PUR Adhesive Profile Wrapping Machine: The adhesive strength of PUR glue far exceeds that of ordinary hot melt adhesive

The PUR Adhesive Profile Wrapping Machine produced by our company can meet the wrapping requirements of various profiles. By using various pressure wheels to simulate the manual veneering action, decorative material films or wood veneers are attached to the surface of the base material. 

 

PUR Adhesive Profile Wrapping Machine

The full name of PUR is Polyurethane Reactive,Like hot melt adhesives, PUR melts into a liquid when heated. When cooled, it solidifies rapidly, providing extremely strong adhesive force.The melted PUR adhesive will undergo an irreversible chemical reaction with moisture in the air. This reaction will make the PUR glue very hard.The main advantage of the glue in the PUR Adhesive Profile Wrapping Machine is its high-temperature resistance. Ordinary EVA glue may melt at 60-70°C, while PUR glue can withstand temperatures above 120°C for a long time, making it highly suitable for use in high-temperature environments.

The PUR glue also has extremely strong water resistance and adhesion. It is highly suitable for applications in humid environments. However, the price of PUR glue is much higher than that of ordinary hot melt glue.The biggest drawback of PUR glue is that it is very difficult to clean. Once fully cured, it will be extremely difficult to remove.

The daily maintenance of the PUR Adhesive Profile Wrapping Machine is also very important. Check whether the sealing ring of the glue bucket installation seat is intact and ensure that the glue bucket is absolutely sealed at the connection with the rubber hose to prevent moisture from entering. At the end of each day's work, all the melted PUR glue in the glue gun and the glue delivery hose needs to be completely drained. Prevent residual PUR glue from curing inside the pipes and glue guns.
