Pipe Doctor resin is supplied in two parts – resin and waterglass – which are activated on mixing.

Three formulations are available, Summer, Winter and Rapid, which give different working times and speed of curing, to suit the ambient temperature when being installed on site (see below).

The Benefits of Pipe Doctor resin include:

  • High temperature resistance
  • Excellent chemical resistance compared to all other pipe repair resins
  • Water-glass based polysilicate resin for strength and flexibility due to unique cross-linked molecular formula
  • Able to cure in the presence of water, for no washout during installation
  • Excellent bonding properties to most materials
  • Excellent migration properties between the resin and fibreglass mat, for consistent impregnation
  • Non-flammable, so ideal for airports, hospitals, stations and other public places
  • Non-hazardous, so no transport or disposal problems
  • Odourless, so ideal in confined spaces

The following curing times and temperatures are based upon ambient conditions and are intended as a guide only:
