Powder coatings are the fastest growing segment in coatings industry due to its top quality performance which can be achived by environmentally acceptable method with the lowest film cost Powder coatings are completly solid materials and do not includes solvents. Electrostatic spray equipments charges powder particles, these particles cover the grounded materials to be coated. Then, curingsection starts in an oven (normally 120 - 200 C). In this process, first melting starts then flows and react to form a smooth finish. Powder Coatings Can be used either protective/decorative or only protective purposes. The Most significant advantages of powders to solvent-based coatings :
• Onyle one coat system: One single layer provides all needs for protection and decorative effect.
• Economic: High yield for usage can be achived as up to 98% instead of max 55-60% of solvent based coatings.
• No solvents: It means, less hazard, less air polution, less effect on environment and operators.
• High performance: Gives very high performance against both for chemical and mechanical tests.
• Ready to use: No need to do further work.
• Specialities: All kind of special effects possible in very wide range of color and gloss variations.
• Easy to recover: Easily recovered 100% solid meterial which can be use again in fresh powder
