Coating passes Chinese cable tray tests

Plascoat reports that it is looking to establish one of its thermoplastic coatings as the international thick film corrosion protection coating for electrical cable trays, ladders and support systems after winning over the Chinese in an extensive series of testing applications.

According to Plascoat its versatile PPA571 has been establishing an impressive track record in the high humidity and salt-laden air of Hong Kong, with Universal Channels – Plascoat's Hong Kong-based distributor – securing prestigious water, drainage and sewage treatment, bridge and food processing applications.

The Chinese are said to have been delighted with the major corrosion protection benefits offered by PPA571 over traditional cable tray coatings at locations ranging from the Dragonair Building at the new Chek Lap Lok Airport to the Tsing Yi bridge.

Richard Loeke, Plascoat's business development manager in the region, explains: "The halogen-free nature of the coating, low toxicity and smoke levels in the event of fire have proven key in securing internal applications, while excellent resistance to UV rays and salt attack have won over specifiers for external projects".

Plascoat's drive to establish PPA571 as the standard finish in the international cable tray manufacturing sector has reportedly been aided by its total protection policy. A simple system for putting the final, all-important on-site touches to cable tray corrosion protection has been devised – allowing the covering of profiles of bare steel exposed by site cutting and the repair of any other damage caused to the pre-coating during tray installation.

The Plascoat system is explained as involving the use of rods of complementary PPA571 material being held over the exposed area of metalwork and being blended in using a standard hot air gun. The self-adhesive nature of PPA571 is said to mean that edge sealing can be carried out in seconds, preventing the traditional problem of corrosion creepage.

Applied by fluidised bed dipping or electrostatic spraying to the cleaned steel in a single shot, without the need for a primer, the coating's other properties are said to include excellent resistance to pollutants, chemicals, impact and abrasion damage.
