Directions for use:

1. Bond areas should be clean and free from grease. Clean all surfaces with a Loctite cleaning solvent and allow to dry.

2. 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.

3. 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.

4. 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.

5. LOCTITE Activator can be used to cure fillets of product outside the bond area. Spray or drop the activator on the
excess product.

6. Bonds should be held fixed or clamped until adhesive has fixtured.

7. 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).
