CPP Sprayliner 61

Product Description

Epoxytec CPP Sprayliner 61 is a two-component, 100% solids, high build, spray-applied, structural grade epoxy system. Formulated specifically for use in potable, drinking water environments (certified ANSI/NSF-61), and utilizes a blended cycloaliphatic curing system for increase chemical resistance and UV tolerance.  Similar to “standard” CPP once cured, this version is packaged more conveniently for applicators seeking to spray with heated plural-component equipment. The material can be sprayed ultra-high build, up to 1/4” (250 mils) per pass. Blended with reinforcing agents and various fibers, the Epoxytec CPP Sprayliner 61 when cured creates reinforcement lining as a fiber-reinforced-polymer (FRP), with high strength and flexural properties for partially or fully deteriorated structures

Features

  • ANSI/NSF-61 certified
  • 100% solids, no VOCs
  • Convenient 1:1 (v) ratio
  • Indefinite recoat window
  • Excellent chemical resistance
  • Structural, with movement tolerance
  • No sag, ultra-high build

Product Applications

CPP Sprayliner 61 has been designed to line drinking water storage tanks, water pipelines, and other structures in contact with potable water, including water treatment processes. CPP Sprayliner 61 performs in areas subject to chemical attack, and as a sealer preventing oxidation while holding back water migration, inflow/infiltration (I&I), and hydrostatic pressure. Ideally suited as a protective coating/lining solution for:

  • Concrete repair and protection
  • Chemical resistant liner
  • Structural lining
  • Ultra high moisture, wet solution
  • Potable, drinking water storage and treatment lining

Surface Prep

The success of any coating application is directly proportional to the extensiveness of the surface preparation and the care into the application. Surface must be clean and sound. Remove all dust, contaminants, grease, curing compounds, rust, impregnation, waxes, foreign particles, and weak or disintegrated materials from the surface, and utilize advised methods to achieve a clean and profiled surface.

Concrete: Prepare the concrete by abrasive blasting, high pressure water cleaning or jetting, and/or other approved methods to achieve clean, sound, and profiled concrete (min. ICRI CSP-3) in accordance with SSPC-SP 13 / NACE No. 6. “Surface Preparation of Concrete.” NOTE: Epoxytec CPP™ Sprayliner™ 61 can be applied direct to concrete (DTC), self-priming. However, should an abnormal or conditional situation exist (ie- outgassing, MVT, etc), primers and/or resurfacers (although optional) may assist, and may be recommended.

Steel:  Inspect and remove oil, grease, chlorides or other contaminants – “Solvent Cleaning” (SSPC-SP1) may be required.  Abrasive blasting (or other approved mechanical methods) SSPC-SP10 / NACE 2, “Near-White Blast Cleaning,” must be administered in order to achieve a clean surface with a minimum profile of 100 microns (4 mils); remove dust and debris by high compressive air or solvent cleaning (SSPC-SP1) may be required again. Before preparing or applying on steel, verify that the temperature of the surface is at least 3 degrees C (5 degrees F) from the dew point temperature to preclude condensation. NOTE: Epoxytec CPP™ Sprayliner™ 61 can be applied direct to metal (DTM), self-priming. However, should an abnormal or conditional situation exist or if a “holding” primer is needed to prevent flash rusting, consider the use of an Epoxytec recommended primer.

NOTE: Methods outlined herein, are a min. basis of design of generalized guidance. Various detailed CSI-formatted project design specs are available for download at epoxytec.com, and/or consult with Epoxytec for other specific design considerations.

Application Method

Epoxytec CPP Sprayliner 61 is designed to be sprayed utilizing specialized equipment, specified, proven and sold by approved equipment vendors of Epoxytec. Requires fully heated, plural component system with recirculating and agitating heated hoppers up to 150F, with 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. Purge and clean with Epoxytec Cut 5 solvent. 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. NOTE: Epoxytec limits the sale of Epoxytec CPP Sprayliner 61 until all equipment and know-how is validated by one of Epoxytec’s certified equipment vendors and consultants. In addition, Epoxytec only recommends certain approved vendors 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 61 certified equipment vendors/distributors.

Film Thickness

CPP Sprayliner 61 can be applied as a single coat or multi-coat system. For mild conditions, CPP Sprayliner 61 can be applied at a minimum of 1/16” (~60 mils). For aggressive conditions, CPP Sprayliner 61 is recommended at a minimum 100 mils.  Maximum build-up per coat is 1/4” (250 mils) without sag per coat, depending on temperature. For applications requiring thicker lining, multiple passes may be utilized.

Note: For fully deteriorated structures, where a fully structural design thickness is required, various structural design criteria will need to be calculated for the proper thickness design recommendations.
