 certification, covering raw-material incoming inspection, in-process quality control and finished-product release testing. The certification scope includes titanate coupling agents, silicone fluids and fumed silica product lines, with documented traceability to every shipped lot.
+What BET surface area range is available for SEMITECH fumed silica grades?
SEMITECH hydrophilic fumed silica is available from 50 m²/g to 380 m²/g (±15 m²/g tolerance, measured by BET-N₂ per ISO 9277). Higher BET grades (200–380 m²/g) offer stronger thickening and reinforcement; lower BET grades (50–130 m²/g) are preferred for free-flow and anti-blocking applications.
+Which viscosity grades of silicone fluid does SEMITECH supply, and are TDS available for all of them?
SEMITECH polydimethylsiloxane (PDMS) fluids span 5 cSt to 100,000 cSt. Full TDS covering kinematic viscosity, flash point, refractive index and pour point are available for all standard grades. Reactive grades (amino-, epoxy- and vinyl-functional) include additional functional-group content data in their TDS.
+Does SEMITECH provide REACH and RoHS compliance documentation?
Yes. REACH SVHC declarations, RoHS compliance letters and TSCA inventory status letters are available on request for all product families. Request these documents through the same contact form, specifying your destination market (EU, US, or other) so the correct regulatory format is provided.
