Uroflex HCN

Product Description

Epoxytec Uroflex HCN is an ultra-high chemical resistant formulation. The two-component polymer epoxy system is 100% solid, containing no V.O.C.s. Uroflex HCN is an ultra-high cross-linking novolac/aliphatic polyamine system with excellent resistance to chemicals and good surface properties. It is designed as a high-build coating for continuous immersion in aggressive environments where high chemical resistance is required. It has excellent resistance to concentrated sulfuric acid, as well as alkalis, and most solvents and hydrocarbons. Excellent smooth film, high gloss, impact resistance, blush resistance, chemical resistance, U.V. tolerance.

  • Other industrial lining and coating applications
Surface Prep

The success of any coating application is directly proportional to the completeness of the substrate preparation and the care the application crew puts into the application. Surface must be clean and sound. Remove all dust, contaminants, grease, curing compounds, rust, impregnation, waxes, foreign particles, and disintegrated materials from the surface, in order to achieve a clean and profiled surface.
Concrete: Prepare the concrete by abrasive blasting, high pressure water cleaning, and/or approved mechanical method to achieve clean, sound, and profiled concrete. Prepare concrete in accordance with SSPC-SP 13/NACE No. 6. “Surface Preparation of Concrete.”Although priming is not required, in some cases when suspecting excessive moisture vapor transmission (MVT), out-gassing, or other impediments – an Epoxytec recommended primer may be considered. Steel: Before preparing steel, please inspect and remove oil, grease, or other contaminants – “Solvent Cleaning” (SSPC-SP1) may be required. Remove all sharp peaks, including weld spatter. Abrasive blasting (or other approved mechanical methods) must be used in order to achieve a clean surface with a minimum profile of 3 mils. Stripe coat all edges and peaks with an Epoxytec recommended primer. To prevent flash rusting, consider the use of an Epoxytec recommended primer.

Application Method

Mix part A with part B. Proportion the components into a clean pall and mix for approximately 5 minutes with a “jiffy mixer” (or equivalent electric drill), on a low speed (400-600 rpm) drill until the color is uniform blend. When possible, Epoxytec recommends Uroflex HCN as a two-coat system. NOTE: If spraying, Epoxytec recommends at minimal the use of a .023” orifice spray tip or greater, 64:1 ratio spray pump or greater, 3/8” hoses, with 1/4” whip.

Film Thickness

Uroflex HCN can be a single coat or multiple coat system. Uroflex HCN can be applied onto a cementitious surface at 16 mils (minimum) to 30 mils (maximum by roller/brush) or 65 mils (maximum by spray) per coat at 77F. For a total coating thickness exceeding 30 mils (by roller/brush) or 65 mils (by spray), multiple coats are necessary. Uroflex HCN can be applied onto a metallic surface at 10 mils (minimum) to 16 mils (maximum by roller/brush) or 30 mils (maximum by spray) per coat at 77F. For a total coating thickness exceeding 16 mils (by roller/brush) or 30 mils (by spray), multiple coats are necessary.

Uroflex HCN

Epoxytec Uroflex HCN is a 100% solid, medium to high build,  novolac epoxy coating and liner.

Uroflex HCN is is an ultra-high cross-link, aliphatic polyamine novolac epoxy, formulated for ultra high chemical resistance. The material is often utilized to combat solvents, hydrocarbons, and various chemicals or volatiles often found in containment or secondary catch basins. As a primary liner, it can withstand industrial immersion applications and ultra-harsh environments.
