Experimental Automatic Film Applicator Application of UV Adhesive on Release Paper [Video Demonstration]

This issue is the application experiment of the laboratory automatic coating machine applying UV glue on the release paper. This is a typical application case of the coating machine. Judging from the final coating effect, it is quite good.

Coating UV glue on release paper by Film Applicators is a common application and is often used to make UV-curable tapes, adhesives, and other bonding materials. This process involves applying UV-curable glue to the surface of the release paper and then bonding another substrate to the adhesive-coated release paper. This application has many advantages such as fast curing, high-strength bonding, and bonding without the use of solvents.

The coating machine uniformly applies the UV-curable glue to the release paper by means of a coating roller, scraper or wire rod. The adjustability and control of the coating machine ensures that the glue is evenly distributed for a consistent fit in subsequent steps.

In actual production, another substrate, usually paper, film or other material, is bonded to the glued release paper after the coating is completed. This step forms an adhesive structure. The UV-curable glue solidifies quickly through UV irradiation, and the bonded substrate becomes very strong in a short time. UV-curable glue solidifies quickly under UV irradiation, so the coated glue becomes solid almost immediately. This feature can greatly improve production efficiency, reduce processing time, and avoid the problem of waiting for curing for a long time.

In addition, UV-curable adhesives do not release volatile organic compounds (VOCs) during the curing process, so they have less impact on the environment. This makes this application widely used in fields with high environmental protection and hygiene requirements.

In this experiment, UV glue is mainly applied to the release paper, then cured by rapid UV, and finally tested whether the thickness of the scraped glue layer meets the expected range. Let's take a look at the detailed experimental process of NBCHAO technology.

There are several points to note in this experiment: 1. The fluidity of the glue is relatively high, so the corresponding scraping speed should be fast; 2. The experiment adopts manual UV curing, and NBCHAO also supports the integrated function of customized UV curing, which is more convenient and fast.
