​​​​​​​What is the difference in performance between PU oily and water based pu glue?

General water based pu glue is made by using water as a solvent to emulsify acrylic and polyurethane resins through specialized emulsification equipment. The biggest advantage of this kind of water-based glue is that it has many varieties, environmental protection and very low price. Generally speaking, the coating is water-soluble glue.

Oil-based coating adhesives are generally based on oil-based solvents and need to dissolve acrylic or polyurethane. This has the advantages of good film formation and fastness. PU is a hot air adhesive that is very common. Used coating glue.

However, the use of oil-based solvents will have environmental protection problems. Now the increase in oil prices may cause the price of oil-based solvents to rise all the way. Most coating adhesives are used because of the high cost, which leads to the use of poor oil-based solvents. Environmental protection is not up to standard.
