Abstract
Delayed action setting of a composition comprising an anionic latex of a film forming polymer by addition of a delayed action setting agent characterized in that the setting agent is a compound containing a multivalent metal cation having defined solubility characteristics in a quantity not greater than 2.5% wt/wt on total composition and not greater than 11% wt/wt based on film forming polymer solids in the composition.
Claims14
A process for the delayed action setting of a composition comprising adding to anionic latex of polychloroprene a delayed action setting agent compound containing a multivalent metal cation, which metal cation compound has a solubility in the range 0.1 g to 150 g per 100 g of water at 20.degree. C. in water and which has a dissolution time greater than 1 minute, the quantity of metal cation compound being not more than 2.5% by weight based on the total weight of composition and not more than 11% based on the weight of polychloroprene solids in the composition.
