Description
The 3M™ Scotch-Weld™ Instant Adhesive Primer AC79 (7100039262) is a surface preparation solution designed to improve the bonding of cyanoacrylate adhesives on low surface energy substrates such as EPDM, silicone, and other elastomers. It promotes adhesion on challenging materials where standard bonding may be insufficient. The primer features a fast-drying formulation and is easy to apply, making it ideal for production and repair environments that require efficiency and reliability. Supplied in 2 fl oz bottles (10 per case), it is commonly used alongside 3M™ Scotch-Weld™ instant adhesives such as PR100 and PR1500.
