TECHNICAL DATA & INFORMATION – Click to view complete technical

  • Low modulus urethane staking compound
  • Pre-measured kits


APTEK 2205-A/B is a thixotropic, two-component, electrically insulating, low modulus urethane system designed for the staking of electrical/electronic components to printed circuit boards. Although APTEK 2205-A/B is capable of achieving full cure at room temperature, a short term exposure to moderate heat will greatly reduce processing time
and optimize cured properties.


  • Provided in easy-to-use pre-measured kits to minimize handling and processing
  • Good wet strength holds components in place allowing for the movement of the circuit boards during processing
  • 100% solids, solvent free system that will not form voids during cure or service life
  • Low Tg for excellent low-temperature cycling and performance
  • Very good substrate adhesion; superior to silicones
