Clear or whitebase paint

Full mixing systemFull mixing systems are based on Resin Minimal Pigment Concentrates (20-30%) suitable to produce complete paints by

mixing with clear resins giving a full range of shades including deep tones

but are also suitable as tinting concentrates

Color or whitebase paint

Tinting system

Tinting pastes are those pigment concentrates used at a maximum

of 10% addition to adjust the shade of an already complete

Opacity / transparency / tint strength

During grinding the pigment undergoes significant changes in hue, tint strength and transparency. Not getting the maximum tint strength or transparency can be very costly.

Color cost pigment grinding RMPC vs. traditional

Economics Tinting system based on RMPC

Efficiency in pigment grinding

Paint manufacturers sometime sacrifice the extra strength to avoid running longer grinding cycles or using better production methods.
