Due to the different properties of aluminum surfaces, it is recommended to carry outtrial lamination Since PU melts are prone to polymerization in contact with moisture, storage and processing should be carried out in dry conditions. For this reason, the product is delivered in sealed containers.

ClearingFlushing the glue-bearing system before changing the glue, as well as regular flushing with TECHNOMELT PUR CLEANER 4 reduces the risk of accumulation of hardened residues of reacted glue. The glue-bearing, as well as rotating parts of the equipment on which the melt glue comes into contact with air should be thoroughly washed at the end of each production cycle or when glue growths or signs of polymerization appear. The solidified residues of PUR-melts can be removed only after their softening by the action of a suitable solvent, such as N-ethyl pyrrolidone (NEP) by mechanical means using non-abrasive scrapers. It is necessary to follow the instructions of the equipment manufacturer.

Safety precautionsThe product contains diphenylmethanediisocyanate. Even whenworking within the recommended temperatures, diisocyanate forms vapors. Ifthe recommended operating temperatures are significantly exceeded, the product may decompose into hazardous componentsdirectly in the glue-bearing unit. Thereforeit is necessary to take measures to remove the generatedvapors, for example, by using aspirationequipment. If the melt glue gets onthe skin, do not try to remove it. Consult a doctor.Read the safety data sheet.
