Fortegra 351 toughening technology improves toughness of epoxy systems for laminates, adhesives, composites, castings and coatings. Is said to increase reliability and durability under high mechanical stresses during drilling process, while also helping maintain thermomechanical and electrical properties. Is based on dispersed preformed particulate toughening technology, which complements existing proprietary block copolymer technology.
