Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
72 words
The reaction product of: (a) A difunctional epoxy compound having an average molecular weight of from about 342 to about 2,000; and, (b) A primary mono amine having from about 8 to 18 carbon atoms such that the combined molecular weight of (a) and (b) is from about 830 to about 5,600 in a mole ratio of the epoxy compound to the primary amine of from about 1.8:3 to about 2.4:3 respectively.
Claim 2
Dependent Claim
