Chloroprene Based Adhesives

Solvent selection and adhesive solids will vary depending upon end use and method of application. The selection of the grade of polychloroprene and the tackifier allows the adhesives formulator to design products having specific properties, such as long or short tack or open time, controlled development of ambient- and/or elevated-temperature bond strength, and ultimate peel and shear strength. The cured adhesives are generally resistant to heat, oxidation, water, solvents and other chemicals.

Resins are also used in polychloroprene contact adhesives, the most common being the alkyl phenolic resins , terpene phenolic resins, rosin-modified phenolic resins, rosin esters, and hydrocarbon and coumarone resins .These substances have little effect on the final crystallizing of polychloroprene but improve adhesion ,  oxidative stability characteristics.

adhesives based on chloroprene exhibit performance advantages in a wide variety of related applications where quick, high-strength, permanent bonds are needed. A significant advantage of contact adhesives is auto-adhesion, which results in an instant bond with sufficient green strength so that fixturing is unnecessary.
