Adhesive Dispensing with METER MIX® Technology

PAR 20 & PAR 20C/20CE

Adhesive Dispensing

The PAR 20 series were specifically developed to process a wide range of high-viscosity material systems. Because of this the machines are optimally suited for adhesive dispensing as well as for metering and mixing of resins. Insulated and structural glazing applications can be stably managed and very accurately controlled. The METER MIX® PAR 20, 20C and 20CE machines incorporate reliable, proven technology in order to meter precise doses, or accurate beads of mixed product within a wide range of applications. The PAR 20 machine incorporates a follower seal plate for the major component and a gravity feed reservoir for the minor component, enabling the machine to process a mix of high-viscosity and low-viscosity resins, sealants and adhesives. The PAR 20C/20CE machines incorporate twin follower seal plates which allows both materials to be dispensed directly from the supplier’s containers. All machines of the PAR 20 series have the latest METER MIX® ILD (in-line drive mechanism) for accurate and consistent processing of materials with high mix ratios or vastly differing viscosities.
