<p>A powder coating material comprising, based on the coating material, (A) from 40 to 65% by weight of at least one solid epoxy resin which is polyfunctional in respect of thermal crosslinking by way of the epoxide groups and has an epoxide equivalent weight of from 380 to 420 g/equ., an ICI melt viscosity at 150.degree.C of from 2800 to 5000 mPas, and a softening point of from 95 to 105.degree.C, (B) from 15 to 35% by weight of at least one solid, linear epoxy resin based on bisphenol A, AD and/or F, having a functionality in respect of thermal crosslinking by way of the epoxide groups of not more than 2, (C) from 15 to 30% by weight of an inorganic filler and (D) from 1 to 10% by weight of at least one hardener; and its use for producing functional coatings for substrates for high long-term service temperatures.</p> |
