Some Technical Information on Liquid Roof and Liquid(R)

pricing_canimage

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)

Mixing The Catalyst With Liquid Roof

 

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

Cure Mechanism-This rate is determined by temperature and the availability of oxygen. Oxygen is necessary to activate the catalyst, which promotes peroxide decomposition at lower temperatures. The cure mechanism in EPDM Liquid Rubber(R) will vary from active to inactive determined by temperature. Broad day-night temperature swings in spring and fall will not compromise the final physical properties of the Liquid Rubber(R) membrane.

      Overall, I am impressed with the results I obtained in using Liquid RV roof on my trailer. It was MUCH easier than replacing the membrane with new, and seems to have repaired my leaking roof, extending the life of my RV, as at some point, the cost of reroofing would exceed the RV’s value. Thanks in advance!

      My roof was in bad shape. I cleaned it and kept after it a few times a year. We bought the RV used, and there were signs of neglect when we bought it. It had been obviously sitting in the sun for an extended period of time without any care or maintenance. I was about to buy a sheet of EPDM and forego the labor intensive and very expensive task of replacing the sheet roof. Then I saw a video on Youtube for Liquid EPDM. So the research began. “This… Read more

      I was able to quickly find the 2 pictures I took after I patched the roof. I will continue to look for the before pictures, We have a flat roof with a channel down the middle that leads into a drain pipe system that has been our weak point area all along. Then we installed a sky light which was like adding gasoline to a fire. For years I was blaming the sky light that we installed. We even replaced portions of the sky light and sealed around it many… Read more

      The two pictures are the before and then after using your product Liquid Rubber. Very pleased with the way it turned out! And also the shipping sure came quickly. Have a great and safe day! Bob & Sally H.Yuma AZ

      The epdm rubber roof was easy to work with. I am very pleased after having a leaky roof that will be good for many years to come. Roof had mold on it so we first killed the mold with Clorox and water and scrubbed I down and then cleaned the roof with Dawn dish detergent. Attached are the before and after pictures. ThanksRick M.
