502 glue in the process of using several key points

        502 glue is mainly composed of α-cyanoacrylate, which is a one-component instant curing adhesive. Due to its fast bonding speed and strong bonding, it should be used with special care to avoid improper operation. unnecessary trouble. Adding a tackifier, a stabilizer, a toughening agent, a polymerization inhibitor, etc., a one-component instant curing adhesive synthesized by an advanced production process.

Curing principle: The polyaddition reaction occurs under the catalysis of trace water in the air, and it is rapidly solidified to adhere the adherend. 502 glue bottle.

Product features: If the product is exposed, it is exposed to traces of water vapor in the air, which is characterized by rapid polymerization and solidification. Therefore, it is called instant adhesive. This product is widely used in steel, non-ferrous metals, non-metallic ceramics, glass, wood and flexible materials like rubber products, leather shoes, soft and hard plastics, etc., but also for polyethylene, polypropylene, polytetrafluoroethylene. A difficult-to-bond material such as ethylene, whose surface needs special treatment before it can bond.

  Instructions:

1. Before use, clean the surface of the adherend to remove dust, oil, rust, etc. on the surface. When bonding metal, it is best to grind it first. When bonding PE, PP and other plastics, first make it Surface activation.

2. Open the front cover of the glue bottle and gently buckle the tip of the finger so that there is no residual liquid, then cut the hole with scissors.

3. Drop a small drop of this glue on the surface of the adherend, and immediately bond it until it is hardened. Of course, the bonding area should not be too large.

4. Wipe the glue bottle after use and cover it tightly, store it in a cool dry place or refrigerate.

Use 502 glue should pay attention to:

1. The thinner the rubber layer is, the higher the strength is. The coating area of 0.02g glue should be 8-10 square centimeters.

2. Control the best closing time. After applying the glue, it should be left open for a few seconds, so that the rubber layer absorbs a small amount of water and then closes. If the glue is closed immediately after application, the bonding will fail.
