MPC-290 is a solvent-based, two-component, VOC compliant, aliphatic Poly aspartic 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-290 provides superior abrasion, chemical, and UV resistance with a crystal-clear glossy finish. Long pot life for easy workability with fast cure times Crystal clear, non-yellowing, and good gloss retention Excellent adhesion to a variety of substrates Excellent chemical and abrasion resistance Easy to mix 1:1 Ratio by volume Download Technical Sheet Perfect for UV-stable topcoats, protective residential flooring surfaces, industrial shop floors, maintenance facilities, marine protection for fiberglass, steel, concrete, or wood surfaces, aircraft hangars, offshore platforms, secondary containment, cooling towers, bridges, and also wastewater treatment applications 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). Poly aspartic chemistry was first introduced in the early 1990s making it a relatively new technology. The patents were issued to Bayer in Germany and Miles Corporation in the United States. Pure polyurea reacts extremely quickly making them almost unusable without plural component spray equipment. Poly aspartic technology utilizes a partially blocked amine to react more slowly with the isocyanates and thus produce a modified polyurea. The amine/diamine or even triamine functional co-reactant for aliphatic Poly isocyanate reacts with a maleate. Poly aspartic esters (PAE) as they are often call, initially found use in conventional solvent-borne two-component polyurethane coatings.
