ECP 534 Static Dissipative Powder Coating

 ECP 534 is a static dissipative powder coating based on a carboxylated polyester resin modified with epoxies.  Designed where the user requires anti static electrostatic dissipative properties in addition to a superior decorative finish eg, static safe work benches, racks, trolleys etc, it offers excellent flow, toughness and good chemical resistance.  A range of substrates may be coated.  Used in the electronics industry where ESD (electro static discharge) is to be avoided.

Powder properties

A thermosetting powder coating based on selected solid polyester resins cross linked 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 200⁰C (object temperature)
• 10 minutes at 180⁰C (object temperature)
• 20 minutes at 160⁰C (object temperature)

To achieve matt finishes the high temperature schedule is generally required.

Technical Properties

All tests have been carried out on degreased zinc-phosphated steel coated at 70μm and cured at 10 minutes at 180⁰C object temperature.
