Abstract

A powder-free coagulant for use in latex dipping processes comprises a salt stable dispersion of a polychloroprene rubber and an inorganic metal salt. Optionally the coagulant will also contain a powder-free release agent, to aid release of the dipped article from the former, comprising a polypropylene wax emulsion and a cationic surfactant.
