• ready gunnability at low (+ 5 °C) and high (+ 40 °C) temperatures
• flexible at low (- 40 °C) and high temperatures (+ 100 °C)

Application details-Application fields

• Sealing applications (car, boat, caravan, house)
• suitable for many general industrial sealing and bonding uses

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 a clean, lint-free cotton cloth. Remove residual solvent before it evaporates with a fresh, clean, dry cloth.

For application from cartridges, cut the thread open, fix the nozzle on top and cut to the required bead size. The sealant can be applied in beads or layers. It requires moisture to cure. The curing time can take longer at lower temperatures, lower humidity or with a low volume of air exchange.
