ELASTOSIL® COLOR PASTE FL UV FLUORESCENT
ELASTOSIL® COLOR PASTE FL UV FLUORESCENT is a ready-to-use masterbatch comprising a specific flurescent agent and reactive silicone polymers which are commonly used in ELASTOSIL® liquid silicone rubber.
This ensures a homogeneous covulcanization of the color paste without impairment of the physical properties (e.g. hardness).
ELASTOSIL® COLOR PASTE FL UV FLUORESCENT is pourable and ready-to-use after brief stirring before using. A dilution is not required.
If the dosage recommendations are followed, the mechanical properties of the colored vulcanizates will not be impaired.
Specific features of ELASTOSIL® COLOR PASTE FL UV FLUORESCENT
- Low volatile
ELASTOSIL® COLOR PASTE FL UV FLUORESCENT has been developed particularly for coloring addition-curing ELASTOSIL® LR liquid silicone rubber and ELASTOSIL® RT RTV-2 silicone rubber.
ELASTOSIL® COLOR PASTE FL UV FLUORESCENT has been developed specifically for fluorescent marking of addition-cure silicone rubber. Silicone molded parts or coatings pigmented with this color paste give off a deep blue-violet glow when irradiated with UV light. Silicone processors can exploit this property to develop automated quality control systems for their manufacturing setup.
Before using an ELASTOSIL® COLOR PASTE FL, the color paste must be thoroughly stirred. This is also necessary if there has been a long interruption in production or from time to time in case of very long productions runs.
Depending on the color intensity desired, 0.5 to 4.0 % pigment paste should be added. The concentration should be kept at a minimum. In individual cases, an excess of color paste may slow down the curing characteristics.
This product is available in 20 kg pail and 1kg tin.
The 'Best use before end' date of each batch is shown on the product label.
Storage beyond the date specified on the label does not necessarily mean that the product is no longer usable.
In this case however, the properties required for the intended use must be checked for quality assurance reasons.
