Loctite 404 Instant Adhesive 9.3g / 0.33oz

Loctite 404 is a low viscosity, transparent ethyl cyanoacrylate adhesive. It is designed for the bonding of plastic and rubbers where very fast fixturing is required. The product is 1-part and cures at room temperature. Loctite 404 is suited for general maintenance. Typical applications include rubber O-ring bonding and mounting plastic labels and nameplates.

Loctite 404 develops full strength in a very short time. However, curing continues for at least 24 hours, before full chemical  resistance is developed. Width of the bondline gap and ambient humidity both affect curing speed.

• Very fast fixturing
• Low viscosity
• Colourless to straw colour
• Recommended for thin bond gaps (0.05 mm)
• Qualified to Commercial Item Description A-A-3097 (This is a regional approval)

How to use Loctite 404:

1. Clean surfaces before applying the product.
2. To improve bonding on low energy surfaces, Loctite 770 primer may be applied. Allow it to dry.
3. Loctite activator may be used if necessary. Apply it to one bond surface. Do not apply activator to a primed surface. Allow it to dry.
4. Apply Loctite 404 to one of the bond surfaces. Do not apply on the activated surface. Do not spread the adhesive with a tissue or brush.
5. Assemble components carefully. The short fixture time leaves little opportunity for adjustment.
6. Hold together or clamp bonds until the adhesive has fixtured.
7. Allow product to develop full strength before subjecting to any service loads. This will usually take between 24 and 72 hours.

Storage

Store Loctite 404 in the unopened container in a dry location. Optimal Storage: 2° C to 8° C. Storage below 2° C or greater than 8° C can adversely affect product properties.
