Abstract
Disclosed are derivatives of isophorone diamine exhibiting a synergistic relationship with other commonly employed chain extenders offering enhanced efficacy with regard to slowing of the polyurea elastomer cure profile, and processes employing their use. According to the invention, extensions of the gel-free and tack-free times are more readily achieved at lower loading levels for these chain extender blends than are afforded through the sole use of the individual molecules.
