ELASTOSIL® COLOR PASTE PT GRAY RAL 7040
ELASTOSIL® COLOR PASTE PT GRAY RAL 7040 is a ready-to-use compound comprising specific color pigments and a reactive silicone polymer which is commonly used in ELASTOSIL® high-consistency silicone rubber.
This ensures a homogeneous covulcanization of the color paste without interference of the physical properties (e.g. hardness) and without migration as observed with silicone oil.
Eigenschaften
ELASTOSIL® COLOR PASTE PT GRAY RAL 7040 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 a desired custom color tone.
ELASTOSIL® COLOR PASTE PT GRAY RAL 7040 is generally resistant to sunlight, UV and hot air. For further requirements the resistance should be checked in each individual case.
If the dosage recommendations are followed, the mechanical properties of the colored vulcanizates will not be impaired.

Datenblätter
ELASTOSIL® COLOR PASTE PT GRAY RAL 7040 has been developed particularly for coloring ELASTOSIL® R and ELASTOSIL® R plus high consistency silicone rubber.
ELASTOSIL® COLOR PASTE PT GRAY 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. Please see the actual Product Compliance Sheet of this product and/or the separate Food Contact Statement for detailed information about food contact including information about any limitation in view of dosage and/or condition of use that may apply for this product.
A statement regarding biocompatibility according to USP<88> class VI and selected tests of ISO 10993 is available on request.
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.
