Improve cleaning efficiency with non-stick fluoropolymer coating!

You were troubled by the adhesion issues with the glue pot for the back gluing of the binding machine and the perfect binding machine. The glue used is a reactive hot melt adhesive that has a very strong bonding power even in small quantities, and it is a high-priced specialty product. Once it hardens while adhered, the peeling process becomes very difficult, and it cannot be reused, resulting in significant waste. Issues: 1. Since the glue has a strong bonding power, high non-stick properties are required. 2. As it is hot melt, the glue pot is constantly heated with a heater. 3. After removing the glue pot for processing, it must be immediately surface-treated and delivered for installation.

basic information

Initially, we proposed a non-stick coating that had the highest non-stick properties and had a proven track record in other hot melt application lines, and it was tested and adopted. The release properties at the time of delivery were as expected and good. However, within a few weeks, there was a significant deterioration in performance. It was assumed that this was due to localized heating from the heater being more concentrated than anticipated, exceeding the heat resistance temperature. *The heat resistance temperature of the non-stick coating is 150°C.* Therefore, we proposed a fluoropolymer coating that has heat resistance and excellent non-stick properties. There are various types and grades of fluoropolymer coatings, but this time we specifically selected a grade of PFA that excels in non-stick properties. Points: 1. The heat resistance temperature of PFA coating is 260°C, allowing for safe use at the heater's set temperature (200°C). 2. While non-stick properties are primarily required on the inner surface, we treated both the inner and outer surfaces to ensure coating adhesion and prevent the adhesion of scattered adhesive. 3. We also accommodate short delivery times.
