Function of dry glue: Only a thin layer of glue is needed, and high polymerization can be produced by using the atmospheric humidity in the air to achieve the best bonding effect. There are natural adhesives and synthetic adhesives, as well as organic adhesives and inorganic adhesives. It is mainly composed of base material+curing agent+filler+plasticizer+toughening agent+diluent.

Extended data:
Three-second glue can be used to collect evidence, which is called three-second glue method, that is, cyanoacrylate gas reacts with water and amino acid molecules to produce fingerprints.
How to use glue:
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. It can be used without stirring after the can is opened, so as to avoid air being stirred to form bubbles, resulting in joint surface defects. 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. When bonding, glue should be coated on one side first, and then the other side should be bonded.
4. Wipe the container after use, cover it, and store it in a cool and dry place or refrigerate.
Scope of application: It is specially used for bonding crystal to crystal and crystal to glass, and is typically used for bonding products in industries such as industry, glass handicrafts and crystal handicrafts.
When using, pay attention to thin and uniform sizing. Products should be stored in a cool and ventilated place, packaged in a dark place and protected from direct light. The product should be stored in a cool and dry place to avoid contact with sunlight or ultraviolet rays, and the bottle mouth should be sealed after use. The unopened original product can be stored at 25℃ for more than eight months. This product does not contain any pathogenic substances. If temporary redness is caused by careless contact with the skin during use, it should be washed with soap.
