Application Details

DEHESIVE® 920 is part of a release coating system for paper and filmic substrates.

Processing:

DEHESIVE® 920 is used in combination with crosslinker and platinum catalyst and if applicable CRA® release modifier.

Mixing order

  • First pour in CRA® modifier in case CRA® is used.
  • Add DEHESIVE® 920 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. 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.
