DEHESIVE® 636 is a solvent-free, addition-curing silicone fluid designed for release applications, commonly applied with additional components, especially on filmic substrates. Its excellent curing properties make it suitable for use with temperature-sensitive substrates or low levels of platinum catalyst. DEHESIVE® 636 is an integral part of a multicomponent release coating used in the production of paper and filmic release liners and widely employed in the manufacturing of single- and double-sided industrial laminates.

Application Details

DEHESIVE® 636 is part of a multi-component release coating to produce paper and filmic release liners. The liners are used for production of single and double-sided industrial laminates.

Processing

Mixing order

  • First pour in CRA® modifier in case CRA® is used.
  • Add DEHESIVE® 636 in several portions and stir slowly until the mixture is homogeneous.
  • Thoroughly stir in crosslinker homogenously.
  • Slowly stir in catalyst homogenously and avoid local over concentrations.
  • Make sure that catalyst poisons are avoided in batch preparation and processing steps.
  • For a short time compounded batches may emit small amounts of hydrogen. Store in ventilated containers to avoid pressure formation.

Coating

Modern coating systems are particularly effective with DEHESIVE® systems. The batch is best added directly to the nip of the coating unit.
