  • Powder coating

INFRALIT EP 8027-00 is a powder coating based on epoxy resin, which at elevated temperatures melts, cures and forms the final paint film.

Used for product coating within the metal industry, e.g. for lighting fixtures, apparatuses, furniture, shop outfittings, agricultural and household appliances. Also suitable for use on many special areas in the heavy metal and chemical industry. The resultant paint film has excellent mechanical properties, i.e. good abrasion and impact resistance and elasticity. It is not scratched easily and withstands action by acids, alkalis, greases and solvents. Its anticorrosive properties are also good. On outdoor exposure the paint film has a tendency towards chalking. This phenomenon, however, affects only the appearance, not the protective power. An alternative material for outdoor use is INFRALIT Polyester Powder, which chalks only very little.

Surface preparation

Remove all grease and dirt with care. Mere degreasing can be done e.g. by trichloroethylene vapour bath or alkali wash. Blast-clean or etch and phosphate rusty and mill-scaled surfaces. The profile of the blast-cleaned surface must be at least medium (reference comparator "G"). See standard ISO 8503-2 (G). COLD-ROLLED SURFACES: Degrease by trichloroethylene vapour bath or alkali wash. Application by electrostatic spraying to a film thickness of 80 - 150 µm. ALUMINIUM SURFACES: Degrease by e.g. alkali wash. Surfaces to be exposed to severe atmospheric conditions should also be chromated. HOT-DIP-GALVANIZED AND ZINC-ELECTROPLATED SURFACES: Remove grease, dirt and white rust by e.g. alkali wash. Depending on exposure conditions, chromating or alternatively a suitable chemical pretreatment is also required. Remove grease and white rust by e.g. alkali wash. Depending on exposure conditions, zinc phosphating or chromating is also required. HOT-ROLLED SURFACES AND CASTINGS: Remove grease and dirt. Blast-clean at least to grade Sa 2½ (ISO 8501-1). The surface profile at least medium (G) ISO 8503-2. Remove the dust. Blast-cleaning is also recommended for other surfaces, such as cast iron, whenever it is practicable, since it provides an excellent adhesion for epoxy powder.

Application

Application by electrostatic spraying to a film thickness of 80 - 150 µm.

Safety markings See safety data sheet. In order to avoid the discharge of powder from the booth into adjacent working spaces, the speed of air flow in the apertures of the booth must not fall below 0.5 m/s. Spray painters should wear dust masks and protective gloves. Any spatter of powder on the skin should be washed off with water and soap.
