	<span lang="EN-GB">New regulations for hazardous air pollutants drove operations to
compliant coatings. Powder coatings were the most popular choice. A screening
of intumescent powder coatings was carried out comprising binders like
thermoplastics as plasticised polyvinylchloride and polypropylene as well as
non-cross linked thermosets as polyurethanes. Intumescence was achieved by
addition of the intumescent ingredient bicyclopentaerythritol phosphate, by the intumescent
combination polyethylene glycol as binder with ammonium
polyphosphate and binders comprising intumescent phosphororganic polyesters.
The intumescent ingredients and components were characterized by
thermogravimetric analysis and described by chemical formulas together with
their balances of weights and heats of formation. The electrically loaded
powders were sprayed on grounded steel panels and subdued a fire test. The
time, until the coated panels reached 500</span><span lang="EN-US">¡æ</span><span lang="EN-GB">, was observed. The panels coated with the
plasticised polyvinylchloride plus bicyclopentaerythritol phosphate and those
protected by the polyurethane comprising polyethylene glycol and ammonium
polyphosphate delayed the period of time, until 500</span><span lang="EN-US">¡æ</span><span lang="EN-GB"> were reached, significantly and were equal in
efficiency with the reference, the commercial water borne intumescent varnish.</span><span lang="EN-US"><o:p></o:p></span>
