How to use:

1. The surface of the bonded material should be free of ash and oil, clean and dry, and can be polished with emery cloth if necessary. Acetone wipe, the better the effect, the cleaner the bonding surface, the stronger the bonding force.

2. First install the rubber hose on the special glue gun, unscrew the rubber cap in front of the rubber hose, pull the trigger of the rubber gun to discharge the air in the rubber hose, so that the glue in the rubber hose is uniformly discharged, and then assemble the mixing tube.

3. Pull the trigger of the glue gun, evenly apply the glue on the surface of the adhesive, scrape it flat, then superimpose pressure, gel at room temperature for 35-60 minutes, and can be delivered 24 hours later.

Note:

It may cause skin discomfort. If it comes into contact with skin, remove it with soap and water. If it comes into contact with eyes, rinse with water.

If swallowed, seek medical attention immediately. It contains epoxy and polyamide resins.
