LORD 506

Main features

  • 4 to 6-Minute Working Window
  • Flexible Cured Adhesive
  • Environmental Resistance Acrylic Bonding

Product Description

LORD® 506 Acrylic Adhesive is a fast-curing structural acrylic adhesive designed for use with LORD® Accelerator 17 or 19. The mixed system forms a semi-flexible bond to a wide range of thermoplastics, thermoset plastics and prepared metals while accommodating shock and sudden stress loading. It cures rapidly at room temperature and provides documented performance from -40°F to 300°F (-40°C to 149°C).

Key Features

  • Broad substrate adhesion to ABS, acrylic, polycarbonate, FRP, prepared metals, urethane, phenolic, polysulfone and vinyl.
  • Rapid room-temperature cure with a 4–6 minute working time and handling strength in 8–12 minutes at 75°F (24°C).
  • Semi-flexible cured system accommodates shock and sudden stress loading.
  • Environmental and temperature resistance from -40°F to 300°F (-40°C to 149°C), including resistance to moisture, weathering and indirect UV exposure.

Applications / Suitable for

  • Thermoplastic and thermoset plastic bonding
  • ABS, acrylic and polycarbonate assemblies
  • FRP, urethane, phenolic, polysulfone and vinyl bonding
  • Prepared metal-to-plastic assemblies

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
20,000 - 70,000 mPa.s
Thermal Properties
Flash Point
The flashpoint of a solvent is the lowest possible temperature at which it can vaporize to form an ignitable vapor. Flashpoint is often confused with “autoignition temperature”, which is the temperature at which a solvent ignites without an ignition source.
