■Apply

Mainly used in PCB circuit board, electronic control board, industrial control board, instrumentation, industrial semiconductor crystal circuit board, protect the role of electronic parts, small home appliance circuit board, automotive circuit board light. LED photoelectric aluminum substrate and other electronic industry bonding.■Technical features

(At TA=25℃、RH：50%)

 Note: The curing data of the above products are 25 C, 50 ± 5% relative humidity, and obtained after 7 days of curing.

■Use method and matters needing attention

※Use method and matters needing attention：

① Pour the protective paint into the immersion bucket and apply it. The immersion speed of the circuit board or components should not be too fast to avoid generating bubbles. The best baking temperature is between 80℃ -10O ℃ for 3-5 minutes. Normal temperature curing 5~15 minutes table dry, full curing time within 24 hours. ② After the coating, if there is remaining protective paint, it can be poured back to the empty container, Keep sealed and use up as quickly as possible; use again, if The surface crust removes the epidermis without affecting the performance of the product, Can continue to use.

※Spray process：

① Dilute the protective paint with a special diluent, add a large amount of diluent, The viscosity of glue is low and the thickness of glue is thin; otherwise, the viscosity of glue is high The thickness of the glue is thick. The amount of diluent is recommended to be 10 to 20%. ② Put the diluted glue into the spray can for spraying. ③ After the spraying, clean the watering can with the diluent.

※After pouring out the glue in the container, wipe the glue at the mouth of the bottle and tighten the bottle Cover, sealed in a cool place. When used again, if there is a little at the mouth of the bottle Skin, it can be removed, does not affect the normal use.

※This product is a non-dangerous goods, but do not enter and eyes.
