EXAMPLE - To a flask, hexahydrophthalic anhydride (304.6 g) and Terathane 250 (RTM: polytetramethylene etherglycol) (248.1 g) was added. The mixture was heated at 100 degrees C with stirring under nitrogen atmosphere for 155 minutes. The reaction mixture was cooled to 60 degrees C and then Epon 828 (RTM: bisphenol A epichlorohydrin resin) (1431.6 g) and triphenyl phosphine (15 g) were added. The reaction mixture was heated at 110 degrees C for 150 minutes. The mixture was cooled to room temperature. The resultant compound (I) had 99.89% solids, an acid value of 0.2, and an epoxy equivalent weight of 380.7. The resultant compound was the epoxy adduct of the first component of the two component structural adhesive material. An adhesive composition comprising first component containing (wt.%) Epon 828 (40.5), compound (I) (12), Wacker HDK H17 (RTM: hydrophobic fumed silica) (3.5), and Tint AYD ST8454 (RTM: ORG yellow tint base) (0.02); and a second component comprising (wt.%) Jeffamine D-230 (RTM: polyoxyalkylene amine) (12), triethylenetetramine (2.3), Accelerator 399 (RTM: mix of alkanolamine and piperazine derivative) (2.2), Microglass 9132 (RTM: silane chopped fiberglass) (8), Hakuenka CCR-S (RTM: precipitated calcium carbonate) (6), Wacker HDKH17 (2), and Tint AYDPC 9298 (RTM: phthalo blue pigment dispersion) (0.01), was prepared. The composition showed elongation of 3.7% and tensile strength of 68 MPa.
