Effect-basecoat and its use for the coating process of polypropylene substrates.

摘要

2.1 It is intended to provide an effect-basecoat which produces a good flop effect on plastic substrates containing polypropylene. 2.2 The effect-basecoat comprises 5-35% by weight of physically drying binders, 0.5-15% by weight of chlorinated polyolefins having a chlorine content of 10-45% by weight and a molecular weight of 7000 to 130000, 0.5-15% by weight of cellulose acetobutyrate, 0.1-15% by weight of effect pigment, 0-20% by weight of coloured pigment and 50-87% by weight of solvent. 2.3 Preparation of effect-coatings on polypropylene substrates.
