ELASTOSIL® Color Paste FL Polarblue

1 of 230 products in this brand
ELASTOSIL® Color Paste FL Polarblue is a ready-to-use masterbatch comprising specific pigments and reactive silicone polymers that are commonly used to produce ELASTOSIL® liquid 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 may be observed for systems based on silicone oil.

Application Details
  • ELASTOSIL® COLOR PASTE FL POLARBLUE has been developed particularly for coloring addition-curing ELASTOSIL® LR liquid silicone rubber and ELASTOSIL® RT RTV-2 silicone rubber.
  • It is a diluted version of ELASTOSIL® COLOR PASTE FL BLUE RAL 5022 intended particularly for the production of translucent parts. ELASTOSIL® COLOR PASTE FL POLARBLUE 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

Before using ELASTOSIL® COLOR PASTES FL, the paste must be thoroughly stirred. This is also required if there has been a long interruption in production. It may be necessary to repeat this procedure in case of very long production runs. Depending on the color intensity desired, 0.5 to 4.0 % pigment paste should be added, the usual dosage being 2 %. Generally, the dosage should be kept at a minimum. In individual cases, an excess of color paste may slow down the curing characteristics. Customers may produce other colors by mixing pigment pastes. Suggestions for formulations can be provided on request.

Properties

ELASTOSIL® COLOR PASTE FL POLARBLUE is pourable and ready-to-use after stirring up. A dilution is not required. 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.
