2.
1.Check the substrate before gluing, make sure free of oil stains, water stains, dust, volatile substances, etc.; check the spray gun, make sure nozzle is clean so that to spray glue smooth;
2.Filter the main glue first, then mix with the hardener with ratio 100:5, the speed of the dispersing machine is about 500r/min, and after stirring for 5- 10min, a uniform blue glue solution is formed.
3.Use a pneumatic spray gun to spray glue evenly on the surface of the substrate, the amount of glue is about 80-140g/m2.
4.Put the glued substrate in a 60°C oven or drying tunnel for 5-10 minutes, then coating while hot.
5.Put the fitting sample into a constant temperature room (23 ± 2ºC, 50%RH) for 72 hours, and it can be used or tested.
6.After the gluing is finished, use the running tap water to clean the spray gun and the storage tank in time, not overnight.
7.The glue that has been mixed with the hardener should be used up within 4-6h. The main glue without hardener can be sealed with a barrel lid and placed in a constant temperature warehouse at 5-35°C, which can be used the next day.
If it is PP/PE and other difficult-to-stick substrates, it must be treated with flame or plasma before gluing.
