Preparation of Polymer Film by PET Substrate Applied by Experimental Coating Machine

This article mainly shares the coating case of the polymer film prepared on the pet substrate, and configures a suitable coating solution according to the experimental requirements.

When choosing the film coating machine directly, Beichao Technology will first understand the specific details of the user's coating film. First of all, what is the substrate of the coating film, and the functions of different substrate configurations are different. PET is a kind of film, obviously The characteristic is that if the substrate is scraped by hand, it is difficult to keep it flat and easy to wrinkle, so it needs to be equipped with vacuum adsorption to maintain its flatness.

Second, what is the sample of the coating film? What is the thickness of the coating film? Polymer glue, the film thickness is about 100 μm, the viscosity is not big. First of all, as glue, the viscosity is very important. For wire rods, it is not suitable for scraping samples with a viscosity above 1000cp, and scratches are easy to appear. At this time, a wet film preparer or a knife coater is required. In addition, the film thickness is relatively thin, such as less than 10 microns, which is relatively thin, so the precision requirements of the optional Applicator must be relatively high. If it is about 100 microns, then the general scraper Applicator can be satisfied.

Finally, whether the sample needs to be heated and dried is to determine whether to configure the heating function, etc.

Based on the above analysis, the coating solution recommended by Beichao Technology is a four-in-one automatic film coating machine or a two-in-one (wire rod adsorption function), and the choice is made according to the actual budget. The details are as follows:
