“Using Arkema’s unique and patented technology, CLEARSTRENGTH® XT powder is the exception to the rule when it comes to core/shell tougheners,” said Alexandre Vermogen, global marketing manager for Plastic Additives, Arkema. “The new CLEARSTRENGTH® XT 151 toughener was designed primarily for epoxy formulators to enhance the durability and performance of thermosetting resins while also providing excellent processability.
