Heavy duty grades of Plascoat's PPA571 thermoplastic coating – said to be ideal for corrosion protection of pipes and fittings applications in the water and aqueous chemicals industries – have been launched.

Plascoat reports that PPA571H for fluidised bed dipping and PPA571HES for electrostatic spraying have been developed with a higher melt viscosity than standard PPA571, giving the formulations the higher resilience sometimes required by coaters handling thicker metal sections of more than 5nm.

The company informs us that a 30 per cent improvement in impact strength translates into improved resistance to chipping by stones, heavy or sharp metal objects, while both versions offer an impressive elongation to break point of 500 per cent and an extended temperature range that makes the coatings suitable for the harshest of conditions.

The Plascoat PPA571 series is now made up of standard PPA571 and PPA571ES,and the new PPA571H and PPA571HES, each a polyolefin based alloy applied in a single shot without the need for a primer, providing – it is claimed– excellent long-term adhesion. Other properties are said to include an excellent resistance to pollutants.

According to Plascoat, in water industry applications, PPA571 has already proven a performance and aesthetics edge over Fusion Bonded Epoxy and a significant cost advantage of up to 50 per cent over nylon.

The new PPA571 options, it is believed, will mean even greater cost-saving opportunities for coaters serving the water industry. Stated to be in receipt of EC approval and the specific support of the German, UK and Belgian control agencies, Plascoat recently won approval from the highly influential DWI for the electrostatic spray (ES) version of PPA571.
