Directions for Use

For optimum results, parts should be clean and free from any oils, contamination or loose surfaces (rust). If parts do not mate flush or closely together, you will need to use a product that has higher viscosity to compensate for the gap. Any excess adhesive can be removed with debonder.

Technical Details & Test Data

Factors Affecting Cure Speed
  • Gap : Thin bond lines result in faster cure speed. The larger bond gaps will lengthen cure speed.
  • Humidity : Cyanoacrylates cure as a function of water content. Higher humidity will cure products faster. Fixture times are normally measured at 50% relative humidity (RH).

Storage & Handling

Storage Information

Store in unopened containers, out of the direct sunlight, in a dry location, at room temperature (75°F). Refrigeration can extend shelf life.
