Pflaumer Brothers has launched two amine-functional resins for polyurea polyaspartic coatings used on concrete, metal, wood and other substrates. The two polyaspartic amines, Teraspartic 277 and Teraspartic 292, can be used individually or in combination with each other, or together with other amine functional resins or hydroxy-functional acrylic resins to achieve special performance attributes. The company said that Teraspartic 277 and Teraspartic 292 are stearically hindered aliphatic amines that react with polyisocyanates to form high-gloss, weather-resistant coatings with good film build and rapid cure rates. Polyaspartic coatings are used in high-performance applications requiring fast cure, low VOC and low odor. These coatings exhibit a combination of flexibility and impact resistance, ideal for use on concrete floors. They can be formulated with no VOCs, no odor and with a tack-free time of as little as 45 minutes.
Polyaspartic coatings dry efficiently at room temperature, a distinct advantage for the applicator. In addition, the applicator can apply polyaspartic coatings as thick films in one coat rather than two or more, again with the added productivity of fast-cure. These qualities allow for use in direct-to-metal application in paint shops as well as OEM, such as for the manufacture of wind energy turbines.
