Properties
Within our range of metallic coated products, Easyfilm® is an environmentally friendly, chromate-free thin organic coating (TOC) continuously applied double-sided on the whole range of electrogalvanised steel, hot dip galvanised steel, galfan, Alusi® and Alupur®. Easyfilm® complies with current European legislation banning the use of hazardous substances such as hexavalent chromium, specifically the Restriction of the Use of Certain Hazardous Substances in Electrical and Electronic Equipment and the End-of-Life Vehicles directives.
Advantages
Easyfilm® has a dry appearance. Its essential role is to:
- Keep the metallic coating corrosion-free for six months (starting from the date on which the product becomes available at the manufacturer's works), providing that it is properly packed, shipped, loaded and stored
- Withstand fingerprints (anti-fingerprint properties)
- Facilitate forming (possible without the use of lubricating oils)
- Allow direct painting (without pre-treatment)
Applications
The applications of Easyfilm® are extremely varied, due to the range of properties and advantages available. They include:
- Construction: profiling, roofing, cladding, structural components etc
- Domestic appliances: washing machines, dryers, dishwashers, hi-fi equipment, covers, components etc
- General industry: electrical cabinets, metal furniture, heating and ventilation, cable trays etc
