• ELASTOSIL® COLOR PASTE PT GREY RAL 7040 is compatible with Curing Agents C1, and C6 for peroxide curing ELASTOSIL® R grades and is also fully compatible with addition curing ELASTOSIL® R plus grades.
• For crosslinker E, the compatibility has to be tested in the individual case. Incorporation into ELASTOSIL® R and ELASTOSIL® R plus grades is best performed on an open roll mill.
• Preferably, the curing agent is incorporated at the same time. The color paste is homogeneously dispersed when the rubber stock has a uniform color. Customers may produce other colors by mixing the pigment pastes. Suggestions for formulations can be made on request.
• A dosage of 1% ELASTOSIL® Color Paste PT is generally recommended to obtain opaque vulcanisates. For the manufacture of thin-walled parts and for rubber grades containing non-reinforcing fillers (e.g. quartz, diatomaceous earth) or colored additives (e.g. ELASTOSIL® AUX Stabilizer R, ELASTOSIL® AUX Batch SB 2) an increase of the dosage to 2 - 3% will be useful.
• The concentration should be kept at a minimum. In individual cases an excess of color paste may slow down the curing characteristics.
