Simple Application Instructions

1. Clean: For optimal results, clean all internal and external surfaces to remove dirt, oil, and grease, then let dry.
2. Apply: Apply a small amount of the liquid instant adhesive to one of the mating surfaces (do not spread the glue).
3. Assemble: Align and press the parts together immediately. Hold firmly for about 10 seconds until the fixture is achieved. The formula cures rapidly via humidity activation.

Frequently Asked Questions (FAQ)

What is Loctite 401 used for?

Loctite 401 is a high-strength instant adhesive designed for the rapid assembly and emergency repair of a vast range of materials. It is specifically formulated to prevent component failure by creating a high-strength bond that resists shear and tensile stress on close-fitting parts.

Can Loctite 401 bonds be disassembled?

Because Loctite 401 creates a permanent, high-strength bond, disassembly can be difficult. It typically requires specialized cyanoacrylate de-bonders (like nitromethane or acetone) or mechanical force, depending on the heat resistance and sensitivity of the bonded substrates.

Does Loctite 401 work on porous surfaces?

Yes. Unlike standard super glues that soak into porous substrates, Loctite 401 is highly effective on porous materials such as wood, paper, cardboard, leather, and fabric, alongside smooth surfaces like metals and plastics.

Is Loctite 401 safe for general industrial manufacturing?

Loctite 401 is an industry-standard universal adhesive widely trusted in electronics, automotive maintenance, and general appliance manufacturing due to its reliable, uniform stress distribution and rapid curing time.
