I believe that many manufacturers who need to convert to PUR equipment or are using PUR hot melt adhesive will want to know the usage temperature of PUR hot melt adhesive. Here we will share with you the temperature of PUR hot melt adhesive for edge banding, flatting and wrapping processes.
PUR hot melt adhesive usage temperature sharing:
PUR hot melt adhesive is currently used in woodworking and profile processes. It is mainly divided into three processes: edge banding, flatting and wrapping.
First let’s talk about the use temperature of PUR edge banding hot melt adhesive. we recommend that the use temperature of the glue tank is between : 150-160℃, platen temperature: 140-180℃ in winter; 120-160℃ in summer, hose temperature: 140-180℃ in winter; 120-160℃ in summer.
next is the usage temperature of PUR wrapping hot melt adhesive. we recommend platen temperature: 130 – 150 ℃ in winter; 115 – 135 ℃ in summer. Squeegee temperature: 115 – 135 ℃ in winter; 100 – 120 ℃ in summer.
The last is the PUR hot melt adhesive flat application process. Our recommended usage temperatures are: rubber roller temperature: 120±20℃, steel roller temperature: 160±20℃, and glue tank temperature: 120-140℃.
The above are the recommended temperatures for each component of the three processes of PUR hot melt adhesive. However, when using glue at the factory site, it needs to be slightly adjusted according to the on-site temperature.
The principle of using glue is “wetting first, temperature second” to ensure that the glue apply evenly to the substrate and increase the gluing temperature appropriately.
