Abstract: PROBLEM TO BE SOLVED: To obtain an improved polyurethane compound usable as an embedding resin for a fan outlet guide vane assembly of a commercial gas turbine engine. SOLUTION: A polyurethane compound suitable for this invention is obtained by mixing a polyurethane prepolymer preparation with an aromatic amine curing agent in the ratio of about 0.9: about 1 to 1:1, preferably about 0.95:1 to about 1:1. The polyurethane prepolymer preparation related to this invention comprises a blend mixture obtained by blending different polyethers composed of diphenylmethane diisocyanate (MDI) as a base and the amine curing agent is a blended mixture of an oligomeric diamine and an aromatic diamine containing a catalytic component. These blend mixtures are both liquid at a room temperature.
