Epoxy

General introduction
This type of coating is prepa red from the epoxy resin, and it has excellent chemical resistance and good mechanical prope rties. It is suiltable for the coating of metallic appliances that has rigor demand on the anti-corrosion , insulating properties and flexibility. It is suggested to use this type of coating directly in the coating for outdoor appliances.
