Processing
The substrate areas that will be in contact with the sealant must be clean, dry and free of all loose material such as dust, dirt, rust, oil and other contaminants. Non-porous substrates should be cleaned with a solvent and clean, lint-free, cotton cloth. Remove residual solvent before it evaporates with a fresh clean, dry cloth. For application from cartridges cut thread open, fix nozzle on top and cut to required bead size. The sealant can be applied in beads or layers. It requires moisture in order to cure.
It is the responsibility of the user to test the compatibility of the sealant with the adjoining materials. Incompatible substances like coatings or organic plasticizers can lead to discoloration of the sealant. Cleaning agents and gaseous emissions can damage the sealant in its function or change its appearance.
Due to the wide variety of possible materials and substrates, especially with plastics, WACKER cannot make any general statements regarding compatibility or adhesion. In case of doubt, users must carry out their own preliminary tests.
A decrease in temperature or humidity, as well as restricted air circulation, can significantly extend the time required for complete curing.
