Common powder coating materials include Epoxy Powder Coating, Epoxy Polyester Powder Coating & Polyester Powder Coating. There are various sub grades of these materials available for different industries such as Architectural, Automotive and Rail industries. The range of coating materials available means the cost of coating can be tailored to suit your project needs.
The powder coating process involves spraying electrostatically charged particles of powder around a substrate (component) which is earthed via its hanging point. At this point the particles of powder are held on to the substrate (component) purely by the induced (electrostatic) charge.
Both component and powder are then stoved in accordance with best practice and the powder manufacturers’ technical guidelines, ensuring full cure is achieved (chemically cross links). This irreversible change results in a smooth attractive durable finish.
To give our customers full confidence in our abilities to carry out these processes robustly, our systems are regularly verified by leading powder manufacturers. This is demonstrated through our Akzo Nobel ‘Service First’ approval and Plascoat Systems Approval.
The performance of any coating depends upon the pre-treatment specified and all coatings should be considered as part of a ‘coating system’. Pre-treatments include abrasive blasting (grit blast, sand blast, shot blast), conversion coatings (zinc phosphate, zirconium phosphate, iron phosphate, tri-cationic phosphate) & primer coats (zinc rich polyester, epoxy barrier primer, E-coat or Electrophoretic Coating). Plastic Coatings Ltd are able to offer all of these treatments and more as in-house services and therefore can tailor a process to suit your technical requirements whilst providing a cost effective solution.
Coating performance is often measured in Salt Spray Resistance hours. Expected performance of a basic powder coat system could be upwards from 100 hours to well over 1000 hours where a comprehensive pre-treatment has been carried out.
Other Benefits Of Using PCL
Further to the treatments mentioned here, we also have in-house coating stripping facilities. This means that we can often support your coating refurbishment requirements too (the success of this process is subject to the condition of the parts requiring treatment / refurb).
