ABSTRACT:
The invention provides a powder coating composition prepared from a combination, the combination comprising:A) at least one binder resin and, optionally at least one curing agent,B) at least one calibrated pigmented liquid, based on at least one pigment, and,C) optionally, at least one pigment and/or extenders and/or additive.The powder coating composition of the invention provides a precise color of the coatings having a desired color with high color stability. Therefore there is no need for additional adjustment tests or re-working procedures, and, therefore, it makes it possible to offer efficient, small-batch manufacture of custom colors, for example, to match a swatch of fabric supplied by a customer.
