LOCTITE® 383

Features and Benefits

High strength, high viscosity, thermally conductive, modified acrylic adhesive designed for bonding heat generating components to heat sinks.
LOCTITE® 383 is a gray, high strength, high viscosity, thermally conductive, modified acrylic adhesive designed for bonding heat generating components to heat sinks. This product should be limited to a maximum of 500 V in high pot applications. Typical applications include bonding transformers, transistors and other heat generating electronic components to PCB assemblies or heat sinks.
  • High strength
  • High viscosity
  • High thermal conductivity provides excellent heat dissipation for thermally sensitive components
  • Controlled strength permits field and service repair
