The Park Tool AP-1 Adhesive Primer prepares the surface, accelerates curing, and promotes maximum performance of Park Tool TLR-1 and TLR-2 Threadlockers as well as RC-1 Retaining Compound. This primer competes with Loctite® 7649™.
The Park Tool AP-1 Adhesive Primer must be used on all component surfaces in conjunction with threadlockers and retaining compounds that contact carbon fiber such as PF30 bottom brackets or brackets or bearings pressed into carbon fiber frames. Failure to do so could result in permanently bonded parts. Some painted surfaces can be sensitive to threadlockers, retaining compounds, and primers. Test first on an inconspicuous area to see if it causes a stain or discoloration. Clean off any excess from painted surfaces immediately.
