Sikadur-330 is a 2-component, thixotropic, epoxy based impregnating resin and adhesive.

  • Easily mixed and applied by trowel and impregnation roller.
  • Manufactured for manual saturation methods.
  • Excellent application behaviour to vertical and overhead surfaces.
  • Good adhesion to many substrates.
  • High mechanical properties.
  • No separate primer required.
Usage
Sikadur-330 is used as:
  • Impregnation resin for SikaWrap fabric reinforcement for the dry application method.
  • Primer resin for the wet application system.
  • Structural adhesive for bonding Sika CarboDur plates into slits.

The pot-life begins when the resin and hardener are mixed. It is shorter at high temperatures and longer at low temperatures. The greater the quantity mixed, the shorter the pot-life. To obtain longer workability at high temperatures, the mixed adhesive may be divided into portions. Another method is to chill components A+B before mixing them (although not below +5 °C).
