high modulus polychloroprene homopolymer made in

Neoprene 671A liquid dispersion (LD) contains a high modulus polychloroprene homopolymer made in
an anionic colloidal system.
Features :
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.
Suggested End Uses
-Dipped goods
-Construction mastics
-Laminating adhesives
-Extruded thread
-Impregnated paper
-Bonded batts
-Contact bond adhesives
