Application method of liquid color pigment:
First, decide how much colour paste to add—either by eye against the raw silicone or by using a Pantone number. If your injection moulder has a paste pump, simply dial in the ratio through the controls. If not, you’ll need to stir the paste thoroughly into the B component, then mix that with A, pull a vacuum to remove air, and shoot it into the tool. Heat the mould to 115–135 °C (check your silicone’s data sheet) and hold for 200–300 seconds, but lengthen or shorten this based on how thick or complex your part is.
