Ketjenflex® 2 is a toluene sulfonamide based reactive plasticizer used in Melamine molding compounds and a brightener in metal plating formulas. Ketjenflex® 2 is a basic starting material in the preparation of melamine formaldehyde molding compounds. Reacted into the resin backbone KETJENFLEX® 2 imparts long term impact resistance and toughness. Ketjenflex® 2 can also be used in other thermoset resins like epoxy and polyurethane based polymers resins.
