ViscoTec recently launched its new optimized dispenser series for small dispensing quantities. According to the company, both one- and two-component dispensers have been optimized for the application of very small quantities with maximum precision.

The one-component (3RD3) and two-component models (ViscoDUO-P 3/3 and ViscoDUO-P 4/3) reportedly offer precise dispensing results with an accuracy of ± 1%. Minimum quantities of 0.002 ml for the 3RD3 and 0.005 ml for the P 3/3 can be dispensed.

Various stator materials are available for the newly developed products to meet the requirements of different applications. ViscoTec reports that the dispensers are particularly effective in potting applications or for dot and bead dispensing in adhesive and sealing applications, making them suitable for the electronics industry, automotive, and similar applications.


Two-Component Static Mixing

The two-component ViscoDUO-P 3/3 and ViscoDUO-P 4/3 models provide the static mixing of two components of the same or different viscosity. Maximum flexibility is facilitated with various combinations of the ViscoDUO-P 4/4, 4/3, and 3/3 units.

A parallel arrangement of two dispensing units ensures a space-saving, compact design. Their modular construction enables a wide range of mixing ratios up to 10:1 due to the use of different dispenser sizes. The two-component dispensers are suited for two-component adhesive materials based on epoxy resin (EP), polyurethane (PU), silicone (Si), acrylate, and many others.
