Abstract
A thermo-set resin composition comprising a Quebracho wood tannin extract, a furfuryl alcohol, a neoprene compound, a dimethicone, polyethylene glycol, abrasive particles, and a glycerol phosphate acidic ester and/or graphite. Further, a method of preparing the thermo-set resin composition including mixing Quebracho wood tannin extract with a furfuryl alcohol to form a primary mixture, adding additives and abrasive particles to the primary mixture, and reacting the primary mixture by adding a catalyst. The thermo-set resin composition is molded into a shape under heat and pressure to a Brinell hardness 8.5 daN/mm2 and 48 daN/mm2 and can be incorporated into a friction pad of a brake pad.
