ELASTOSIL® COLOR PASTE PT RED RAL 3000 has been developed particularly for coloring ELASTOSIL® R and ELASTOSIL® R plus high consistency silicone rubber. ELASTOSIL® COLOR PASTE PT RED RAL 3000 is intended for use in technical applications. For sensitive applications, like parts in contact with food or for use in the medical and pharmaceutical sector, ELASTOSIL® COLOR PASTE PT RED RAL 3000 F may be an appropriate alternative.
Processing
- ELASTOSIL® COLOR PASTE PT RED RAL 3000 is compatible with Curing Agents C1, C6, and E for peroxide curing ELASTOSIL® R grades and is also fully compatible with addition curing ELASTOSIL® R plus grades.
- 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.

- Properties
ELASTOSIL® COLOR PASTE PT RED RAL 3000 is ready-to-use and can be easily incorporated on an open roll mill or kneader. ELASTOSIL® Color Pastes PT can be blended with each other to achieve the desired color shade. The colors have generally a good resistance to sunlight, UV and hot air. The resistance should be checked for individual cases, especially for long term applications. If the dosage recommendations are followed, the mechanical properties of the colored vulcanizates will not be significantly impaired.
