For flexible bonding of temperature insensitive materials. Good adhesion to plastics, such as PE, PP, PS và PC, as well as to lớn wood, & steel. Ideal assembly hot melt adhesive with a wide range of applications, also on non-absorbent surfaces. Flexible bondline which can absorb vibrations.The hot melt is adapted for use in the production of precast concrete parts due khổng lồ its special characteristics, e.g. For positioning polystyrene or wood mouldings, electrical components, or spacers. This application not only requires a good adhesion of the adhesive lớn the substrates. A reliable bond also has to lớn ensure resistance against the vibrations occurring when the concrete in the formwork is compacted with plate compactors. In addition, these thermoplastic adhesives leave no residues when removed after cooling from the formwork panels. This is especially important for a superior appearance of precast béton brut parts, and also allows khổng lồ reuse the formwork panels as well as other relevant parts used in the manufacture of precast concrete.

The PO adhesives are usually supplied in block, granulate or pillow form and are heated in standard melting units to lớn a temperature of approx. 180 – 200 °C và applied onto one substrate as beads using a hot melt gun or sprayed onto the full surface. The cartridges are usually used in hand hot melt guns. Lớn ensure an optimum adhesion, the surface to be bonded has lớn be clean, dry and không lấy phí of oil.To achieve a sufficient bond strength, the part with the adhesive only has khổng lồ be pressed firmly onto the formwork panel for a few seconds. On cooling, the adhesive will build up its cohesive strength as well as the adhesion between the bonded parts. The wide range of adhesion of the adhesives facilitates a reliable bonding of many, different materials. The specified mở cửa time indicates the maximum processing time of the hot adhesive, directly after application onto the substrate until fastening, e.g. On a formwork panel.When the adhesives are heated again, they become soft and liquid & facilitate a repositioning of the bonded parts without any significant loss of adhesion.The adhesive application amount should always be high enough to lớn ensure a sufficient adhesive coating, i.e. The surface to lớn be bonded should be fully wetted.
