This product is a polyurethane structural glue with one component of UV+moisture curing, free of any solvent and volatile matter, with short positioning time and extremely strong initial curing strength, which can effectively improve production efficiency and save pressure retaining fixtures. After curing, the gel has good flexibility and high and low-temperature resistance. It is suitable for bonding plastic/plastic, plastic/metal/glass.
Typical applications
Applications include bonding of smart phone touch screen and shell, bonding of notebook shell, bonding of portable device battery shell, bonding of touch screen shell, bonding of other electrical screens and shells, etc

Operation
The surface of the gluing workpiece must be free of grease or dust. It is recommended to use a suitable solvent for surface treatment of the workpiece. When dispensing, heat it to 110 ℃, and then wait for 10-15 minutes before formal use. After the glue is applied to one of the two workpiece to be assembled, the other workpiece to be assembled shall be fixed to the workpiece with glue by pressing fixture or fixture within the opening time of glue until the bonding surface reaches the corresponding assembly strength. The curing time of glue is affected by the temperature and humidity of the environment and the material type of the workpiece.
Surface treatment
Plastic: Clean the plastic surface with a cotton cloth dipped in isopropyl alcohol, and glue it after the solvent volatilizes. When the plastic surface is polluted by the mold release machine, it needs to be treated with isopropyl alcohol and polished with fine gauze. After the solvent volatilizes, it can be glued.
Metal: clean the metal surface with cotton cloth dipped with butanone, polish it with fine gauze, and glue it after the solvent volatilizes.
Glass: clean the metal surface with cotton cloth dipped with butanone, polish it with fine gauze, and glue it after the solvent volatilizes. Under the condition of high heat/humidity, the primer treatment shall be considered.
Packing
30ml syringe, aluminum foil bag
Term of validity
It can be stored for 6 months at 5~25 ℃ under the condition of intact packaging.
