- Vibration-resistant bonding
- Can be removed without residues from steel formwork
Applıcatıon descrıptıon
Adhesives used in the manufacturing of precast concrete parts are expected to provide a very good adhesion and a fast build-up of strength, while also facilitating a clean removal from the sheating elements after the concrete has dried.
The fast build-up of strength of the PO-based hot melts facilitates a fast manufacturing process in which the concrete can be poured into the forms a few minutes after bonding. In addition to that, the adhesives are resistant to vibrations and provide a flexible bondline with high strength values, which can compensate for the vibrations when the concrete is compacted with plate vibrators and keeps the formwork elements in place.
A key characteristic of the PO hot melt adhesives is their relatively easy removal from the formwork elements when cold. This means the formworks can be reused for the casting of concrete parts and facilitates a superior appearance of the bond. We can supply adhesive alternatives with different open times which are designed for lower and for higher ambient temperatures respectively.
