Manufacturers in Germany, the UK, France, Netherlands, Belgium and Italy are among the countries to welcome the new Plascoat PPA 684 as well as the top-of-the-range PPA 571 fluidised bed applied alternative. PPA 684 has been developed to provide greater corrosion resistance to diluted battery acid and chemicals than any polyethylenes used in the sector and to overcome the environmental concerns associated with the spraying of polyurethanes. Battery boxes in excess of a cubic metre are now being dipped in PPA 684 which is available in a range of colours. The application of PPA 684 to a typical thickness of 600-800 microns provides a smoother finish at lower temperatures at a cost around half that of a polyurethane coating.
And alternative version -
PPA 691 - has been specifically
developed to meet the hardness, electrical and chemical resistance
requirements of ATEX.

Plascoat’s new grade of thermoplastic coating,
PPA 691, has been developed for
specific use on battery boxes for electrical powered vehicles in
hazardous dusty environments where the risk of explosion from sparks
could be potentially hazardous and to meet the requirements of ATEX.
The new coating is fully resistant to chemical attack including battery
acids, offers high impact protection and excellent long-term adhesion,
preventing any metal, once coated from becoming exposed and conductive.
Nico den Broeder, Plascoat’s sales Director explains “a
resilient, durable, acid resistant coating is essential for battery
boxes where there is a potential risk of sparks if bare metal is
exposed. We have carried out extensive testing in our technical centre
to perfect a product that provides a pin-hole free, smooth but tough
finish at both higher and lower temperatures. It is also half the cost
of a polyurethane coating.”
Plascoat PPA 691, fluidised bed dipping powder,
offers excellent particle size distribution and superb flow
characteristics as well as outstanding environmental credentials - no
VOCs, no isocyanates and no heavy metals. PPA 691 is available in a wide
range of colours to RAL specification, to
compliment most electrically powered vehicles.
Like other products in the PPA
range from Plascoat, PPA691 requires no special primers when applied to
clean metal yet offers excellent and lasting adhesion on the metal
surface and improved coating performance on sharp edges when compared to
traditional coating substrates.
