SEMICOSIL® 936 UV

SEMICOSIL® 936 UV is an RTV-1 amine cure system that cures on contact with moisture in the air and/or through exposure to high energy ultraviolet light.


Eigenschaften

  • Rapid UV acceleration
  • Shadow cure





Because SEMICOSIL® 936 UV begins to cure on contact with atmospheric moisture, all containers should be tightly closed in lightproof containers when not in use. Dip tanks should be no more than half full and blanketed with a dry, inert gas such as nitrogen. If a skin should form over the surface it may be removed by careful skimming. Spray equipment and brushes should be washed and wiped clean with organic solvents such as naphtha or mineral spirits after use.

A 5 second exposure with a D bulb at an intensity of 0.7 W/cm2 cures a 2 mil coating in less than one minute. A shorter exposure time can be achieved with achieved with higher intensities. The actual time for a given application should be determined on an individual basis. The adhesion of SEMICOSIL® 936 UV to most substrates can be enhanced by a 30 second to one minute preheat cycle at 60-70 °C before exposure to the UV source.

Lagerung

The "Best use before end date" of each batch is shown on the Certificate of Analysis. Storage beyond the date specified on the Certificate of Analysis 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.
