Abstract:
1. A cross-linked ethylene propylene diene terpolymer latex with a solids content from 30 weight percent to 60 weight percent based on the total weight of the cross-linked ethylene propylene diene terpolymer latex, the cross-linked ethylene propylene diene terpolymer latex comprising: a. 15 weight percent to 88 weight percent of a premixed liquid ethylene propylene diene terpolymer component in 50 weight percent to 96 weight percent of a solvent, wherein the premixed liquid ethylene propylene diene terpolymer component has a molecular weight from 1300000 Mw to 5000 Mw, and consists of: b. 10 weight percent to 70 weight percent of a water, wherein the water is selected from the group consisting of: distilled water, deionized water, tap water, process water, and combinations thereof; c. 1 weight percent to 30 weight percent of a surfactant; and d. at least a portion of at least one of: a sulfur donative curative and a free radical generating curative, wherein the portion is within a weight percent from 0.3 weight percent to 1.76 weight percent of a total amount of curative used in the formulation, thereby forming a cross-linked ethylene propylene diene terpolymer miscible with acrylic, urethane, alkyd, and epoxy lattices; and
