  • Improving the sprayability of polychloroprene contact by shearing in microfluidizer
    Patent number: 5733961
    Abstract: Polychloroprene contact adhesive is made by mixing polychloroprene, tackifier, metallic oxide, antioxidants and organic solvent. The contact adhesive is sheared for reducing its ASTM D 1084 Saybolt viscosity by 10 percent or more. Shearing improves the sprayability of the polychloroprene contact adhesive. It makes it more uniform and reduces its viscosity.
