  • Polyurethaneurea system
    Patent number: 8261798
    Abstract: A polyurethaneurea system that includes in some embodiments Parts A and B reaction components for a polyurethaneurea, wherein an exemplary embodiment provides a Part A that comprises between 55 and 75 wt. % of an oligomeric polyol, between 3 and 7 wt. % of an aromatic diamine chain extender, and between 0.1 and 1.5% of a reactivity catalyst; Part B includes between 1 and 15 wt. % of a short aromatic diisocyanate and between 5 and 35 wt. % of an aromatic diisocyanate prepolymer that is the reaction product of a short aromatic diisocyanate and a diol. The polyurethaneurea system may further comprise an elastomer-surface activator comprising a second short aromatic diisocyanate and a second aromatic diisocyanate prepolymer, wherein at least one of the second diisocyanates may be the same as at least one of the diisocyanates of Part B.
