Excellent abrasion resistance and salt water resistance.
It can prompt suitable temperature by the way the pattern appears when cooking.
Good thermal conductivity，Can heat up quickly in a short time by adding Graphene inside, Graphene also makes the coating performance more stable and has sterilizing effect.
For health and environmental protection, PFOA-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 Grafino Coating coatings are in line with domestic and international standards and specifications.
