The common problems and solutions in application are what everyone needs to pay attention to. Below, we will provide a detailed explanation for everyone.

1. Why does the release film material tend to curl up on both sides after being used for a period of time

After using the release film for a period of time, it performs well in the middle, but the wings at both ends rise. The main reason for this phenomenon is that the release film has a high degree of stretching during the bonding process with the protected product. After bonding, unnecessary retraction occurs when encountering high temperature environments. This problem often occurs in products from customers in the south. Therefore, attention should be paid to the impact of environmental temperature differences on product use during the production process, Avoid unnecessary surface stretching during the pasting process.

2. Why does the release film material experience delamination

When we remove the release film from our product, there is a large amount of residual adhesive left on the product, which is called release film detachment. This is a very troublesome task that requires professional personnel to clean it well. The wholesaler stated that there are multiple possibilities for this issue, with the most likely being that the pressure adhesive used for the release film product does not meet the regulations, which is too sticky, resulting in the release film product being peeled off with an external tension greater than the internal resistance and remaining on the product.

There is also a situation where there are chemical residues on the surface of the pre coated product during use. For example, if the surface is cleaned with a chemical agent before the film is applied and the film is quickly applied before it evaporates completely, the residual chemical substances will react with the adhesive, which can easily cause the release film to detach.

3. Why does the release film material sometimes not stick firmly

The biggest possibility is that the viscosity of the sensitive adhesive used in the production of release film products is not enough. Another possibility is that the pressure of the molding machine used by the user during the pasting process is not enough, or the surface of the profile is not clean, with dust or paint, which affects the pasting effect of the sensitive adhesive! If this problem occurs, it is necessary to take targeted measures, replace the sensitive adhesive, increase the pressure on the film, or pay attention to the effective cleaning of the surface of the profile during the film application to avoid such problems.
