<p>A powdered coating material containing (wt.%): <??>(A) at least one multifunctional solid epoxide resin thermally crosslinkable via the epoxide groups; <??>(B) at least one solid, linear epoxide resin based on bisphenol A, AD and/or F, of maximum functionality 2 with respect to thermal crosslinking via the epoxide groups; <??>(C) an inorganic filler; and <??>(D) at least one curing agent is new. <??>A powdered coating material containing (wt.%): <??>(A) at least one multifunctional solid epoxide resin (40-65) thermally crosslinkable via the epoxide groups, of epoxy equivalent 380-420 g/equ, an ICI-melt viscosity at 50 degrees C of 2800-5000 mPas and softening point 95-105 degrees C; <??>(B) at least one solid, linear epoxide resin based on bisphenol A, AD and/or F (20-30), of maximum functionality 2 with respect to thermal crosslinking via the epoxide groups; <??>(C) an inorganic filler (15-30); and <??>(D) at least one curing agent (1-10) is new. <??>An Independent claim is also included for a functional long lasting coating for use at high operating temperatures from substrates obtainable from the above powdered coating material by thermal crosslinking.</p> |
