ThistleBond A & B Cement is a high performance multipurpose epoxy adhesive specifically developed for repairs wheredifficult adhesion conditions exist.
ThistleBond A & B Cement is formulated on a complex range of epoxy resins combined with a polyamino curing system reinforced with inert fillers to enhance the adhesion properties of the whole system.
ThistleBond A & B Cement can be applied to virtually any surface to form an effective bond. In addition to being used as an adhesive ThistleBond A&B Cement can also be used to fill cracks in components and castings prior to application of ThistleBond Resin Repair Systems.
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.
ThistleBond A &B Cement is a two component solvent free material comprising resin and hardener components which must be mixed together prior to use.
Measure 1 volume of resin component and 1 volume hardener component onto a clean mixing board or other suitable surface. The two components should then be thoroughly mixed until completely streak free.
The mixed material should be used within 20 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 A & B Cement 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 A & B Cement begins to cure.
Where a ThistleBond repair is to be carried out on a cracked pipe or plate then ThistleBond A & B Cement should be trowelled into the crack before proceeding with the repair. Where the crack is still leaking a little, then it is recommended that ThistleBond A & B Cement should be left to cure partiably before being retrowelled into the crack.
