H.B. Fuller SI500

H.B. Fuller SI500 is an instant adhesive. It is designed to provide rapid bonding with a very fast curing time. This allows for quick assembly and efficient production processes, saving time and increasing productivity. SI500 has a medium-to-high viscosity, which means it has a thicker consistency. It is commonly employed in industries such as manufacturing, construction, automotive, and electronics where fast and reliable bonding is required.

Application Guidelines

  • For optimum results, parts should be clean and free from any contamination on the bonding surface.
  • If parts do not mate flush together, use a higher viscosity product to compensate for the gap.
  • Factors Affecting Cure Speed
  • Gap: Thin bond lines result in faster cure speed. Larger gaps will lengthen cure speed.
  • Humidity: Cure and fixture times can be influenced by the humidity conditions at the time of assembly. The higher the relative humidity (RH), the faster cure and fixture times will be.
  • Fixture time data based on our testing is conducted at 50% relative humidity.
