Technical Data Sheet MPC-155
Product Description
MPC-155 is a 2-component, very fast curing 100% solids, self-leveling and high-build epoxy floor coating. It is designed to be used as a protective floor coating on concrete, over an existing epoxy coating or to create metallic/decorative flooring systems. It can also be used as the binder component for resurfacing or patching surfaces exposed to severe and aggressive industrial environments. MPC-155 is a specifically formulated cycloaliphatic coating that reduces water spotting and amine blushing while providing excellent adhesion, abrasion, impact and chemical resistance.
This seamless coating from Master Protective Coatings is offered in a wide number of colors and can be top coated with a variety of MPC products to achieve different gloss finishes and textures. This coating contains no solvent, is complaint with the CFIA regulations for indirect food contact and meets the VOC regulations limit of under 100 g/L for architectural floor coatings.

Surface Preparation
Remove dust, dirt, grease, oil and all other contaminants with proper cleaner/degreaser. Prepare the surface mechanically as per ICRI-CSP2 profile by diamond grinding to ensure removal of laitance, curing agents and sealers. The compressive strength of a newly poured concrete substrate must be at least 25 MPA (3635 psi) after 28 days cure and at least 1.5 MPA (218 psi) tensile strength. Be careful with condensation (within 10 degrees of the dew point). All cracks, holes and irregularities must be repaired with our epoxy crack filler (MPC-125) prior to applying the coating.
Mixing Instructions
The products must be conditioned between for 18°C (65°F) and 30°C (86°F) prior to application.
Clear/Colored version: Pre-mix each component separately for 2-3 minutes each. Open container with 2 parts of component A in it, then add the 1 part of component B to it (mixing ratio 2:1). Mix the components for a maximum of 30 seconds using a low-speed drill (300-450 rpm) to reduce air entrapment and to obtain a homogeneous mixture.
Metallic version: Pre-mix each component separately for 2-3 minutes each. Open container with 2 parts of component A in it, then add 6 ounces of metallic pigment and mix approximately 1 minute using a low-speed drill (150-200 rpm). Let the colored resin sit for at least 30 minutes to ensure proper pigment wetting. Then add 1 part of component B (mixing ratio 2:1). Mix the components for maximum of 30 seconds using a low-speed drill (300-450 rpm) to reduce air entrapment and to obtain a homogeneous mixture.
Product Application
- Apply 1st coat of MPC-155 using a rubber squeegee and roll to obtain a uniform coating (using a fine quality 10mm roller).
- Apply 2nd coat of MPC-155 as a finish coat, using a rubber squeegee and roll with a fine quality 10mm roller to obtain a uniform finish.
(For metallic or decorative finishes please inquire on application procedures)
Clean equipment with xylene. Once the product has hardened, it may only be removed mechanically.
Product Restrictions
- Not recommended for application at temperatures below 10°C / 50°F or above 30°C / 86°F.
- Ambient humidity of the surroundings should not exceed 85% during application and during curing process.
- Substrate must be clean, sound and dry.
- Substrate temperature must be 3°C (5.5°F) above measured dew point.
- Humidity content of substrate must be < 4% at time of application.
- Do not apply on porous surfaces where a transfer of humidity may occur during the application.
- Applying this product on a substrate without a moisture barrier may risk delamination due to hydrostatic pressure.
- Freshly applied product must be protected against moisture, condensation and water for at least 48 hours.
- Surface discoloration of product may occur when exposed to UV rays.
- Exposure during the curing stage of the coating to the by-products of propane combustion may cause discoloration (amine blushing)
