ELASTOSIL® Color Paste FL Grey RAL 7040

1 of 230 products in this brand
ELASTOSIL® Color Paste FL Grey RAL 7040 is a ready-to-use masterbatch that contains specific pigments and reactive silicone polymers. It is commonly used for producing ELASTOSIL® liquid silicone rubber. This color paste enables homogeneous covulcanization without significantly affecting the physical properties, such as hardness, and without the risk of migration often seen in systems based on silicone oil.

Application Details
  • ELASTOSIL® COLOR PASTE FL GREY RAL 7040 has been developed particularly for coloring addition-curing ELASTOSIL® LR liquid silicone rubber and ELASTOSIL® RT RTV-2 silicone rubber.
  • ELASTOSIL® COLOR PASTE FL 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 under observance of any given limitations on extractable and volatile substances.
  • For sensitive applications requiring broader approvals, ELASTOSIL® COLOR PASTE FL WINDOW GREY RAL 7040 K1 may be an appropriate alternative.

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.
