We created diversity color that is hard to express in the existing Teflon.
It does not scratch easily and highly washable coating because of the non-stickiness, the cleaning property is also better.
It is a combination with inorganic ceramic for superior heat resistance and abrasion resistance.
OCR coating has the advantage of a Teflon coating and is highly functional It's an environmentally friendly coatings, PFOA Free, PFOS Free, Heavy metals Free.
Darong cooperates with a well-known international testing institution(SGS), to ensure that products and services comply with global standards and local regulations, and we can tell you or your end clients. It is proved that the OCR coatings are in line with domestic and international standards and specifications.
