Kleiberit 707.9 is a reactive hotmelt adhesive for high strength bonds on edging. These cartridges are for use with Holz-Her edge banding machines.
Kleiberit 707.9 PU Hot Melt Cartridges provide high quality edge bonding on solid wood, HPL, PVC, veneer and duroplastic edges. This adhesive has high heat and cold resistance.
The substrates should be freshly cut at right angles and should be free from dust. Boards and edge material have to be acclimatized to room temperature. Maintain room temperature of at least 18°C, avoid draughts.
Roller application 120-160°C Reduce the temperature to approx. 100°C during work breaks. Particular attention should be paid to the accuratetemperature control when bonding HPL and solid wood edges. Work at the upper temperatures when bond and thick substrates. Low temperature reduces the wetting of the edges. Coat weight and pressures should be adjusted so that the applied adhesive pearls are slightly pressed out at the edges. Effective pressing out can be checked with a transparent test edge.
Chemical cross linking of PUR hotmelts requires moisture. Therefore sufficient air humidity has to be present during processing.
The green strength ensures that the product is durable and has a close joint and allows for further processing, such a flush milling of the edges. Thecross linking of the product, depending on the humidity will occur in 1-2 days. The final strength is reached after 7 days.
