Maximises the Effects of Park Tool's Thread Lockers and Retaining Compounds
Park Tool recommends the use of the AP-1 adhesive primer to prep the surface of anything you intend to apply thread-locking or retaining compounds to. Prepping the surface will maximise the effectiveness of these products and greatly reduce their curing times.
Important Note: Any components or fasteners that will come into contact with carbon surfaces such as press fit bottom brackets or bearings must first be treated with the AP-1 primer before applying any thread-lockers or retaining compounds. Failure to do this may result in the parts becoming permanently bonded.
- Preps surface for use with TLR-1, TLR-2 and RC-1 compounds
- Reduces curing times of locking compounds
- Prevents thread-lockers and retaining compounds from causing permanent bonding to carbon surfaces
