Claims
- 1. A powder-free coagulant composition for natural and synthetic rubber latex wherein the coagulant composition comprises an aqueous, salt stable polymer dispersion, at least one inorganic metal salt and a wax component.
- 2. A powder-free coagulant composition for natural and synthetic rubber latex wherein the coagulant composition comprises an aqueous, salt stable polymer dispersion, at least one inorganic metal salt and a cross-linking agent to cure the salt stable polymer.
- 3. A powder-free coagulant composition according to claim 2 wherein the cross-linking agent is selected from the group consisting of aqueous based dicarboxylic and tricarboxylic acids, polyamide resins, melamine formaldehyde resins and mixtures thereof and further wherein the cross-linking agent is present in an amount between about 3% and 15% by weight of the coagulant composition.
- 4. A powder-free coagulant composition for natural and synthetic rubber latex wherein the coagulant composition comprises an aqueous, salt stable polymer dispersion, at least one inorganic metal salt, and a detackifying agent essentially free of silicon emulsion, wherein the detackifying agent is a surfactant is selected from the group consisting essentially of quaternary surfactants, amphoteric surfatants, triquternary phosphate esters, betain derivatives and mixtures thereof and further whrein the surfactant is present in an amount between about 0.5% and 15% by weight fo the coagulat composition.
- 5. A powder-free coagulant composition according to claim 1 wherein the wax compound is selected from the group consisting of low and high density homopolymers and copolymers, microcrystalline waxes, castor waxes, long chain fatty esters, paraffin wax, bees wax, polyamide wax and mixtures thereof and further wherein the wax compound is present in an amount between about 0.25% and 10% by weight of the coagulant composition.
- 6. A powder-free coagulant composition for natural rubber latex which coagulant composition comprises an aqueous polychloroprene dispersion, an amphoteric surfactant, a detackifying agent and an inorganic metal salt.
