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.
