Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
What is claimed is: 1. A polyurethaneurea system for bonding to a cross-linked rubber surface, wherein reaction components react to form polyurethaneurea, the reaction components comprising: part A, wherein part A is a mixture comprising: between about 55 and about 75 wt. % of an oligomeric polyol having an average molecular weight greater than about 1000; between about 3 and 7 wt % of an aromatic diamine chain extender; and between about 0.1 and about 1.5 wt. % of a reactivi…
