Solutions for Applying Bondway 8868 Thermally Conductive Adhesive

Dispensing solutions for Bondway 8868 thermally conductive adhesive polyurethane must withstand the highly filled and abrasive material. That is why Graco provides a complete system with Elite construction to meet Bondway 8868 application requirements*.

  • Supply Pumps: Check-Mate supply pumps provide advanced durability and reliability for transferring material.
  • Meter Mix and Dispense System:  Graco’s Hydraulic Fixed Ratio (HFR) system delivers unmatched durability, performance for two-component materials.
  • Dispense Valves: MD2 valves with Elite construction have been proven to dispense nearly 3,000 litres (more than 2 million cycles) of TIM blend with no failures detected.**

* Additional Elite construction system configurations are available depending on application and performance requirements.

 **Results may vary. Variables affecting component life include, but are not limited to, material chemistry/fillers, flow rate, cycle rate, maintenance diligence and system pressure.
 

Elite Construction Withstands Bondway 8868

Graco tested how Check-Mate supply pumps and HFR system with Elite construction performed while mixing, metering and dispensing Bondway 8868 thermally conductive adhesive polyurethane.

System Configuration for Two-Component Bondway Dispense Testing includes HFR with Elite Construction and 100cc Supply Pumps with Elite Construction.

The equipment with Elite construction dispensed at least 200,000 litres (50,000 gallons) before any wear on pump pistons and cylinders was noticed.
