Designed as a colouring medium for polyester compression moulding, polyester extrusion and

injection moulding, polyester flat sheeting production, polyester casting, and general

composite construction involving styrenated polyester resins.

Colorwell are coloured liquid/paste mediums based on

pigments dispersed within a solvent-free reactive unsaturated polyester resin. They are

available in a wide range of colours varying in strength and consistency depending upon the

particular colouring application. They have been developed to blend easily into resin

systems. The range of colours is based upon pigments carefully selected for colour fastness,

opacity, heat stability and having minimum effect upon the curing characteristics of the final

system. The resin used with the Polyester Colour Paste is a specially developed solvent-free

reactive polyester resin which chemically cross links with the moulding resin so that the colour

is "locked in" once the system has cured. They can be used to colour most polyester resinbased

systems used within the composites or related industry. Our Polyester Colour Pastes

have excellent stability.
