The pigment is added to PART A of the polyurethane at a ratio of 4% or lower depending on the density and vibrancy of the desired finish. Stir thoroughly into Part A and continue the mixing procedure as normal. Different coloured Pigments can be mixed to create custom colours. With non clear resins using very small amounts of black will turn the polyurethane grey and small amounts of red will turn it pink.
*Addition to silicone rubber is not recommended as it will have a thixotropic effect making it non pourable. Please view silicone pigments if you wish to colour silicone rubber.*
