南京粉末新材料有限公司

Nanjing Powder New product is epoxy coating powders and has excellent reliability, workability and safety with good adhesive strength, heat resistance, electrical insulation and high mechanical strength. Epoxy coating powders are normally preferred if a tough durable film is required. It should not be used if the coated part is expected to be exposed to direct sunlight for long periods of time, as the coating will form a chalk-like appearance under such conditions.

Gives hard durable protective finishes with excellent adhesion and chemical resistance. Epoxy

Gives hard durable protective finishes with excellent adhesion and chemical resistance. Epoxy coating powders have good electrostatic charging properties and excellent transfer efficiency. Nanjing Powder New series is a thermosetting powder coating based on epoxy polyester resin with excellent smooth glossy and good flow-out finishes. Its outstanding over bake yellowing resistance and mechanical properties make it a wide range of indoor applications such as domestic appliances, home and office furniture, light fixtures, shelving, machinery, ceiling panels, switchboards etc. Texture finish is also available.

PRE-TREATMENT

To ensure maximum adhesion the substrate must be thoroughly clean, free from grease, oil, rust, mill scale or any other contaminant. Cleaning maybe carried out either by shot blasting, solvent or chemical degreasing. For applications where high corrosion or chemical resistance is required the substrate should be chemically treated prior to powder coating.
