Neoprene 571 neoprene Dupont Dow Elastomers Rubber - Elastomer >> Chlorinated rubber / Chloroprene, CR ADHESIVE Neoprene 571 liquid dispersion (LD) A medium solids, anionic dispersion of a high-gel Neoprene polymer whose vulcanizates exhibit high tensile strength. It is used in dipped goods, adhesive coatings and elasticized concrete 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 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 (55) and 21°C (70°F) with as little contact with air as possible. Medium solids, anionic polychloroprene dispersion used in adhesives. Exhibit high tensile strength. Provides good storage stability. pH decreases with time.
