ThistleBond Plastic Bronze is a high performance multi purpose metal repair compound specifically
developed for onsite repairs of damaged or faulty castings, corroded pumps, valves, pump or shafts
ThistleBond Plastic Bronze is formulated on a complex range of epoxy resins combined with a polyamino
curing system which is reinforced with inert pigments and bronze fillers to produce a pourable paste which has excellent resistance to corrosive liquids and gasses.
ThistleBond Plastic Bronze is ideally suited for use in tool rooms providing an economical solution to the problem of producing short run or prototype dies, jigs and fixtures.
ThistleBond Plastic Bronze is simple and easy to use, can be drilled, tapped or filed etc. just like the parent metal.
Before proceeding, please read the following information carefully to ensure that the correct application
procedure is fully understood.
Heavy contamination due to oil or grease must first be removed using ThistleBond Cleaner.
All loose material, rust and surface contaminants, including existing coatings, must be removed and the surface roughened by using an angle grinder, needle gun or abrasive blasting. Where grinding or needle gunning is used, the surface should be cross-scored to improve adhesion. Care must be taken, when
angle grinding, to avoid polishing rather than roughening metal surfaces.
Where possible, abrasive blasting is the preferred surface preparation, especially in fluid flow repairs.
Surfaces should finally be carefully degreased using ThistleBond Cleaner. Cloths should be frequently changed to avoid spreading contamination. On deeply pitted surfaces or porous castings, ThistleBond Cleaner should be worked into the surface by brush and washed off using excess cleaner.
ThistleBond Plastic Bronze is a two component solvent free material comprising resin and hardener components which must be mixed together prior to use.
The mixed material should be used within 30 minutes of mixing at 20°C (68°F). This time will be reduced at higher temperatures and extended at lower temperatures.
The mixed material should be pressed firmly onto the prepared area, working the material into any cracks and surface defects. When ThistleBond Plastic Bronze is being used to bond two surfaces together, both surfaces should be coated with the material. The two pieces should then be pressed firmly together
and clamped in position until the product has set, any excess material squeezed out should be scraped away before the ThistleBond Plastic Bronze begins to cure.
When a reinforcing Tape is being used to strengthen the repairs the tape should either be impregnated with ThistleBond Plastic Bronze, or the tape should be layed over the ThistleBond Plastic Bronze surface and stippled into the material before it cures, then additional ThistleBond Plastic Bronze applied over the surface.
