Same as the pelletized version, only the polymer carrier is replaced by a liquid carrier. This allows the plastics and pigments to be highly dispersed and optimizes the color and capabilities of the pigments and additives. Color Master employs the use of non-toxic liquid carriers that can be easily cleaned up with water and mild detergents such as Simple Green. The liquid color concentrates are packaged and intended for use in a closed system. It does require the purchase of a relatively low-cost dosing pump. Color Master services liquid colorants for a wide range of industries.
