Claims20
A method of making a latex dispersion comprising:
- providing a rubber component comprising polyisoprene, and
- combining the rubber component with a vulcanization composition comprising at least one fugitive dihydrocarbyl xanthogen polysulfide accelerator and at least one aldehyde-aniline condensate.
A coating composition for an elastomeric article, comprising:
- a latex dispersion comprising:
- polyisoprene, and
- a vulcanization composition comprising a source of sulfur, diisopropyl xanthogen polysulfide, heptaldehyde-aniline, and a metal oxide;
- a second polymer latex selected from the group consisting of natural rubber, polyurethane, polybutadiene, polychloroprene, nitrile rubber, block copolymers of styrene and butadiene, block copolymers of styrene and isoprene, and synthetic polyisoprene;
- and
- water.
