Universal Glue Basic Concept

Universal glue usually refers to building decoration and hardware maintenance industry, a common type of solvent-based adhesives, because of its wide range of bonding, easy to use and named, generally can be used for wood, aluminum plate, leather, artificial leather, plastic, rubber, metal and other soft and hard materials bonding. The main components of the common adhesive are neoprene, benzene, toluene, xylene as a solvent, yellow liquid viscous, with good oil resistance, solvents and chemical reagents performance.

Universal gum Chemical named "Cyanogen acrylate", in 1942 by Harry Wesley Couves invention. Coover's team initially wanted to develop an item to clean the gun's sights, but the compound was abandoned for research because it was always glued to all the objects, but coover this feature and launched the adhesive sale in 1958.

"The father of adhesive."

Universal glue is actually neoprene adhesive commonly known as. Neoprene is prepared by emulsion polymerization of chloroprene rubber:

nch2=ch-ccl=ch2→ (CH2-CH=CCL-CH2) n

In the polymer molecular chain 1, 4-trans structure accounted for more than 80%, the structure is more regular, coupled with the presence of polar chlorine atoms on the chain, so the crystallization of large, in -35℃-32℃ can crystallization (to 0 ℃ as the fastest). These properties make neoprene at room temperature even if not vulcanization has a higher cohesion and better adhesion properties, is very suitable for use as adhesives. In addition, because of the presence of chlorine atoms, neoprene rubber mold has excellent characteristics of flame resistance, ozone resistance and atmospheric aging resistance.
