Very high quality West & Senior SIGNAL RED pigment for polyester resin.

Use this pigment to add vivid colour to any polyester or vinylester laminating resin, casting resin or gelcoat. Suitable for moulds, parts and castings.

All West & Senior pigment dispersions are made the very highest quality with pigments triple milled to reduce them to the finest particle size. Smaller particles means more vibrant colours from less pigment, improving the appearance of pigmented parts whilst minimising the performance reduction of the resin caused by pigmentation.

Typical Uses

Use to add solid colour to polyester laminating resin, polyester gelcoat (for parts and moulds) and polyester casting or potting resins. A pigment ratio of 5-10% should be sufficient to add solid opaque colour in most applications.

Advantages

Pigment dispersions (pastes) should always be used when pigmenting polyester resins and gelcoats rather than pigment powder because the rigorous milling and mixing process during manufacture ensures that the tiny pigment particles are fully dispersed into a small amount of carrier polyester, getting the very most from their colour.

When a dispersion is then added to the bulk of the polyester resin it blends in easily, ensuring that the pigment is thoroughly mixed through the resin (rather than staying in lumps).

Because the dispersion is actually a mix of resin and pigment already, it is essential that the correct dispersion type is used to pigment each specific resin type. For example, polyester resins and gelcoats should only ever be pigmented using polyester dispersion pigment.

Can’t find the answer you’re looking for?Ask our technical team a question.

The quantity of resin used in the pigment dispersions is very small and as such when the pigment is mixed into another resin, the additional amount of resin from the pigment is very small and in practical terms insignificant. As such you do not normally need to account for it within the mixing ratio calculations.

No, unfortunately you cannot use a pigment from one resin type with another resin type. You must use the correct pigment for the resin type you are using - eg a PU resin needs a PU pigment, a polyester resin needs a Polyester pigment and an epoxy resin needs an epoxy pigment.

This is because the pigment dispersions are a blend of pigment powders AND a small amount of base resin. Mixing the wrong pigment with a resin system may inhibit the resin cure and damage the end product

Yes, you can use the pigments in a resin infusion process, however if you are not using a gelcoat you will still get the colour from the fibre showing where it contacts the surface, with glass fabric the effect is diminished as the fibre is clear, but with densely coloured fibre like carbon it may affect the pigment.

If you need a very solid colour for epoxy infusion I would advise using Polyester Pigment in the GC50 Epoxy Compatible Gelcoat.

When using a pigment paste, it is best practice to mix the paste into the resin part of the mixture. We recommend doing this before adding the catalyst/hardener as it means you have as much time as you need to get a good even colour mixture without having to worry about reduced pot life.

The pigments used in this pigment dispersion will be excellent in terms of light fastness and weathering characteristics. If you are not already aware, pigments are graded for these properties on a blue wool scale, with 7-8 being the best. We tend to only source such grades for our dispersions with such high quality. However, the base resin system you are using these pigments with may be vulnerable to UV yellowing itself.

This pigment is part of West and Senior's FastCol colour range which is a range of basic colours without RAL numbers associated with them.

Our polyester pigments can also be used to pigment vinylester resins.
