Processing

1
Prepare the surface
Adhesive and sealing surfaces must be clean, grease-free and dry.
2
Application
Apply an even layer of bead and apply within the skin formation time.
3
Smoothing
Smooth the joint if necessary.
4
Curing
Cross-linked at room temperature by humidity; final properties after complete curing.

Important Notes

  • The currently valid Elkem data sheet (TDS and SDS) is authoritative, which we will be happy to send you.
  • Cross-linked by humidity; reseal opened containers tightly.
