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)
LOCTITE® 401 is a quick curing instantaneous adhesive designed for the meeting of difficult-to-bond substances requiring uniform stress distribution and excessive tensile and/or shear strength. The product presents for the fast bonding of a extensive vary of materials, such as metals, plastics and elastomers. LOCTITE 401 is additionally suitable to bonding porous substances such as wood, paper, leather-based and fabric. Perfect for all speedy repairs and all sorts of small emergency repairs.
