It is a special accelerator for CH-type and W-type chloroprene rubber and chlorohydrin rubber and polyacrylic acid vinegar rubber products. Used in wire, cable, rubber, tube, rubber shoes, rain boots, raincoats, etc., also used in fine chemical crystal intermediates, antioxidants, insecticides, dyes and synthetic resins.

Neoprene has a relatively regular structure and a relatively polar chlorine atom, so it has high crystallinity, which makes it have good bonding properties and large cohesive strength at room temperature. It is very suitable as an adhesive, chlorine. 

The characteristics of the adhesive are as follows:

1. The initial adhesive force is large. Most of the neoprene adhesive is a room temperature curing contact type. It is glued to the surface. After being properly dried, it can be instantly crystallized after being closed and has a large initial adhesion.

2. The bonding strength is high and the strength is established quickly.

3. It has good adhesion to a variety of materials, so neoprene adhesives are also known as "universal glue".

4. Good durability, excellent flame retardancy, light resistance, ozone resistance and atmospheric aging resistance.

5. The rubber layer is flexible, elastic, and resistant to impact and vibration.

6. Good resistance to medium, good oil, water, alkali, acid and solvent resistance.

7. It can be combined into a single component, easy to use and low in price.

8. Poor heat resistance and poor cold resistance.

9. Solution-type neoprene adhesive is slightly toxic.

10. Poor storage stability, easy to stratify, gel, precipitate.

11, neoprene can achieve polymerization temperature controllable
