SP131 is a foaming, moisture curing, one-component polyurethane adhesive for bonding sandwich panels and similar constructions of various materials. In the process of curing, it will foam and expand to make the uneven surface level.
Key Features:
- Solvent free.
- Room temperature curing
- High expansivity, high strength and good filling and leveling to bonded substrate;
- Easy to use, pumpable, and less consumption.
Typical Applications:
It is used primarily for bonding sandwich panels with skin materials of pre-treated or primed aluminum, steel, glass fiber reinforced plastic and core materials of plywood, wood, extruded / expanded polystyrene and mineral wool.
This product is suitable for experienced professional users only. Tests with actual substrates and conditions have to be performed, ensuring adhesion and material compatibility.
