A new line of low-viscosity epoxy tougheners is designed for amine-cured, DICY, anhydride-, and phenolic-cured systems where greater mechanical performance is needed in addition to adhesion and corrosion/chemical resistance. The Fortegra line from Dow Epoxy Performance Resin Group, Midland, Mich., is based on a special “self-assembling” block copolymer that does not cause big changes in viscosity, cure speed, or chemical resistance. Dow claims these tougheners are effective at levels as low as 3% to 10% percent by volume, less than for similarly priced alternative products. The toughener is available on its own or in blends with epoxy resins. (800) 441-4369 * www.dow.com
