Neoprene 671-A Neoprene Dupont Dow Elastomers Chlorinated Rubber Miscible in water Neoprene 671A liquid dispersion (LD) contains a high modulus polychloroprene homopolymer made in an anionic colloidal system. Wet Gel Strength Good wet gel elongation and wet gel tensile strength make wet films of Neoprene 671A resistant to gel cracking, either alone or in blends with other Neoprene LDs such as Neoprene 571 or Neoprene 842A. High Solids with Low Viscosity Neoprene 671A has a high solids content with a viscosity only slightly greater than that of conventional 50% solids Neoprene LDs. Coagulant dipping deposition rate is higher than that obtained with 50% solids LDs. coatings Dispersion of a high modulus polychloroprene homopolymer in an anionic colloidal system. Used in coatings. Offers good wet gel elongation and wet gel tensile strength. Possesses high solids content and low viscosity.
