Mixing epoxy without including air improves performance

Traditional hand mixing of two-part epoxies – especially in cases of extreme viscosity difference – can result in the inclusion of substantial quantities of air bubbles, as well as much mess and waste.

The resulting mix tends to be non-homogeneous and inconsistent/unreliable in performance. Now the Thinky ARE-250 from Intertronics can address these issues.

Tests with the Thinky ARE-250 using two-part epoxy structural paste adhesives showed that small exact quantities can be mixed reliably and cleanly in a fraction of the time taken by hand and with consistent optimal results every time, even compared with a hand mix plus secondary degassing process. Results included reduction in mixing time from 20 minutes to 20 seconds and complete elimination of observable air bubbles with a consequent 15% improvement in lap shear test strengths.
