A static dissipative powder coating, ECP 534 is based on a carboxylated polyester resin modified with epoxies. Designed where the user requires electrostatic dissipative properties in addition to a superior decorative finish, e.g. static safe work benches, racks , trolleys etc.. It offers excellent flow, toughness and good chemical resistance. A range of substrates may be coated.
Powder Properties:
A thermosetting powder coating based on selected solid polyester resins crosslinked with an epoxy curing system.
Specific Gravity – 1.90 g/cm3 .
Coverage – From 10 – 14 m2/kg at 60 microns film thickness.
Curing Schedule
Normal Cure:
6 minutes at 200ºC (Object Temperature)
10 minutes at 180°C (Object Temperature)
20 minutes at 160°C (Object Temperature)
Note: to achieve matt finishes, the high temperature schedule is generally required.
Technical Properties
General
All tests carried out on degreased zinc-phosphated steel coated at 70mm and cured at 10 minute @ 180°C object temperature.
