PUR (Polyurethane Reactive), the full name in Chinese is moisture curing reactive polyurethane hot melt adhesive. It is heated and melted into a fluid for easy application. After cooling, it gels for bonding. It is non-toxic and odorless, and is an environmentally friendly chemical product.

Structural adhesives are generally solvent-free two-component PUR adhesives. This two-component structural adhesive can cure quickly and improve productivity. Its mechanical properties such as strength and elongation can be adjusted and designed according to user requirements to meet higher requirements. Glass glue is also a kind of structural glue and has viscosity without heating. Whether the pur glue machine can be applied to structural glue materials, I believe everyone has their own judgment.

PUR hot melt glue machine has air pump type and gear pump type according to the glue supply method, and has the melt cylinder type and pressure plate type according to the sol method.
