CPP Sprayliner

Product Description

Epoxytec CPP Sprayliner is a two-component moisture insensitive, highly adhesive, chemical resistant, 100% solids, high strength and reinforced epoxy. Equal to “standard” CPP once cured, this version is packaged more conveniently for spray applicators seeking to utilize plural-component heated spray application. The material can be sprayed ultra-high build, between 1/16” – 1/4” (62.5 – 250 mils) per pass. Blended with reinforcing agents and various fibers, the Epoxytec CPP Sprayliner when cured creates reinforcement lining as a fiber-reinforced-polymer (FRP), with high strength and flexural properties for partially or fully deteriorated structures.

Features

  • 100% solids, no VOCs
  • Convenient 1:1 ratio
  • Indefinite recoat window
  • Excellent chemical resistance
  • Structural, with movement tolerance
  • No sag, ultra-high build, trowel-applied
  • Surface & moisture tolerant (cures underwater)
  • Ultra-high adhesion, self-priming

Product Applications

  • Concrete repair and protection
  • Chemical resistant liner
  • Ultra high moisture, wet solution
  • Industrial and treatment structures, tanks, pipes, stations, manholes, etc.
Typical Uses

CPP Sprayliner has been designed to line many aggressive, enclosed, immersive, and partially opened environments. CPP Sprayable performs in areas subject to chemical attack, and as a sealer preventing oxidation while holding back water migration and hydrostatic pressure.

Ideally suited as a protective coating/lining solution for:

  • Concrete repair and protection
  • Chemical resistant liner
  • Ultra high moisture, wet solution
  • Industrial and treatment structures, tanks, pipes, stations, manholes, etc. (ultra-high hydrogen sulfide [H2S] resistance [+800ppm] and resistant to sulfuric byproduct)
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. When logistics permit, prepare concrete in accordance with SSPC-SP 13/NACE No. 6. “Surface Preparation of Concrete.”

Steel: Before preparing steel, please inspect and remove oil, grease, or other contaminants – “Solvent Cleaning” (SSPC-SP1) may be required. Abrasive blasting (or other approved mechanical methods) must be used in order to achieve a clean surface with a minimum profile of 1.5 mils. To prevent flash rusting, consider the use of an Epoxytec recommended holding primer

Application Method

Epoxytec CPP Sprayliner is designed to be hand sprayed using a Kremlin Rexson / EXCEL PU3000+E System or similar. This is a fully heated, plural component system with recirculating and agitating heated hoppers up to 160F, materials flow through separate part A and part B continuously heated hoses. Mixing occurs in a static chamber prior to a single whip hose; and must have purging capability through the mixing chamber, the whip hose and spray gun. The system must be fixed ratio of 1:1 by volume with a minimum of 25 gallon preheating holding capacity for each part of material. Further detailed spraying equipment specifications can be obtained by select vendors.

Epoxytec limits the sale of Epoxytec CPP Sprayliner until all equipment and know-how is validated by one of Epoxytec’s certified equipment vendors and consultants. In addition, Epoxytec only recommends select, Epoxytec CPP Sprayliner certified consulting vendors/distributors to validate the equipment and know-how prior to fulfilling any production or sales order. For detailed spray equipment specifications, heating, pressure, power, hose specs, purging/cleaning requirements or designs- contact Epoxytec for a list of Epoxytec CPP Sprayliner certified equipment vendors/distributors.

Kit comes with A component and B component separately.

Purge and clean with Epoxytec Cut 5 solvent.

Film Thickness

CPP Sprayliner can be applied as a single coat or multi-coat system. It can sprayed to a minimum 100 mils up to a high build barrier liner at 350 mils DFT without sag per coat. For applications requiring thicker lining, multiple passes may be utilized.
