9700 - Novolac Coating and Lining

Rhino™ 9700 Novolac is a high quality Bis-F epoxy novolac coating and lining system which has superior chemical and abrasion resistance versus Bis-A type epoxy resins. This tightly crosslinked epoxy system cures in the presence of moisture and humidity with excellent mechanical properties.

Rhino 9700 mixes using the industry standard, 2:1 by volume ratio. Having low odor, Rhino 9700 contains no solvents and is 100% solids that assures ease of application. Rhino 9700 Novolac viscosity is well suited for vertical applications.

Mixing

A thorough and complete mixing is critical. First mix each component separately. Proportion each component at the ratio of 2 parts A (resin) to 1 part B (hardener) by volume or if using 1-gallon kits, pour all of Part B (hardener) into Part A (resin). Mix for 3 – 5 minutes, scraping the mixing container sides and bottom regularly. Mix no more material than may be applied in 20 minutes.

Tank Linings and Secondary Containment Coatings

Apply mixed product by brush or roller at the rate of 15 mils (approx. 100 sq ft per gallon). Once the first coat has tacked, but not fully cured, an additional 15 mil coating may be applied. Allow the material to cure 48 hours minimum before exposure to any chemicals (product will continue to cure for 7 days to full properties).
