DESCRIPTION AND RECOMMENDED USES: 100% solids, Dura-Coat Membrane 910 is a high-elongation hybrid urethane elastomer. It is ideal for tank chimes and is fully compatible with metal, concrete, and other substrates. The elastomer provides high strenght and flexibility, while ceramic reinforcement enhances abrasion resistance. Membrane 910 can be easily applied by brush up to 40 mils without sagging.

Surface Preparation
Proper surface preparation is vitally important to the long-term performance of Dura-Coat Membrane 910. The surface should be clean and rough. Prepare with mechanical cleaning with a rotation wire brush. Clean with solvents (acetone, xylene, alcohol or MEK) and a cloth. No primer is required, Dura-Coat Membrane 910 is applied directly to metal or concrete.
Mixing
Mix the activator well into the base with the mixing rod scraping down the sides and bottom of the container. Mix by weight 6 part Base with 1 part Activator. Mix thoroughly to produce a uniform, streak-free material. Never put solvents.
Application
Dura-Coat Membrane 910 can be applied by brush.
To avoid sagging on vertical surfaces, the maximum thickness per layer should be up to 1mm (40 mil) per layer.
