Abstract:
1. A method for making a high solids low volatile organic compounds durable curable waterproof liquid rubber formulation with a solids content of at least 60 percent solids by volume of the total formulation, comprising: a. creating an ethylene propylene diene terpolymer component by: b. continuing to blend the low viscosity liquid intermediate rubber formulation at a low shear for 10 minutes to 12 hours at a temperature from 20 degrees Celsius to 50 degrees Celsius, forming the ethylene propylene diene terpolymer component; c. forming a catalyst component by blending in a closed vessel: blending together the ethylene propylene diene terpolymer component and catalyst component forming a blend, with a weight ratio from 250:1 to 10:1 of the ethylene propylene diene terpolymer component to the catalyst component, the blend adapted to cure on the substrate without addition of another curative, resulting in a high solids low volatile organic compounds durable curable waterproof liquid rubber coating with a solids content of at least 60 percent solids by volume, a tensile strength greater than 250 psi, an elongation greater than 50 percent, and a Shore A hardness from 40 to 70.
