Wanhua Chemical recently introduced three new fast curing amine-functional resins for the polyaspartic, polyurea and polyurethane coatings markets. The chemical structure of these products provides unique reactivity with polyisocyanates. Wanamine PA-220, PA-420 and PA-520 are designed for use in high-performance, fast-cure, low VOC, low-odor coatings, both clear and pigmented.

Polyaspartic coatings based on Wanamine PA-220 can produce fast curing speeds of 1 to 2minutes, depending on ambient temperature and with a trimer-type isocyanate. Applications for polyaspartic coatings include use on concrete, metal and wood, with and without primer. Excellent intercoat adhesion also allows application on epoxies and polyurethanes.

Wanamine PA-420 produce curing speeds in the 15 minutes to 2-hour range whereas Wanamine PA-520 is the slowest reacting polyaspartic amine with cure speeds in the 15 minute to 2 hour or more range.
