How to use 502 glue and matters needing attention
1. First clean the bonding surface to remove dust, oil stain and rust. When bonding metals, it is best to grind them first. For plastics such as polyethylene, polypropylene or PTEE, the surface should be activated first.
2. Open the front cover, gently buckle the tip with your fingers so that there is no residual liquid, and then cut out the hole with scissors.
3. Drop a small drop of adhesive on the surface to be bonded, then do it immediately and keep it until it becomes hard. The bonding area should not be too large, and the thickness of the bonding layer should not exceed 0.2 mm. ..
4. Wipe the container after use, cover it, and store it in a cool and dry place or refrigerate.
Principle: Under the catalysis of trace water in the air, the polyaddition reaction takes place, which quickly solidifies and sticks the adherend firmly. 502 brings convenience, and sometimes things that you don't want to post will accidentally stick. The removal methods are: 502.
1. Drop banana oil on the glue stain and keep stirring with an old toothbrush. When the glue stains become soft and fall off, rinse them with clear water and brush them repeatedly until they are clean. Stick absorbent cloth on the back of the clothes with glue marks, then coat some white vinegar on the glue marks, and finally scrub them with cotton dipped in water.
2, with insulating oil, pour the insulating oil in the transformer on the table, 502 glue will soon become soft and can be wiped off quickly.
3, 502 glue is a resin glue, as long as you use an organic solvent that can dissolve the resin, such as acetone. However, inhalation of acetone is toxic, so attention should be paid to its use. You can stuff the sticky part into the bottle. It is said that the glue will fall off if it is frozen in the refrigerator. You can try it first.
4. Stick 502 glue on a small area and soak it in hot water. If 502 glue is stuck on a large area and acetone is coated, it can be removed in about 5 ~ 10 minutes.
5, recommend acetone, gasoline, sesame oil, etc. Pour some insulating oil from the transformer on your hand, and the 502 glue will soon become soft and easy to erase.
