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.
