VISCOTEC: Two-Component Adhesive Dispensing System
The eco-DUOMIX has been developed for difficult-to-mix two-component materials for which purely static mixing was previously not sufficient.
Preeflow, a ViscoTec brand, has launched the compact eco-DUOMIX, a dispensing solution that can mix and dispense silicones, epoxy resins, polyurethanes, polyester resins, and acrylates. The company reports that only a few mixing and dispensing systems can currently be used to mix and apply all existing adhesives. The biggest challenge is components that are difficult to mix, since they usually have to undergo a longer mixing process in order to optimally bond. To fill this industrial gap, the eco-DUOMIX has been developed for difficult-to-mix two-component materials for which purely static mixing was previously not sufficient.
Instead of a mixing spiral, the eco-DUOMIX is equipped with a mixing capsule optimized for dead space, which can be used for dynamic mixing. The company reports that materials with the same and/or different viscosities were developed and evaluated. Mixing ratios ranging from 1:1 to 10:1 are technically possible. The eco-DUOMIX is designed for speeds up to 2,000 rpm. Compared to the classic mixing spiral of other dispensing systems, the material consumption in the motor-driven mixing capsule is significantly lower, which has a positive effect on the overall cost, especially when using expensive materials.
