One, the differences between cold glue wallpaper and hot glue wallpaper
1、What are hot melt adhesive and cold melt adhesive?
"Cold glue" actually refers to liquid-type adhesive. Typically, it comes in a bottle, and once the bottle is opened, it can be used immediately. "Hot glue," on the other hand, is a type of hot-melt adhesive, which can be in the form of a hot-melt film or a hot-melt bowl. All of these fall under the category of hot glue.
2、Their application ranges differ.
If using the cold glue method, which is suitable for most wall coverings, you need to thoroughly clean the wall surface. Then, apply the adhesive evenly to the wall using a roller, wait for 5 minutes, and then attach the wall covering. Additionally, remove any excess adhesive from the seams.
When using heat-activated wallpaper, it is typically used for seamless wallpaper applications. First, the heat-activated adhesive should be applied to the back of the wallpaper, followed by removing the release paper and adhering it to the wall. Finally, the wallpaper should be heated using a heat gun to melt the adhesive and create adhesion.
3、Construction method differences
Therefore, due to their different application scopes, the construction methods also differ. Furthermore, there are differences in environmental performance. Cold adhesives primarily focus on environmentally friendly adhesives, while hot adhesives, due to the high temperatures involved in their production, accelerate the volatilization of harmful substances. once the product is formed, no harmful gases are produced. Therefore, hot adhesives are relatively more environmentally friendly.
Two. Is it better to use cold glue or hot glue for wall coverings?
From an environmental perspective, using hot melt adhesives is generally preferred, as it minimizes pollution during interior decoration. If you choose high-quality cold melt materials, they are also suitable. Therefore, it is best to avoid using low-quality wallpapers and low-quality hot melt or cold melt adhesives.
