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.
Adhésif de contact au polychloroprène composé d'un mélange de polychloroprène, d'un agent collant, d'oxyde métallique, d'antioxydant et de solvant organique. L'adhésif est cisaillé de manière à en réduire le degré de viscosité Saybolt (ASTM D 1804 ) d'au moins 10 p cent, ce qui facilite la pulvérisation de l'adhésif de contact au polychloroprène, tout en uniformisant et réduisant la viscosité.
