Product Benefits

Good dispersion

Clearstrength® E980 toughening agent provides improved dispersion capability, allowing lower mixing time than similar general purpose MBS core shell powder.

Enhanced mechanical properties

Clearstrength® E980 provides improved performance to various thermosetting resins, like ductility, room temperature and low temperature lap shear strength, impact strength, crack propagation resistance, and thermal shock resistance. The use of Clearstrength® E980 does not decrease the glass transition temperature of the final systems.
