Technical Data Sheet MPC-275
Product Description
MPC-275 is a solvent based, two component, VOC compliant, aliphatic polyaspartic polyurea coating system. It was specifically developed to be used a as UV stable topcoat finish where installation downtime is limited. It is recommended for areas where a thin clear coat is desired over colored coatings or vinyl flake broadcast systems. MPC-275 provides superior abrasion, chemical, and UV resistance with a crystal clear glossy finish.

Packaging and Recommended Thickness
MPC- 275 is offered in the following kit sizes:
- 2 gallon kit (3.78L resin (A) and 3.78L hardener (B))
- Bulk packaging also available upon request

Over vinyl flakes: 133-200 ft2/gallon @ 8 mils
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).
Mixing Instructions
Mix only the amount that you need at one time and pour the mixture within 10 minutes. Unused resin and hardener should be left in original containers. Mix exact amounts of both resin and hardener in separate mixing cups. Do not add more hardener than resin, as this will cause the finished coating to remain sticky.
Product Application
Apply MPC-275 using a rubber squeegee and roll to obtain a uniform coating (using a fine quality 10mm roller).
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 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.
