- Features & Benefits
All‐in‐one‐shot, Structural Liner/Coating:
- The CPP Series when used as coating/liner, can resurface, rebuild, and protect all-in-one-shot as a sealed system preventing infiltration and exfiltration, and combating the effects of corrosion.
- Many times corrosion can deteriorate concrete and risk the integrity of the structure.
- In addition to the aforementioned, CPP performs exceptionally over the rebar and for repairs to areas of concern.
- It boasts impressive structural properties due to its blend or resin and reinforcing fibers; 16,000 psi compressive strength with high flexural strength.
Easy Mix, Simple Mobilization, Ease of Application:
- What this means to the applicator and Owner to have the CPP as a premeasured kit is that it is easy to mix as a no complicated mix ratio, meaning less room for human error, higher installation success.
- Kits are packaged in standard premeasured units requiring no complicated equipment to use (while other options are available, such as a 1:1 repair gel version and the sprayable version).
- Standard CPP may be simply applied by trowel.
Moisture and Wet Tolerant (Can Even Cure Underwater):
- Wet tolerant is actually an understatement because the CPP Series can adhere and cure underwater (used to repair seawalls underwater).
- This is a unique quality that is needed and used often in the water and wastewater industry to solve logistical challenges, such as working in "live" environments.
- Very few systems can withstand high levels of moisture without failing.
- The CPP Series performs well in humid environments (especially found in closed environment structures) such as closed tanks, pipes and underground structures.
- It's great to use, while some structures are in service, as it can cure without any effects exposed to splash or even overflow, as long as the flow is not aggressive.
Adhesion, Forgiveness and Surface Tolerance:
- This is where CPP shines.
- The CPP Series has been proven to be extremely surface friendly.
- Adhesion is one of the most important features of any coating in preventing corrosion for the long term.
- The CPP Series is self-priming and has unbelievable adhesive properties.
- The coating can often bridge the gap when unknown environmental control limitations occur; the coating is able to be applied and outperform better than typical surface-sensitive competitive products.
- CPP adheres to most surfaces, often outperforming even on questionable or imperfect surfaces to bridge unknowns; this is often accomplished with substrate breaking bond strength on concrete (greater than the cohesive strength of the concrete itself).
High Build, Durable & Resistant:
- What this means to the applicator is that they can apply a thick coating (up to 1/2" per pass) on the first time and eliminate multiple layering costing time and labor, which results in costing money.
- For the Owner, the liner results in a high build, a durable, and lasting shell-like solution to seal and protect.
- The CPP Series does not act like a typical coating; rather it can be better categorized as a permanent barrier shell or patch.
- It does not fail due to delamination like a thin or brittle coating could.
- It can take chemical attack, gaseous or microbial attack, hydrostatic pressure, rooting pressure, vibration, etc.
Easily Repairable:
- The CPP Series is a system that can be recoated, repaired, and touched up without complicated preparation simple cleaning and degreasing is all that is needed.
- It never loses its recoat window, nor fails catastrophically.
- This makes having a long-term maintenance program feasible with high life-cycle expectations, usually just requiring simple visual inspection and touch-up (often just with a brush) when needed.
- Doing this can extend the life expectancy for decades with minimal investment and uncomplicated application.
Applications & Uses
- Applications
- Typical Uses
- 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.
- Industrial and treatment structures, tanks, pipes, stations, manholes, invert sections, flow channels, etc.
- Including potable water (ultra-high hydrogen sulfide [H:S] resistance (+800ppm])
- Film Thickness
- 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) at 70°F thick without sag per coat.
- For potable water environments, check current UL listing for recommended maximum film build limitations.
- Theoretical Coverage
- CPPT is 100% solid and will not shrink.
- Therefore, the theoretical coverage properties between wet film thickness (WFT) and dry film thickness (DFT) are the same.
- Twenty-six (26) square feet (sq.ft.) per gallon (gal.) at 1/16 inch (62.5 mils) thick.
- One gallon of neat CPP yields 231 cu.in. of epoxy.
- Surface Preparation
- 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 (1CRI CSP-5 min).
- 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 4 mils.
- To prevent flash rusting, recommended holding primer. consider the use of an Epoxytec recommended holding primer.
- Mixing
- Add Part B to Part A and mix for a minimum of 4 minutes with a low speed drill until a homogenous blend (uniformed color, with no streaks) is achieved.
- Mix with movement, getting the pail’s edges, walls, and bottom
- Do not add sand or aggregate; a special gelling agent and filler is incorporated to allow up to 0.5 inches at 70°F of fill and hang on vertical or overhead surfaces without sagging, and to achieve performance properties.
- Application Method
- 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; afterward, 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.
- For potable water environments, check current UL listing for recommended maximum film build limitations.
- Limitations
- Avoid surface and/or ambient air temperatures above 120°F.
- If material is applied in excessive mass and/or influenced by high heat (surface and/or air) foaming could occur and adversely affect cured properties.
- Cooler temperatures could slow down the cure schedule, and in extreme cases, adversely affect reaction and cured properties.
- To optimize crosslinking in cooler environments, apply materials to substrate/surfaces above 45°F, and with air/ambient temperatures above 55°F.
- Take precautions to ensure temperatures are stable or trending higher as material cures.
- Should it be predicted that temperatures will drop lower during its cure time, or if application thicknesses are less than 1/4” (250 mils), consult with Epoxytec, as methods and controls to keep material, surface and air temperatures warmer during the cure may be prescribed.
- Thinning
Do not thin Epoxytec CPP.
