Loctite 406 - 20 g (instant adhesive)

Product description:
LOCTITE 406 is designed for bonding of plastics and elastomeric materials where very fast fixturing is required. The rate of cure will depend on the bondline gap. Thin bond lines result in high cure speeds, increasing the bond gap will decrease the rate of cure. The rate of cure will depend on the ambient relative humidity. The best results are achieved when the relative humidity in the working environment is 40% to 60% at 22°C. Lower humidity leads to slower cure. Higher humidity accelerates it, but may impair the final strength of the bond. Where cure speed is unacceptably long due to large gaps, applying activator to the surface will improve cure speed. However, this can reduce ultimate strength of the bond and therefore testing is recommended to confirm effect. Further information about the product can be obtained from your local technical department:

Steps to achieve the best adhesive results:
1. Bond areas should be clean and free from grease. Clean all surfaces with a LOCTITE 7063 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. Activator LOCTITE 7455 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. Activator LOCTITE 7455 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).

Store product in the unopened container in a dry location. Storage information may be indicated on the product container labeling.
Optimal Storage: 2 °C to 8 °C. Storage below 2 °C or greater than 8 °C can adversely affect product properties.
Material removed from containers may be contaminated during use. Do not return product to the original container.
Henkel Corporation cannot assume responsibility for product which has been contaminated or stored under conditions other than those previously indicated.
