This kind of situation usually occurs in besmear closed graph.Slow response speed, glue coating machine can't matching with glue, the environment temperature is too high, the workpiece is bigger, will be the beginning and the end of the match when the reason cannot be caused by a very good fusion.
1, selection of good quality and fast coating equipment.

2, selection process to adapt to the glue, and the first response is slow, after a period of fast reaction of glue.
3, according to the characteristics of glue for reasonable coating parameters setting, make the glue in the beginning and the end of the perfect fusion.
4, when the glue need to master the response time of the glue and glue the requirements of the work to adjust the factors such as temperature, humidity.
Dalian showed the automatic polyurethane sealing glue of production equipment, combined with the unique raw materials and coating technology, to ensure the sealing strip is beautiful, joint are basically identical.
