Uroflex

Product Description

Uroflex possesses the advantages of both a polyurethane and epoxy together as one technology, while incorporating novolac- exhibiting superior adhesion, tolerance and strength of an epoxy, yet combined with the flexibility (38% tensile elongation), gloss, and impact resistance of a urethane.  The epoxy resin incorporates novolac, thus enhancing its chemical resistance and crosslinking.

Uroflex is CIGMAT tested by the Department of Civil and Environmental Engineering at the University of Houston for construction and rehabilitation of civil infrastructure, undergoing a battery of modified, specific industry testing.

This hybrid technology is unique and proprietary, allowing for a coating with outperforming protective corrosion resistance. Uroflex is formulated “green,” environmentally friendly, 100% solid (no VOCs, no solvent). The Uroflex coating system is easy-to-apply by spray, brush, or roller. Conveniently mixes in a 1-to-1 ratio by volume. Uroflex self-levels, and can be applied up to 65 mils per coat. For long-term maintainability, the Uroflex system ties back into itself indefinitely with no need for re-blasting or abrasion.

Typical Uses

Uroflex has been proven in many aggressive enclosed, immersive, and partially opened environments. Uroflex performs in areas subject to chemical attack.

Ideally suited as a protective coating/lining solution for:

  • Collection and treatment structures, tanks, pipes, stations, manholes, etc.
  • Joint sealing
  • Seamless and sealed coating & lining
  • Protection against corrosion for steel, concrete,wood and other substrates
  • 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/NACENo. 6,“Surface Preparation of Concrete;”with an ICRI CSP profile of 3-5. 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.

Wood: Remove all grease, oil, dirt or other foreign matter by solvent or detergent washing. Prepare wood surface by abrasive sanding and washing (allow to dry and prime using an Epoxytec recommended primer).

Application Method

Mix 1‐to‐1 by volume and be aware ofpot life (higher temperature and mass accelerates pot life). Options:Brush, rollers, squeegee, airless/air‐assisted airless, and/or plural component spray airless/air‐assisted airless equipment. Heated lines and guns could be used, but not required.When possible, Epoxytec recommends Uroflex™ 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.Other options available: Epoxytec EZ-Spray System (disposable cartridge spraying).

Film Thickness

Uroflex can be a single coat or multiple coat system.Uroflex can be applied onto a cementitious surface at 15 mils (minimum) to 25 mils (maximum by roller/brush) or 65 mils (maximum by spray) per coatat 77F. For a total coating thickness exceeding 25 mils (by roller/brush) or 65 mils (by spray), multiple coats are necessary.Uroflex™ can be applied onto a metallic surface at 8mils (minimum) to 15 mils (maximum by roller/brush) or 25mils (maximum by spray) per coatat 77F. For a total coating thickness exceeding15 mils (by roller/brush) or 25mils (by spray), multiple coats are necessary.Note: Uroflex™ has self-leveling properties and will pull back from profile peaks and settle into the valleys as it levels; therefore, if the substrate has peaks, take precautions as edge retention may prove challenging

Uroflex

Epoxytec Uroflex is a truly unique hybrid epoxy coating- 100% solid, medium to high build, urethane-modified-epoxy (UME) coating and liner enhanced with novolac.

Uroflex is a urethane‐modified‐epoxy (UME) coating, incorporating novolac resin for enhanced chemical resistance and crosslinking. It possesses the superior adhesion, tolerance and strength of an epoxy, combined with the flexibility (38% elongation), gloss, UV tolerance, and impact resistance of a urethane‐ combined as one technology.

Uroflex is applicator friendly and easy to apply by brush, roll, or spray; conveniently produced as a one‐to‐one mix ratio by volume. Uroflex is “green” formulated, environmentally friendly, 100% solid (no VOCs, no solvent).

Uroflex has been designed to specifically protect, seal, and outperform in environments, whether immersed or non-immersed, which are susceptible to movement, corrosive exposure, microbial and chemical attack, joint infiltration, vibration and impact, while being tolerant to high levels of moisture and humidity during application.
