Technical Information on liquid roof

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, alkalies and polar solvents Cure system-Two-component Peroxide initiated Heat Resistance 302 degrees F (150 degrees C)

Mixing Liquid Roof With The Catalyst
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.

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.

Liquid Roof; a true EPDM rubber
Liquid Roof is a true EPDM rubber and is the only one sold in liquid form. Liquid roof makes installations easy. Liquid Roof could be described as a liquid version of the single ply EPDM membrane which has established and outstanding performance record of over 30 years. The EPDM chemistry has two unique features not possessed by any other rubber. It is unaffected by ultra-violet and ozone, and can tolerate continuous exposure at temperatures over 300 degrees F. The latter feature of liquid roof is also what gives EPDM rubbers the best aging properties (retain flexibility longer) of all elastomers.

Liquid Roof Application
Liquid Roof's one-coat application saves you time and money sealing and protecting your roof from roof leaks. Easily applied over Metal, Rubber, Fiberglass, Concrete, Fabric and Foam! No primer or top coat needed. Liquid roof can be applied with a paint brush, roller or squeegee. Liquid Roof liquid rubber is super-strong and waterproof, and is able to survive tremendous temperatures of warmth and chilly.

Liquid Roof Features
Some of the unique benefits of the liquid roof are:

• Can be applied over all roofing materials;
• UV and ozone resistant;
• Excellent against ponding water;
• Waterproofs IMMEDIATELY;
• Not damaged by freezing and has long term flexibility;
• Final cured properties not damaged by adverse conditions;
• ONE coat application.
