Our resins can be mixed with dyes and pigments at varying concentrations. For functional purposes, as controlling cure depth, concentrations between 0.25 and 2% by weight have been used.
This is: 100g resin contain between 0.25 and 2 g dye or pigment.
Our new hiperdispersed pigments (Red, Yellow, Black) are much more concentrated and need less of it to work in a similar fashion as the previous pigments. Rarely will you need more than 0.8% from these to work the same as their older counterparts.
