How does CSR toughen resins?How does CSR toughen resins?
• Core polymer cavitates on impact dissipating energy .
• Small, evenly dispersed particles act as a crack terminator.

What is Kane Ace MX:What is Kane Ace MX:
Kane Ace MX are concentrates comprised typically of 25% by weight of CSR dispersed in various thermosetting resins. The liquids are easily poured after heating and the individual CSR domains remain uniformly dispersed during storage and formulating.
