PERMABOND 825

Main features

  • Thermal-Aging Bond Strength Retention
  • Fast 5-20 Second Fixture
  • Low-Viscosity 0.15 mm Gap Bonding

Product Description

PERMABOND 825 is a low-viscosity modified ethyl cyanoacrylate adhesive combining rapid room-temperature cure with high-temperature and thermal-aging performance. Typical viscosity is 100 to 150 mPa s at 25 deg C with a maximum gap fill of 0.15 mm. Fixture strength develops in about 10 to 20 seconds on steel and 5 to 10 seconds on NBR, while full strength develops in 24 hours. The cured adhesive provides measured shear strength on mild steel, stainless steel, aluminum, and engineering plastics, and its bond-strength retention has been tested during thermal aging at 180 deg C.

Key features

  • Thermal-Aging Bond Strength Retention: Bond-strength retention has been tested during thermal aging at 180 deg C.
  • Fast Rubber and Metal Fixture: Fixture times range from 5 to 20 seconds across NBR, steel, and other specified substrates.
  • 0.15 mm Gap Capability: Typical viscosity of 100 to 150 mPa s supports a maximum gap of 0.15 mm.

Applications

Bonding rubber, metals, and plastics where high-temperature and thermal-aging capability is required.

Physical Properties
Viscosity
Viscosity is a measurement of a fluid’s resistance to flow. Viscosity is commonly measured in centiPoise (cP). One cP is defined as the viscosity of water and all other viscosities are derived from this base. MPa is another common unit with a 1:1 conversion to cP. A product like honey would have a much higher viscosity -around 10,000 cPs- compared to water. As a result, honey would flow much slower out of a tipped glass than water would. The viscosity of a material can be decreased with an increase in temperature in order to better suit an application
