Brief Introduction Polyester Pigments Shades

Colourtech Polyester Pigments are used for coloring Fiberglass Reinforced Plastics (FRP). These pigments are superior quality, stable pigment concentrates formulated with a high loading of dry organic/inorganic pigment powders in an unsaturated/ non- styrenated polyester resin. The pigment dispersions are free from plasticizers. The base resin is manufactured in-house. This carrier resin combines chemically with the moulding grade of commercial resins during curing. They exhibit high gloss, have good dispersion properties and also give excellent coverage in the moulded product.


Colourtech Pigments are compatible with almost all the commercial grades of resins available in the market today. They are offered for different fabrication methods such as Hand Lay-Up, Spray Lay-Up, SMC, DMC, Pultrusion, Filament Winding, Vacuum Bagging, RTM, and RFI. Currently our pigments are supplied to a wide range of critical applications and industries, including construction, automotive, marine, aerospace, electronics, petrochemical, industrial and recreational/consumer industries.

Specialized electrical grades, corrosion resistant grades, marine grades are also manufactured. They are offered in various colours and display a high degree of grinding, dispersion.

Usage Levels

The following is a recommended usage level of Colourtech Polyester Pigment with commercial grades of resins. The percentage loading listed below is to be calculated on the weight of the molding resin

8-12 % For Gel Coats
4-6% For Laminates
8-10% For SMC/DMC Mouldings
1-4% For Translucent Sheets
4-6% For Filled Castings
8-10% For Pultrusions

Insufficient pigments may lead to non- uniformity of colour and other surface defects. Higher pigmentation levels will provide better colour uniformity, color depth,  brightness and longer durability
