"Zero Chrome" Corrosion Protection Coatings

CHEMIONIC provides ongoing consulting and laboratory services for  Elisha Technologies in the development of "Zero Chrome" corrosion protection coatings.  The results are better performance in a variety of areas, from corrosion protection to heat tolerance.  This is done by using only silicates, common sand-like minerals found in the earth's crust. No chromium. No phosphate. Just better performance without environmental or regulatory worries.

Top coat adheres well. The silicate coatings on galvanized (zinc) surfaces are already under commercialization. Silicate coating on zinc performs better than chromate and economically competitive. CHEMIONIC will provide testing of your Zn plated parts and also R&D support for any other substrate materials. 

The finish can be clear or black. We have a room temperature, environmentally friendly black oxide coating for zinc surfaces and working on other substrate materials. At this point, the black oxide coatings are used in conjunction with silicate coatings when there is need for black finish.
