Solvent-free adhesive is a kind of polyurethane adhesive, which can be one-component or two-component adhesive. Simply put, it can realize the adhesion and connection of media under solvent-free conditions. It is a green and environmentally friendly adhesive that can be used for food packaging and other potential adhesives.
The traditional polyurethane glue is mainly solvent-based. Because it uses a lot of solvents in the compounding process, solvent residues will be generated during the compounding process, which is not conducive to the safety of food packaging. Solvent-free can solve the problem of solvent residues. With the enhancement of national regulations and environmental protection awareness, the use of solvent-free will become more and more widespread. It will not only be used in food packaging, pharmaceutical packaging, but also be used in many fields such as car stickers, furniture, and so on. Solvent-free in terms of cost Compared with the dry composite process, the composite apartment can save about 20-30% of the cost.
General-purpose compound glue
It can be applied at room temperature and is resistant to boiling
Resistant to cooking and solvent-free laminating adhesive
Coating at 45-55 degrees, it can be resistant to cooking after curing, but it needs to be coated twice.
Solvent-free laminating adhesive for aluminum foil
The title can be used for the compounding of aluminum foil. Because the compounding of aluminum foil is difficult, there is no mature technology in China. The usual solution is to use the principle of light curing to make it fast curing.
