Application Details

WACKER® CROSSLINKER V 88 is used for curing crosslinking solvent-based and solvent-free DEHESIVE® -systems. Batches of coating compound must be prepared in the order given below.

  1. First pour in CRA® Modifier in case CRA® is used.
  2. Add DEHESIVE® polymer in several portions and stir slowly until the mixture is homogeneous.
  3. Thoroughly stir in WACKER® CROSSLINKER V 88 to this mixture.
  4. Slowly stir in catalyst. Local over-concentrations needs to be avoided. Any contact to alkaline systems needs to be avoided.
