Covestro, formerly known as Bayer Material Science, is a manufacturer of high performance isocyanates and polyether polyols used to produce polyurethane and polyurea systems. While Covestro's  products are very good, we believe that TRiiSO can provide product  with equal or better performance properties that represent a better value overall.
