Overview
Copper door finish varnish is a professional protective coating specially developed for the substrate characteristics of copper plates. The product is developed using water-borne fluororesin with excellent properties as a base material and adding additives to enhance adhesion, high hardness and scratch resistance to ensure that the product plays an anti-corrosion and ultra-weather resistant role after coating.

Copper Door Varnish (Fluorocarbon Waterborne Coating) is a refrigerant/chemical product. It is widely used in refrigeration equipment such as refrigerators, freezers, water dispensers, automotive air conditioners, central air conditioning, dehumidifiers, cold storage and commercial refrigeration, as well as in aerosol propellants, blowing agents, fire-extinguishing and cleaning applications. See the product page for details.
Copper Door Varnish (Fluorocarbon Waterborne Coating) is used as a common working fluid in refrigeration, air-conditioning and industrial applications. When replacing or retrofitting a system, qualified personnel should perform the work, paying attention to system compatibility and lubricant matching, and following relevant safety standards.
Store in a cool, dry, well-ventilated warehouse away from fire, heat sources and direct sunlight. Cylinders should be placed upright and protected from falling. Transport according to regulations for high-pressure gases or hazardous chemicals, with careful handling to avoid damage to cylinders and valves.
Ensure adequate ventilation at the workplace. Avoid direct skin contact with liquid refrigerant (risk of frostbite). Keep away from open flames and high heat. Use dedicated tools and protective equipment. In case of leakage, evacuate, ventilate and contact professionals.
The exact Ozone Depletion Potential (ODP) and Global Warming Potential (GWP) are listed in the Physical Properties table on the product page. Select refrigerants considering energy efficiency, safety and environmental impact.
Multiple package sizes are available (e.g., cylinders, drum or ton packages - see product page). Bulk orders are supported. Contact sales for the latest quote and lead time.
