Offline Low-E glass Protective Film

In a known technique for preventing surface damage (scratches, contamination, corrosion, etc.), protective sheets are bonded to surfaces for protection during the processing and transportation of various articles. The objects to be protected vary greatly. For example, protective sheets are also used on glass panels with low-E (Low radiation) layers.

Glass panels with Low-E layers are preferred for use as building materials such as window panes since the role of Low-E layers is to increase the efficiency of cooling and heating interior Spaces. In the manufacture of such glass plates, a protective sheet is usually attached to the surface of the Low-E layer by its adhesive layer until a glass plate having a Low-E layer and another glass plate are assembled into a pair of glass with the surface of the Low-E layer on the inside (for example, a double layer of glass), otherwise, the Low-E layer will be exposed. This protects the Low-E layer from damage, wear, deterioration, corrosion, etc.

PSA tablets used for surface protection are removed by adhesive at appropriate times after achieving the purpose of protection. Therefore, PSA is designed to have relatively low bonding strength. In particular, for adhesives with large surface areas, limiting adhesion strength is important to avoid slow de-molding (severe stripping) and maintain effective removal.

For example, considering the efficiency of manufacturing, transportation, etc., glass panels for building materials such as window glass, represented by glass panels with Low-E layers, are experiencing an increase in area, and the surface width of mainstream parts is now greater than 2.6m, or even more than 3m. An increase in the surface area of the adhesive can lead to an increase in the adhesive area of the protective sheet (PSA sheet) and further severe stripping. Thus, from the point of view of removal efficiency, the adhesion strength is expected to be limited to the minimum level required.

Changsheng is also a company dedicated to the research and development, production and sales of emulsion pressure-sensitive adhesives. We can effectively solve the problems that customers encounter in the use of glue because of different production equipment and technology.

We specialize in the production of protective film and pressure-sensitive adhesives for many years, with our own R & D team. In the future, through continuous research and development and summing up experience, our glue can be applied to more product application fields.
