AI Technical Summary
Traditional strontium chromium yellow primers have excessive chromium content during use, leading to environmental pollution. While they offer better rust prevention than non-complexed white primers, they are less environmentally friendly.
Made from special polyester resin, nano barium sulfate and epoxy phosphate, etc., it forms a dense paint film through chemical bonding, which improves adhesion and rust prevention. At the same time, it does not contain heavy metal chromium and has excellent environmental performance.
The resulting paint film has good adhesion, rust prevention and flexibility, and is suitable for coating building steel and household appliances. It does not pollute the environment, has wide applicability and is suitable for large-scale production.
