Dispensing CoolTherm UR-2000

Parker LORD · 2K gap filler / thermal adhesive · 2 W/m·K

CoolTherm UR-2000 is an urethane 2K gap filler / thermal adhesive from Parker LORD, rated 2 W/m·K. Typical uses: Electronics thermal management; bonding powder/e-coated aluminum and PET film (EV battery). Short answer: we dispense it with a PDP two-component progressive cavity metering pump with a static mixer.

How we dispense it

For a two-component thermally conductive adhesive we start with a PDP two-component progressive cavity metering pump and a disposable static mixer, fed from dual cartridges for lab and low volume, or from pails with a follower-plate pail pump for production. Pump size depends on your shot or bead size and cycle time.

  • Abrasion: the ceramic filler that carries the heat wears pumps out. We use tungsten carbide rotors and wear-resistant stators and run the pump slowly, at 8 to 12 rpm, for long wear life.
  • Ratio: each side is metered by its own progressive cavity pump to within ±1%. Check ratio by weighing a shot from each side every week, because filled materials vary from batch to batch.
  • Mixing: a disposable static mixer does the mixing. Purge or change it before the material's working life runs out.

Frequently asked questions

What pump should I use to dispense CoolTherm UR-2000?

For a two-component thermally conductive adhesive we start with a PDP two-component progressive cavity metering pump and a disposable static mixer, fed from dual cartridges for lab and low volume, or from pails with a follower-plate pail pump for production. Pump size depends on your shot or bead size and cycle time; send us those and we will size it.

Can CoolTherm UR-2000 be fed from pails instead of cartridges?

Parker LORD lists these packages: 5 gal pails. Cartridges suit lab and low volume. Above that, a follower-plate pail pump feeds the metering pump directly, which cuts container changes and waste.

How do you keep CoolTherm UR-2000 on ratio?

Each side is metered by its own progressive cavity pump, held to within ±1% per side. We recommend a weekly check: weigh a shot from each side and adjust, because filled materials vary from batch to batch.

Will CoolTherm UR-2000 wear out the pump?

Thermally conductive fillers are abrasive. With tungsten carbide rotors, wear-resistant stators and pump speeds of 8 to 12 rpm, stators typically last 6 to 12 months and rotors up to 24 months, and a pump rebuild takes under an hour.
