Recommended uses SPUA-601 is a 100% solid, fast set, spray-applied, two component aromatic polyurea elastomer. The system consists of the A component, a quasi-prepolymer rich of free NCO, and the B component, a mixture of polyetheramines, amine extenders and other additives. The unique polyurea chemistry allows this material to be tolerant of moisture and lower temperatures during application. This means that high humidity and hidden moisture in concrete has minimal effect on the application of this product.

Surface must be properly prepared. Remove all oil, dust, grease, dirt, loose, and foreign materials to ensure adequate adhesion. Steel Surfaces must be a "near white metal" blast to SIS-Sa 2 1/2. with a 3 mil profile. Prime with SPUA-D100 Anticorrosive Primer prior to spraying. Steel surfaces shall be dry and clean, free from any dirt, grease, oil and other contamination before priming and spraying. Concrete Concrete surfaces prepared according to NACE standard RP0892-92. Allow substrate to dry thoroughly prior to priming (minimum substrate of new concrete cure is 28 day). Remove all from loose dust or other foreign matter and prime with primer SPUA-D400 Sealing Primer at 1~2 coats prior to spraying.
Surface dry (25 C) < 1 minute Hard film (25 C) < 10 minutes Recoat time minimum unlimited Maximum ≤3 hours Due to rapid cross-linking, recoating must be done as soon as the first coat is dry. If maximum recoat time is exceeded, abrade surface before recoating. Consult us for recommended recoat procedures.
Temperature: Air and surface: -20 C~40 C At lease 3 C above dew point Relative humidity: ≤90% Materials must be preheated to 21°C prior to use. Contact us for detailed application information.
Clean Up Instructions
Clean tools and equitment immediately after use with SPUA-PC Proportioner Cleaner or SPUA-GC Spray Gun Cleaner. Consult Plural Component Equipment Guide for specific information.
