Application Details

WACKER® CROSSLINKER V 90 is used for curing addition crosslinking solvent-based and solvent-free DEHESIVE® -systems.

Processing

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 90 to this mixture.
  4. Slowly stir in catalyst. Local over-concentrations of Platinum needs to be avoided. Any contact to alkaline systems needs to be avoided.

Safety & Health

Safety Notes

Siloxane Crosslinkers should never get into direct contact with concentrated Platinum Catalysts or Alkaline Systems, since this may cause a spontaneous, uncontrolled emission of hydrogen. The formation of hydrogen might lead together with air to explosive mixtures.
