Clear v4 resin compatibility issues

I am seeing some issues of clear v4 resin when used with Acetonitrile. It changes the mechanical properties of the printed structure and the structure gets fractured after exerting a small amount of force. I have tested this by taking two identical printed sample, one was immersed in ACN for 2 days and the other one was kept in open air. After 2 days, the one with ACN went through ductile failure when small amount of force was applied, while the other one seemed completely fine. Has anyone faced this issue? Any suggestion on the compatibility of clear resin?
