SilcoTek's chemical vapor deposition (CVD) coating process is unlike any other, but it is especially unique because of its environmentally friendly nature. There are two byproducts from this process: water and sand.

Each coating's composition can be found on their data sheets.

SilcoTek Compliance Statements and Coating Certifications

SilcoTek's official RoHS and REACH compliance along with SDS exemption statements are listed below along with coating certifications from relevant internationally-recognized agencies:

Safety Data Sheet (SDS) Exemption

SilcoTek^® does not provide SDSs for our coatings as they are not hazardous chemical products. 

SilcoTek’s state-of-the-art CVD processes deposit a thin (0.0005um – 2um) ceramic layer bonded to a customer’s substrate. The layer is comprised of elemental combinations of silicon, oxygen, and carbon, with no CFCs or other toxic chemicals.

Restriction of Hazardous Substances Directive 2015/863/EU (RoHS 3)

SilcoTek^® coatings do not contain any of the following compounds at levels exceeding RoHS compliance limits: Cadmium; Mercury; Lead; Hexavalent Chromium; Polybrominated Biphenyls (PBB); Polybrominated Diphenyl Ethers (PBDE); Bis(2-Ethylhexyl) phthalate (DEHP); Benzyl Butyl Phthalate (BBP); Dibutyl Phthalate (DBP); and Diisobutyl Phthalate (DIBP).

SilcoTek^® does not manufacture electrical/electronic products, devices, or equipment and is not required to CE-mark any outgoing shipments.

Registration, Evaluation, Authorization, and Restriction of Chemicals - Substances of Very High Concern (REACH-SVHC)

SilcoTek coatings do not contain any of the 247 REACH Substances of Very High Concern (SVHC) as updated by the European Chemicals Agency (ECHA) under the provisions of Regulation (EC) No. 1907/2006 of the European Parliament and of the council concerning the Registration, Evaluation, Authorization, and Restriction of Chemicals (REACH) per the ECHA 21-January-2025 and previous updates.

SilcoTek coatings do not contain any of the five PBT chemicals under TSCA section 6(h).  As stated on the United States Environmental Protection Agency Website the five PBT chemicals include: Decabromodiphenyl ether (DecaBDE), Phenol, Isopropylated Phosphate (3:1) (PIP (3:1), 2,4,6-Tris(tert-butyl)phenol (2,4,6-TTBP), Hexachlorobutadiene (HCBD), and Pentachlorothiophenol (PCTP).

Minimization of Transmission of Transmissible Spongiform Encephalopathy (TSE) and Bovine Spongiform Encephalopathy (BSE)

SilcoTek does not use materials of animal origin in SilcoTek processes. In addition, SilcoTek coating services are all at temperatures above 250 degrees Celsius, which further reduces risk of any TSE or BSE contaminations. SilcoTek packaging of customer parts is able to be specified to further avoid any risk.

Latex

SilcoTek does not use latex materials. Gloves used by employees are nitrile-based. SilcoTek standard packaging of customer parts does not use latex.
