record uk has installed a powder coating facility within its manufacturing facility in Blantyre, south of Glasgow. The plant consists of a spraying booth and curing oven. The spraying booth is equipped with a conveyor system to facilitate the consistent high quality finish record uk requires to complement the high quality of its products for its customers.
Being able to coat and finish the door frames in-house means orders can be processed and installed even quicker than before – bringing a major benefit to customers where downtime and installation times are critically important.
Powder coating is a type of coating that is applied as a free-flowing, dry powder which is then cured at a high temperature for a short period. It has many advantages over conventional liquid paint which keeps the paint in a solvent based suspension for application.
These benefits are:
• there is no carrier fluid to evaporate away or emit volatile organic compounds (VOCs)
• the process is safer
• powder coating eliminates the possibility of runs and sagging in finishes
• the resulting coating is harder and more durable
• surfaces can be coated horizontally or vertically
• Powder Coating Application Process
The powder coating is usually applied with an electrostatic gun which imparts a positive electric charge to the powder and uses compressed air to discharge the powder. The coated frame is then cured under heat – usually at 200 °C (390 °F) for 10 minutes – in order to reach full hardness and durability. When the frame is heated, the powder melts and flows to form a uniform “skin”. This skin then cools to form a hard coating. This process creates a finish that is tougher than conventional paint.
