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: Concrete must be sealed with a high density mortar, Epoxytec Mortartec Silicate, and primed prior to starting. An ICRI profile of CSP 5 of higher is required of the mortar. Full cure of the mortar is required. Prepare concrete in accordance with SSPC-SP 13/NACENo. 6. “Surface Preparation of Concrete.” Priming, with Epoxytec B1 Primecoatis required (2 coats, and fully cured prior to commencing) Important! Although the technical details and recommendations contained in this data sheet correspond to the best of our knowledge and experience, all the above information must, in every case be taken as merely indicative and subject to confirmation after long-term practical applications; for this reason, anyone who intends to use the product must ensure beforehand that it is suitable for the envisaged application. In every case, the user alone is fully responsible for any consequences deriving for the use of the product. The sole liability of Epoxytec for any claims out of the manufacturer’s use of sale of its products shall be for the buyer’s purchase price.  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 4mils. Stripe coat all edges and peaks with an Epoxytec recommended primer. Prime with Epoxytec A1 Primecoat. 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 B1 Primecoat).

Application Method

Epoxytec MPC Flexclad™ 65 must be applied by plural component airless/air-assisted airless spray equipment  OR  the Epoxytec EZ-Spray System (disposable cartridge spraying).If using compressed air for spraying, use an air filter and dryer. For optimum properties, maintain product in heated storage between 70ºF and 80ºF. Dew and rain on MPC Flexclad™ 65 while uncured may impair its cure and adhesion of subsequent coats.If you are going to be spraying small, intricately shaped parts, or applying a thin layer of elastomer, the recommendation is to use a low-pressure cartridge system equipped with a small or static mixer and an air-assisted spray tip, such as the Epoxytec EZ-Spray System. Dispensing/spraying via a pneumatic gun. Air pressure between 60-90 psi is recommended.If spraying large surfaces of thick layers of elastomer, you must select a high-pressure metering machine and spray gun, or a high-output, low pressure metering machine that can spray a a rate of 7-10 lbs. per minute, and spray gun equipped with either a dynamic or static tip. When applying with high pressure airless equipment (2500-3000 psi), components should be heated to (160°F-170°F) to assure good mixing. A number of types and styles of spray gun/mixers can be successfully, including high pressure impingement guns. The selection of a spray tip is dependent on the nature and size of the object to be sprayed. The tips will have an effective fan width of 25 or 30 degrees, and an equivalent orifice size of between .026 inch to .053 inch. A general rule wouldbe the smaller the surface to be sprayed the smaller the orifice. The use of the small tip size reduces the total throughput of elastomer. For example the use of a .026 inch orifice would result in an output of about 3 pounds per minute. The output using the .053 inch orifice will be circa 10 lbs/min.

Film Thickness

MPC Flexclad™ 65 can be a single coat or multiple coat system. MPC Flexclad™ 65 can be applied onto a surface at 60 mils (minimum) to 350 mils (maximum) per coat. For a total coating thickness exceeding 350 mils, multiple coats are necessary. Note: MPC Flexclad™ 65 has a short recoat window. To apply multiple coats, prepare accordingly.

Storage & Handling
Shelf life: 6 months, sealed. Store in a dry area away from direct sunlight. The material should be conditioned to between 75º F and 90º F before use.

MPC Flexclad 65

Epoxytec MPC Flexclad™ 65 is an ultra-fast curing, ultra-high build elastomeric polyurethane, rubber-like barrier liner/coating to seal and protect against corrosion in high impact, abrasion, and/ore high chemical or temperature environments.

MPC Flexclad™ 65 represents the latest in polyurethane advancements.  The aromatic liner is 100% solid, exhibits 400% tensile elongation, and begins to cure within 30 seconds upon spraying.  Terrific for environments requiring ultra-high build, flexible lining to combat chemicals, corrosion, and other industrial containment.  Being urethane-based, the material has excellent abrasion resistance and flexural cross-link sustainability.  Easy to apply with a plural component, 1:1 ratio by volume, or the Epoxytec EZ-Spray System (disposable cartridge system).
