What are the reasons for the decrease in the viscosity of PVC edge banding
PVC edge banding has a good protective effect on the product, so it will be used in the decoration of many items, and most of them are fixed with adhesives, so if degumming occurs, it will have a great impact on the product. So, what are the reasons for the decrease in the viscosity of PVC edge banding adhesive?
There are many reasons for the degumming of the edge banding. One is its own quality problem. One of the processing and production standards for high-quality edge banding is good adhesive performance. For example, the adhesive coating on some inferior edge banding strips is too thin, and the effect is naturally not good when applying glue. The second is the temperature of the bonding environment. In addition, the surface of the board is not flat, sealed, or the glue is too thin. It will also affect the normal gluing of the edge banding. In addition, the temperature of the edge banding machine is insufficient, and the hot melt adhesive used loses the stable condition of hot melt adhesive bonding in a low-temperature environment. There are many reasons for the degumming of PVC edge banding, and we need to adopt different solutions according to different reasons.
The above is the reason why the viscosity of PVC edge banding tape has decreased. I hope it will help you.
