DEHESIVE® 908 is a solventless, addition-curing silicone fluid designed for release applications on both paper and filmic substrates. It is an essential component of a multicomponent release coating used in the manufacturing of paper and filmic release liners. These liners play a crucial role in the production of single- and double-sided industrial laminates.

Application Details

DEHESIVE® 908 is part of a multicomponent release coating to produce paper and filmic release liners. The liners are used for production of single and double-sided industrial laminates.

Mixing Order

  1. First pour in CRA® modifier in case CRA® is used.
  2. Add DEHESIVE® 908 in several portions and stir slowly until the mixture is homogeneous.
  3. Thoroughly stir in crosslinker until the mixture is homogeneous.
  4. 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. To avoid pressure formation store in ventilated containers.

Coating

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