Typically recommended to activate passive metals or inert surfaces and for applications with large bond gaps. Acetone/isopropanol-based 7471 Locquic®. Primer T is used to generally enhance the cure speed of anaerobic adhesives and sealants. To apply, simply spray or brush on both mating surfaces to be bonded. Then allow the solvent time to evaporate under good ventilation until the surfaces are completely dry. After activation, parts should be bonded within 7 days.
