POWDER COATING COMPOSITION FOR COATING SURFACES OF THERMOPLASTIC COMPOSITES

摘要

A powder coating composition for coating on thermoplastic composites comprising an intimate mixture comprising: A) 50 to 99 wt% of at least one ethylene vinyl acetate copolymer with a vinyl acetate content in the range of 10 to 30 wt%, B) 1 to 50 wt% of at least one thermoplastic and/or thermosetting binder resin, and C) 0 to 20 wt% of at least one pigment and/or filler, the wt% amounts are based on the total weight of the powder coating composition A) to C); the powder coating composition has excellent adhesion to thermoplastic composite as well as an enhanced impact resistance; and is suitable for use as a pigmented or unpigmented coating composition for thermoplastic substrates based on a composite of glass and thermoplastic fibers and provides a completely recyclable thermoplastic composite coated with the thermoplastic powder coating composition.
