Weatherometer-2000 hours (ASTM D4459-8-03)
Pot Life-9;4-10 hours depending on temperature.
Cure Rate-(18-24) hours to touch;48-54 hours to walk on and 3-7 days full cure.
Liquid Roof and Liquid Rubber need temperatures above 55 degrees to cure. The temps can go below 55 but the product will not begin curing again until the temp's go above 55 degrees.
Chemical Resistance-Cured EPDM rubber is resistant to acids, alkalis and polar solvents
Cure system-Two-component Peroxide initiated
Heat Resistance 302 degrees F (150 degrees C)

Physical Properties
The physical properties of Liquid Rubber(R) are typical of its EPDM chemistry. The outstanding characteristics include:
Extreme high resistance to penetration of water. Ultra Violet and Ozone stable. Excellent long term aging properties.
Very broad temperature tolerance range (from 300 degrees F to minus 62 degrees F). Acid and alkali resistant
Withstands ponding water even when not cured
Spreading Rate A 20 mil dry film will result when liquid is applied at the rate of 42 sq. ft per gallon on a smooth surface.
A rate of 45 sq. ft allows for average roughness.
Weight/gallon 8 pounds (mixed)
Tensile 680 psi
Elongation 180-200%
Brittle Point -62 degrees F
