A US study has proven the easy processing of automatic mixing systems:
“Use of the electronic technique made it easier to facilitate equal mixing ratios between base and catalyst, providing better quality of mix. The electronic mixing technique could reduce potential contamination and facilitate more reliable working and setting times for definitive impression as compared to the hand-mixing technique.“ Source: Nam, J., Raigrodski, A.J., Townsend, J., Lepe, X., Mancl, L.A.: Assessment of preference of mixing techniques and duration of mixing and tray loading for two viscosities of vinyl polysiloxane material.
