ELASTOSIL® A 4

ELASTOSIL® A 4 is a carbon dioxide vulcanizing, solventless, one component, curable elastomer designed for silk screen applications. ELASTOSIL® A 4 is a moisture curing material with a very long skin-over time. Once ELASTOSIL® A 4 is in place on the substrate, the cure may be induced by exposure to a combination of carbon dioxide and moisture. Adhesion may be improved by mildly preheating the substrate.


Properties

  • Carbon dioxide cure acceleration
  • Designed for silk screen applications (typical bead height 2-5 mils)
  • Heat and oil resistant
  • Adhesion to many substrates

For specific processing information refer to, "Information Regarding Carbon Dioxide Accelerated Cures".

 

Storage

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.
