When adding a liquid pigment to a resin system we suggest you use no more than 5% of the total amount of resin, as a higher percentage may prevent the resin from curing properly. These dyes may be used to achieve a highly transparent finish (optically clear), or when a higher percentage is added it may achieve a more translucent finish (still maintains clarity but no longer optically clear). A great example of this is when pigment is added to a coating epoxy vs a casting epoxy. When the resin is poured at only a few mm thick, the colour may appear less intense or vibrant compared to a casting application that may be anywhere from 5mm-100mm deep. The PSTF dyes work very well in conjunction with powder pigments such as the Pearl-Ex range of mica powders, and the PolyColor powder pigments. A great example of this is when a project requires a powder pigment, but as these do not disperse and dissolve into the resin, you may use a dye to create a base tone rather than leaving it clear. This can create dimension within the resin pour or re-enforce the powder pigments tone. For example, PSTF in Turquoise mixed with Pearl-Ex Turquoise creates a rich turquoise finish. A colourless powder pigment such as the Diamond Dust PolyColor powder may be used with any PSTF to create a metallic finish in the tone of your choice.
