What is thermal transfer glue

1 What is thermal transfer glue
Thermal transfer glue is another name for thermal transfer adhesives and adhesives in the thermal transfer industry. Its actual component is a hot melt adhesive.

A. Hot melt adhesive is a plastic adhesive. Its physical state changes with temperature within a certain temperature range, while its chemical properties remain unchanged. It is non-toxic and odorless and is an environmentally friendly chemical product.

B. Thermal transfer glue inherits the non-toxic and odorless chemical properties of hot melt adhesive, which greatly promotes the popularization and promotion of the use of thermal transfer technology.

C. As a direct contact with the substrate during the thermal transfer process, the quality of thermal transfer glue directly affects the final quality of the thermal transfer process. Therefore, thermal transfer glue plays a vital role in the entire thermal transfer process.

2 Thermal transfer glue adhesion effect
So, how to ensure that the thermal transfer glue and the substrate can completely match and achieve a perfect adhesion effect?

A. In the production process of thermal transfer printing film, the resin selection of thermal transfer glue must be carried out according to the resin properties of the final workpiece (substrate), because only when the resin properties of the substrate are completely matched with the resin selection of thermal transfer glue, can the thermal transfer glue and the substrate be tightly bonded, and the pattern can be firmly attached to the substrate, thus presenting a perfect thermal transfer effect.

B. For example, if the resin of the substrate is acrylic acid, then the resin selection of thermal transfer glue must be acrylic resin; if the resin of the substrate is polyethylene, then the resin selection of thermal transfer glue must be polyethylene resin; although the resin selection of thermal transfer glue is extremely wide, matching with the resin properties of the substrate is the basic principle.
