Aquastik 2540 neoprene Dupont Dow Elastomers Rubber - Elastomer >> Chlorinated rubber / Chloroprene, CR ADHESIVE A high solids, anionic, aqueous dispersion of a medium-gel Neoprene® polymer used primarily for adhesive applications. Storage stability is good. However, pH decreases with time, the rate depending on temperature and air exposure. This decrease is indicative of structural changes in the polymer and of alterations in the colloidal properties of the latex which are not readily measured. To keep changes at a minimum, it is recommended that inventory be kept low and that the latex be stored at temperatures between 13 and 21°C (55-70°F) with as little contact with air as possible. High solids, anionic, aqueous polychloroprene dispersion used for adhesive applications. Provides good storage stability. pH decreases with time.
