EXPANDABLE SEAL
EXPANDABLE SEAL is a solvent free, one component, polyurethane adhesive, having a thixotropic structure makes it suitable for vertical application. Expandable seal cures through reaction with moisture from the substrate and forms a strong, durable, and water-resistant. It is slightly expandable and, therefore, offers complete sealing and provides thermal insulating properties
Manufacture of sandwich elements made of
- Wood
- Rigid foam (polyurethane, extruded or expanded polystyrene)
- Aluminium, steel
- Gypsum or cement board
- Plastic
SURFACE PREPARATION
The substrate must be cleaned or removed down to a solid and stable base material by using wire brush and air blower.
APPLICATION OF PU ADHESIVES
It is applied on one of the two surfaces and then the two elements are joined together. For some applications, it might be necessary to use a mechanical support until the adhesive develops its strength.
