CPP
Product Description
Epoxytec CPP is a two-component moisture insensitive, highly adhesive, chemical resistant, 100% solids, high strength epoxy paste with superior adhesion. It is truly versatile and can be used as an adhesive, patching filler, or even as a high-build, stand-alone protective liner. The material can be applied a thin as a skim-coat and up to 1/2” per pass (vertical/overhead). Blended with reinforcing agents and various fibers, the Epoxytec CPP when cured creates reinforcement as a fiber-reinforced-polymer (FRP), with high flexural properties. Contains no solvents (no VOCs). CPP bonds to concrete, steel, wood, brick, some plastics and most construction materials.

Features
Product Applications
CPP has been proven in many aggressive, closed, immersive, and partially opened environments. 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, repair/filling epoxy as:
- Adhesive, segmental and anchoring epoxy
- Patching filler
- Concrete repair and protection
- Chemical resistant liner
- Ultra high moisture, wet solution
- Industrial and treatment structures, tanks, pipes, stations, manholes, invert sections, flow channels, etc. Including potable water. (ultra-high hydrogen sulfide [H2S] resistance [+800ppm] and resistant to sulfuric byproduct)
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 2 mils. To prevent flash rusting, consider the use of an Epoxytec recommended holding primer.
CPP must be applied by trowel, spatula or other hand applied method. To control the thickness Epoxytec recommends utilizing a notch trowel via two different means:
- Option #1 – use a notch trowel first and let it cure; afterwards, return to fill the notches with a straight-edge trowel.
- Option #2 – use a notch trowel, then flatten the application to achieve uniformed thickness.
Kits are premeasured. Mix full kit in its entirety. As an Adhesive: Apply to both bonding surfaces with spatula (putty-knife) or trowel. Join material. If necessary, clamp until cured. Strike off excess material. As an Anchor/Dowel: Vertical and overhead. Partially fill drill hole with CPP; It is permissible for the hole to be damp (remove excess water), however, the object must be dry. Work bolt in and out to compact the paste. Secure with templates. With object in position fill in remaining void. As a Coat / Patch / Fill: Vertical and horizontal surfaces. Apply to area with trowel or spatula. Work in at maximum layer of 0.5 inches per coat. Minimum application thickness = N/A. For potable water settings, apply between 30 -120 mils DFT.
CPP can be applied as a single coat or multi-coat system. It can be feather-edged from a low mil thickness (almost transparent) to a high build barrier liner of 0.5” (inches) @ 70F thick without sag per coat. For potable water settings, apply between 30 -120 mils DFT. For thicker passes, consult Epoxytec for various options.
| Storage & Handling | Shelf life: 18 months, sealed. Storage: Store in a dry area away from direct sunlight. The material should be conditioned to between 70º F and 85º F before use. |

CPP
Epoxytec’s CPP is a 100% solid epoxy, designed to be applied by trowel. The CPP system is formulated to provide a structural liner (with ultra-high flexural strength and properties), coating, or structural epoxy for repair, patching and rehabilitation of physical infrastructure and protection against corrosion.
The CPP technology is unique and proprietary, allowing for a polymer with outperforming performance in protection, adhesion and tolerance. CPP is formulated “green,” environmentally friendly, 100% solid (no VOCs, no solvent). The CPP system is easy-to-apply trowel. CPP is able to be applied feather-edge thin to ultra-high build. For long-term maintainability, the CPP system it ties back into itself indefinitely with no need for re-blasting or abrasion.
