Application of laboratory coater on release paper with glue [video demonstration]

NBCHAO laboratory coating machine is a classic application of scraping glue on release paper. In this issue, imported RDS wire rods are used for scraping, which cooperates with the vacuum adsorption function of the coating machine.

One of the more popular applications of laboratory automatic coating machines is to scrape glue, polymer materials, etc. on release paper. Release paper is a special type of paper whose surface is usually coated with a non-adhesive material, such as silicone oil or coating, to allow it to act as an isolation during the bonding process. In this way, the release paper prevents the adhesive from sticking to the surface of the paper, making it easy to peel off or detach the adhesive when needed without damaging the paper or adhesive. It has good temperature resistance and chemical resistance. From the perspective of physical properties, release paper is a soft substrate, and the coating film should be equipped with vacuum adsorption function to keep the substrate flat, otherwise it will affect the coating effect.

The glue applied to the release paper is mainly used to provide temporary adhesion or fixability for the object during the bonding or packaging process, so that it can be easily peeled off or detached when necessary. Including lamination packaging, mold making, printing advertisements, handicrafts, etc., it is widely used. The glue in this experiment has low viscosity and good leveling, so an imported RDS mayer-rod is used for scraping to ensure higher film accuracy.

Let's take a look at the specific experimental process.

Judging from the final experimental effect, the uniformity of the coating film is very OK. For the application of coating film on film and release paper substrates, the North-South Tide Coating Machine is still a relatively mature application, and the scraping effect is as always.
