Features

The Posi-Ratio® (PR) system offers the extreme variability (-Xv) needed for precise metering, mixing and dispensing of two component adhesives and sealants. The base purge minimises mixer consumption and material waste.

Innovative design and durability make this variable ratio system ideal for bonding, gasketing, metering, potting, sealing and thermal management applications. For highly abrasive, two component epoxies, silicones, acrylics, urethanes, polysulphides and thermal interface materials (TIMs), choose Elite construction.

  • The flexible shot size range meets the demands of small, medium and high flow dispense with +/- 1 percent shot repeatability.
  • The patented first-in-first-out (FIFO) fluid path eliminates dead zones, where material can accumulate.
  • A high wear resistant metering tube handles thermal interface material (TIM), other fillers, and different viscosities.
  • Servo motors deliver precise and repeatable dispense.
  • The twin control (TC) valve individually regulates on and off of A and B outlets.
  • Pressure transducers allow you to constantly monitor fluid pressure.
  • The base purge function conserves the amount of material used and keeps material from curing, so that mixers do not need to be replaced frequently.
