Application Details

DEHESIVE® 811 may be used for coating of PE-laminated paper, polyester films (PET) and papers.

Processing

Generally DEHESIVE® 811 is diluted to give a formulation with an active substance content of about 5 %. However, depending on the substrate and coater system, DEHESIVE® 811 may be used with lower or higher active substance contents. Batches of coating compound must be prepared in the order given below.

  1. First pour in DEHESIVE® 811
  2. Add solvent and stir slowly until the mixture is homogeneous
  3. Thoroughly stir in Crosslinker V 24 to this mixture
  4. Thoroughly stir Crosslinker V 84 to this mixture
  5. Slowly stir in catalyst C 80

Suitable solvents are aliphatic and aromatic hydrocarbons (e.g. toluene, white spirit), esters and ketones. The cure speed depends on the formulation, type of substrate, quality of solvent, the chosen temperature and the effectiveness of the oven. Laboratory trials are recommended prior to using the material in production in order to verify that the vulcanization performance suits the intended application.
