Mixing the Catalyst with Liquid Rubber

When EPDM rubber is chemically resistance-cured, it resists polar solvents, alkalis and acids. The cure system includes a two-component peroxide heat resistance that becomes initiated at 302° F.

Physical Makeup

EPDM Liquid Rubber is very similar to traditional EPDM makeup. The most crucial qualities include:

• A high resistance to water, ozone and ultraviolet stability, and overall fantastic anti-aging characteristics for many years.
• A temperature tolerance that ranges from -62° to 300° F.
• It’s is both alkali and acid resistant.
• Holds up against ponding water even before it’s fully cured.

What’s the Spread Rate?

The ideal thickness is 20 mil. of dry film, which can be spread to 42 square feet per gallon onto a smooth area. When assuming a 45 square foot gallon, the specs are:

• 8 pounds per mixed gallon
• 680 psi tensile
• 62° F brittle point
• 180-200% elongation

What’s the Cure Rate?

The quickness of curing depends wholly on temperature and oxygen availability. Oxygen is required in order to activate the catalyst. Keep in mind that temperatures vary drastically in some regions, and it may take several weeks for a full cure to take place if EPDM Liquid Rubber is applied during a cool season. However, even in a non-cured state, it will withstand water and rainfall.
