Abstract
Resorcinol resin-blocked isocyanate compositions are derived from the reaction between a resorcinol resin and at least two different isocyanate compounds. The resorcinol resin-blocked isocyanate compositions may have two or more unblocking temperatures and/or melting characteristics that may provide some unique properties, such as improved adhesion of reinforcing materials to rubber compounds. The resorcinol resin-blocked isocyanate compositions can be used in fabric dipping formulations and/or rubber compositions with improved properties.
