H.B. Fuller EH9672

H.B. Fuller EH9672 is a fast-setting, reactive hot melt adhesive and sealant. It is a 100% solid, one-component material with a secondary moisture cure system. This material is applied warm and sets immediately, allowing handling without the need for heat curing. It has optimum adhesion to a wide range of substrates, including aluminum, stainless steel, and especially common engineered plastics such as polycarbonate, ABS, and nylon. H.B. Fuller EH9672 may also be easily reworked by heating the bonded assembly to 80 - 90°C, allowing damage-free disassembly. The cured product can then be easily removed, leaving minimal residue.

Identification & Functionality

Features & Benefits

Ready-to-Use Product Features
Features and Benefits
  • Good adhesion to a wide range of substrates without the need for primers
  • Easy rework and removability at temperatures exceeding 75°C, with minimal residue.
  • Dispenses like a one-part hot melt adhesive, but reacts when exposed to moisture to form a strong cross-linked network like a tough urethane polymer.
  • Greater than 50% of full cure strength achieved within 4 hours of dispensing, depending on ambient humidity and temperature.
  • Low melt temperature (110-125°C) before cure allows application and bonding to a wider range of heat sensitive materials.
  • Designed for use with automated heating dispensing without stringing.
  • Open time up to 15 minutes, allowing for extended assembly time.

Applications & Uses

Cure Method
Typical Applications
  • EH9672 can be dispensed using automatic heating, dispensing or dipping systems at temperatures of 115°C +/- 10°C.
  • Green adhesion will be achieved as soon as the adhesive bond has cooled.
  • To clean spilled adhesive, allow the adhesive to cool to room temperature and remove heavy deposits. Any uncured residual adhesive can be scraped off using a blade. After scraping, wipe clean with a common polyurethane solvent (toluene, MEK). Clean up the adhesive residue before it cures.
  • If the dispense equipment is to be shut down for extended periods of time, we recommend purging the system with HB Fuller NP2038L 050. Partially used containers of EH9672 should be purged with a dry inert gas and resealed between uses.

Technical Details & Test Data


The chemical reaction that results in cross-linking begins in the presence of low levels of atmospheric moisture. The rate of cross-linking will vary depending on temperature, humidity, and thickness.
