摘要： Polyurethane prepolymers having non-linear short chain diols and/or soft diisocyanates incorporated into the backbone are used to provide cured polyurethane coatings having a high hard segment content and low haze. The polyurethane prepolymers can also be used to improve the dispersion of filler in cured polyurethane compositions having a high filler loading. Cured coatings prepared from the two-part polyurethane systems meet the requirements for aerospace applications.

摘要： Durable polyurea copolymer coatings can be applied to surfaces that come in contact with fluids, such as biological fluids, thereby passivating the surface. Polyurea copolymer coating compositions comprise a reaction product of (a) a diamine composition that includes a polyethylene glycol diamine, and optionally, a dipiperidyl alkane; and (b) a diisocyanate. Solutions containing polyurea copolymers, coated surfaces and methods are also described.

摘要： The present invention provides a polyaspartic composition comprising a reaction product of a polyamine and a Michael addition receptor reacted in the presence of a catalyst comprising a phenolic compound, with the proviso that the phenolic compound is not a phenol which is substituted with tert-butyl groups in both ortho positions to the oxygen. Suitable phenolic compounds include phenols, phenolic aldehydes, alkylphenols, benzenediols, cashew nut oil, and combinations thereof. Coatings, adhesives, sealants, composites, castings, and films comprising a polyurea composition may be made by reacting a polyisocyanate with the inventive polyaspartic composition. In particular, floor coatings made with the inventive polyaspartic composition have an elongated work time and a short walk-on time compared to current floor coatings.
