ELASTOSIL® COLOR PASTE PT RED RAL 3000

ELASTOSIL® COLOR PASTE PT RED RAL 3000 is a ready-to-use masterbatch comprising specific pigments and reactive silicone polymers which are commonly used to produce ELASTOSIL® high-consistency silicone rubber.

This ensures a homogeneous covulcanization of the color paste without significant impairment of the physical properties (e.g. hardness) and without migration as it may be observed for systems based on silicone oil.



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.

Specific features of ELASTOSIL® COLOR PASTE PT RED RAL 3000

  • Additive

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. For further details please see TDS and PCS of ELASTOSIL® COLOR PASTE PT RED RAL 3000 F.

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.

Packaging

This product is available in 20 kg cardboard packaging and 1kg tin.

Storage

Please store the cardboard boxes in a dry and cool place. Already opened boxes should be closed again to avoid any contamination.
The 'Best use before end' date of each batch is shown on the product label.
