Pigments for FRP

Organic pigments for frp sourced from India with grade selection, documents, and export support.

Fibre-reinforced plastics are pigmented mainly through pigment pastes dispersed in unsaturated polyester or epoxy resin, and gel-coats on exterior FRP face severe weathering. Organic pigments provide bright, durable colour for boats, tanks, panels and sanitaryware, but they must not interfere with the peroxide cure or catalyst system. Buyers sourcing from India should confirm the pigment is supplied or dispersible as a stable paste, does not inhibit or accelerate resin cure, and offers weather fastness suited to exterior gel-coats. Compatibility with the resin and consistent colour across large mouldings are essential for FRP quality.

What Pigments for FRP covers

Cure-system neutrality

FRP resins cure with peroxide catalyst and accelerator, so confirm the pigment neither inhibits nor accelerates gel and cure, which would weaken the laminate.

Gel-coat weather fastness

Exterior gel-coats on boats and panels face intense sun, so choose high-weathering organics that resist fading, chalking and colour loss over long service.

Stable pigment paste

FRP is coloured with pigment pastes in resin carrier, so require a stable, well-dispersed paste that mixes uniformly without settling or shade drift.

Uniform large-part colour

Large mouldings and hand lay-up need consistent colour, so verify tinting strength and dispersion give even shade across the whole part surface.

Answers

Pigments for FRP — frequently asked questions

How can a pigment affect FRP resin cure?

Some pigments or their carriers interact with the peroxide-accelerator system, either inhibiting cure so the laminate stays tacky or accelerating gel so working time is lost. Choose pigment pastes specifically formulated for polyester or epoxy FRP, and always run a cure trial checking gel time, hardness and full through-cure.

Why are gel-coats so demanding on pigment weathering?

The gel-coat is the exposed outer layer of an FRP part and takes the full brunt of UV, rain and salt for years, often on boats and outdoor panels. Pigments must resist fading and chalking there, so high-performance weather-fast organics are specified and backed by exposure data for the service environment.

Should I buy pigment as powder or paste for FRP?

Most FRP colouring uses pigment dispersed as a paste in a compatible resin carrier, which mixes easily into the polyester or epoxy without dispersion equipment. A ready paste gives uniform colour and avoids agglomerates. Confirm the carrier is compatible with your resin and that the paste stays stable in storage.

How do I keep colour consistent across large FRP mouldings?

Use pigment with consistent tinting strength and a well-dispersed paste, and control the addition ratio carefully during resin mixing. For hand lay-up and large parts, thorough blending prevents streaks. Batch-to-batch pigment consistency from your supplier is essential so repeat mouldings match the approved colour standard.
