- Application Details
- ELASTOSIL® COLOR PASTE PT GREY RAL 7040 has been developed particularly for coloring ELASTOSIL® R and ELASTOSIL® R plus high consistency silicone rubber.
- ELASTOSIL® COLOR PASTE PT GREY RAL 7040 may be used for coloring silicone parts intended for sensitive applications and complying with the “Recommendation XV. Silicones" and “IX.
- Pigments for coloring plastics" of the BfR and FDA Regulation CFR 21 § 177.2600 "Rubber Articles Intended for Repeated Use" under observance of any given limitations on extractable and volatile substances.
- A statement regarding biocompatibility according to USP class VI and selected tests of ISO 10993 is available on request.
Processing
- 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.
