Surface tension: 39 dyne/cm. Polymer type: High gel. Emulsifying agent: Sodium rosinate. Moderate crystallization rate.Wet Gel Properties: Medium tensile strength. Medium elongation. Fast cure rate. Low modulus.General Neoprene Latex Information: Neoprene latexes are aqueous colloidal dispersions of polychloroprene or of copolymers of chloroprene with other monomers such as methacrylic acid or 2,3-dichloro-1,3-butadiene. They are available in both anionic and nonionic surfactant systems. All neoprene latexes have a unique combination of inherent characteristics including excellent film formation; high cohesive strength without curing; elastomeric properties over a wide temperature range; and considerable resistance to degradation from chemical or environmental exposure. Uses include adhesives, binders, coatings, dipped goods, elasticized asphalt and concrete, and foam.Information provided by DuPont Dow Elastomers.This former DuPont Dow Elastomers product line is now produced by DuPont Performance Elastomers.
