Cambridge Blue Pearl pigments


The mouldcraft Luster Pearl pigments powder  range produce amazing vibrant colours and are ideal for use with our resins
They produce metallic effects to castings and topcoats perfect for the now very popular river table projects also jewellery, and other projects like pen blanks, resin art pictures and much more. mouldcraft Luster Pearl pigments are  safe, inert powder pigments and due to the differing particle size (10-60 microns) across the range of different colours the effect can vary from a smooth pearly lustre to a strong metallic effect. Mouldcraft Luster Pearl pigments do not contain any  metal so will not fade or tarnish over time. mouldcraft Luster Pearl pigments range all have differing densities and are sold by weight (not volume).

Resin Compatibility

mouldcraft Luster Pearl pigments are suitable for use with:
Epoxy resins such as our clr  range
Polyester resins such as our Waterclear Polyester Casting Resin

mouldcraft Luster Pearl pigments have been tested with products from our own range but should also work well with resins from other manufacturers, however you should always conduct your own tests as to their compatibility with other resin systems and test the effects before completing the project.

How to Use

When using resin systems with the mouldcraft Luster Pearl pigments range ‘less is more’. It is best practise to add a small amount and mix well then add more pigment if a more intense colour or metallic effect is required.

Remember that thicker castings will require a lower percentage of pigment because the colour will appear stronger the thicker the section is. Conversely, thinner castings will require a higher percentage of pigment in order to appear to be the same colour as thicker castings.

If you are you are using a resin with a short pot-life it is best to use a small amount of resin, mix in the mouldcraft Luster Pearl pigments until you reach the desired colour. Adding small amounts at a time and ensuring no lumps remain in the resin before combining the pigmented resin with the hardener - once the resin and hardener are combined the working time will begin. Alternatively if you are working with a longer pot-life resin use a small amount of combined resin and hardener to mix the powder pigment into. When you are happy no unmixed pigment remains add the rest of the combined resin.

When adding pigments to more reactive materials such as fast curing polyurethanes you will find it helpful to mix the pigment into one side of the resin (either part A or part B) thoroughly before mixing the two parts together and starting the reaction. This allows as much time as is needed to thoroughly disperse the pigment before starting the reaction. If you do choose to pigment just one side of the resin first it's helpful to remember that the addition of the second half of the resin will 'dilute' the tint when you add it.

Work in a well ventilated environment and avoid breathing dust.
