■Use method and matters needing attention

※Baptist process:

①Pour 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. After soaking, hanging and hanging, the normal temperature meter dry time is not longer than 40 minutes, as far as possible without heating and drying.

②After the coating, if there is any remaining protective paint, return the empty container, Keep sealed and use up as quickly as possible; when again, if The surface crust removes the epidermis without affecting the performance of the product, Can continue to use.

※Spray process:

①Dilute 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%.

②Apply the diluted glue into a spray can.

③After the spraying, clean the watering can with the thinner.

※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.
