LOCTITE® 402 is an ultra-performing, fast-setting instant adhesive that provides reliable performance under extreme operating temperatures up to 275°F/135°C. It allows rapid bonding of multiple substrates including metals, plastics, elastomers, and porous materials such as wood, paper, leather, and fabric.
Bond areas should be clean and free from grease. Clean all surfaces with a LOCTITE® cleaning
solvent and allow to dry. To improve bonding on low energy plastic surfaces, LOCTITE® Primer
may be applied to the bond area. Avoid applying excess Primer. Allow the Primer to dry.
LOCTITE® Activator may be used if necessary. Apply it to one bond surface (do not apply
activator to the primed surface where Primer is also used). Allow the Activator to dry.
Apply adhesive to one of the bond surfaces (do not apply the adhesive to the activated
surface). Do not use items like tissue or a brush to spread the adhesive. Assemble the parts
within a few seconds. The parts should be accurately located, as the short fixture time
leaves little opportunity for adjustment. LOCTITE® Activator can be used to cure fillets of
product outside the bond area. Spray or drop the activator on the excess product. Bonds
should be held fixed or clamped until adhesive has fixtured. Product should be allowed to
develop full strength before subjecting to any service loads (typically 24 to 72 hours after
assembly, depending on bond gap, materials and ambient conditions).
