ELASTOSIL® Color Paste FL Yellow RAL 1026

1 of 230 products in this brand
ELASTOSIL® Color Paste FL Yellow RAL 1026 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 YELLOW RAL 1026 has been developed particularly for coloring addition-curing ELASTOSIL® LR liquid silicone rubber and ELASTOSIL® RT RTV-2 silicone rubber. ELASTOSIL® COLOR PASTE FL YELLOW RAL 1026 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 FL YELLOW RAL 1026 F 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.

Properties

ELASTOSIL® COLOR PASTE FL YELLOW RAL 1026 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.
