LOCTITE® 401 Instant Adhesive | 25ml | Medium Viscosity | General Purpose Cyanoacrylate

Fast-Curing General-Purpose Instant Adhesive for Metals, Plastics, Elastomers, Porous and Absorbent Materials

Supply Solutions Group supplies LOCTITE® 401 Instant Adhesive – 25ml to organisations operating across manufacturing, engineering, automotive, maintenance, electronics, fabrication, construction and industrial workplaces throughout Australia.

LOCTITE 401 is a general-purpose instant cyanoacrylate adhesive developed for fast bonding across a broad range of compatible materials.

Designed for applications requiring rapid fixture and strong adhesion, LOCTITE 401 is particularly useful for assembling small components and bonding close-fitting parts where a convenient single-component instant adhesive is preferred.

The adhesive is suitable for bonding a wide variety of materials, including appropriate metals, plastics and elastomers.

One of the distinguishing characteristics of LOCTITE 401 is its suitability for porous or absorbent materials, extending its usefulness to applications involving materials such as wood, paper, leather and fabric where appropriate.

Its medium-viscosity consistency provides greater application control than very low-viscosity instant adhesives while still allowing the adhesive to spread effectively between close-fitting mating surfaces.

LOCTITE 401 is a one-component adhesive, so no separate resin, hardener or mixing process is required.

The adhesive cures rapidly when confined between closely fitting surfaces, with atmospheric moisture helping initiate the cyanoacrylate curing process.

This rapid-curing technology can help reduce assembly time in manufacturing, maintenance and repair operations where components need to reach handling strength quickly.

LOCTITE 401 is particularly useful for small-part assembly, component bonding, general repairs, production work and maintenance applications.

The convenient 25ml bottle provides a practical size for workshops, maintenance departments, service technicians and production environments requiring controlled quantities of instant adhesive.

This listing contains 1 × 25ml bottle of LOCTITE 401 Instant Adhesive.

As an Indigenous-owned industrial supplier and procurement partner, Supply Solutions Group provides LOCTITE adhesives, threadlockers, retaining compounds, gasket products, sealants, anti-seize compounds and industrial maintenance consumables backed by responsive customer service, procurement support and Australia-wide business supply capability.

Why Choose LOCTITE® 401 Instant Adhesive?

LOCTITE 401 provides a versatile solution for organisations requiring a fast-curing general-purpose adhesive capable of bonding many different materials.

Unlike two-component adhesives, LOCTITE 401 requires no mixing.

The adhesive is applied directly from the bottle to one of the mating surfaces before the components are assembled.

Its cyanoacrylate chemistry cures rapidly in the presence of small amounts of surface moisture, helping components achieve handling strength quickly.

This makes LOCTITE 401 particularly valuable for production environments and maintenance tasks where waiting for a conventional adhesive to cure could slow down the job.

Another important characteristic is its broad substrate range.

LOCTITE 401 is designed for bonding compatible:

• Metals

• Plastics

• Elastomers

It is also particularly suited to porous or absorbent materials.

This gives technicians and assemblers a versatile adhesive for jobs involving combinations of different substrate types.

The medium-viscosity formulation provides useful application control, making the adhesive suitable for appropriate close-fitting components without being as free-flowing as very low-viscosity grades.

For workshops and industrial maintenance teams, the compact 25ml bottle provides a convenient quantity that can be stored with other frequently used maintenance adhesives.

Fast Instant-Bonding Technology

LOCTITE 401 uses cyanoacrylate instant-adhesive technology.

Cyanoacrylates cure when the adhesive is confined between mating surfaces and exposed to trace moisture naturally present on those surfaces.

This allows rapid bonding without:

• Mixing two components

• Adding a separate hardener

• Applying external heat for normal curing

• Using complex dispensing equipment for straightforward applications

Actual fixture and cure times vary according to substrate, bond gap, environmental conditions and application.

Always refer to the current Henkel Technical Data Sheet when specific cure-performance values are required.

Medium-Viscosity Formulation

LOCTITE 401 is commonly classified as a medium-viscosity instant adhesive.

This makes it useful where operators require a balance between:

• Adhesive flow

• Application control

• Surface wetting

• Close-fitting component bonding

Correct bond-gap selection remains important because cyanoacrylate adhesives generally perform best on relatively close-fitting surfaces.

Broad Substrate Compatibility

LOCTITE 401 is designed for general-purpose bonding across a broad range of compatible substrates.

Metals

Suitable applications may include appropriate:

• Steel components

• Metal fittings

• Small metal assemblies

• Mechanical components

Plastics

LOCTITE 401 can bond many compatible plastics.

Some low-surface-energy plastics can be difficult to bond and may require specialised surface preparation or a compatible LOCTITE primer.

Always confirm compatibility with the specific plastic before production use.

Elastomers

The adhesive can be used on compatible elastomeric materials where instant bonding is required.

Porous and Absorbent Materials

LOCTITE 401 is particularly suited to appropriate porous materials, including:

• Wood

• Paper

• Leather

• Fabric

Actual bond performance depends on the specific material, surface condition and application.

General Application Guidance

For effective bonding:

1. Ensure mating surfaces are clean and appropriately prepared.

2. Remove oil, grease, dust and other contamination where necessary.

3. Confirm that LOCTITE 401 is compatible with both substrates.

4. Apply a small appropriate quantity of adhesive to one surface.

5. Bring the mating components together promptly.

6. Hold or fixture the parts until sufficient handling strength develops.

7. Allow the assembly to cure according to Henkel recommendations before applying service loads.

Excessive adhesive generally does not improve cyanoacrylate bond performance.

Follow the current LOCTITE Technical Data Sheet for detailed application guidance.

Surface Preparation

Clean surfaces are important for reliable adhesive bonding.

Before applying LOCTITE 401:

• Remove dirt and loose contamination

• Remove excessive grease and oil

• Ensure surfaces are appropriately dry

• Check material compatibility

• Prepare difficult-to-bond substrates where required

• Use only compatible cleaners and primers

Some plastics and elastomers may require specialised surface treatment.

Where bond performance is critical, validate the complete bonding process under actual production conditions before implementation.

Important Material Considerations

LOCTITE 401 is highly versatile, but no instant adhesive is suitable for every material or assembly.

Users should confirm compatibility before application, particularly with:

• Low-surface-energy plastics

• Sensitive plastics

• Specialised elastomers

• Coated surfaces

• Painted components

• Components exposed to unusual chemicals

• Assemblies exposed to demanding temperature conditions

For difficult-to-bond plastics or elastomers, Henkel offers primers and alternative adhesive grades designed for specialised applications.

Important Safety Information

LOCTITE 401 is a cyanoacrylate instant adhesive and must be handled according to the current Henkel product label and Safety Data Sheet.

Cyanoacrylate adhesives bond skin and eyes rapidly.

Users should:

• Read the current product label and SDS before use

• Avoid contact with skin

• Avoid contact with eyes

• Avoid breathing excessive vapour

• Use with appropriate ventilation

• Wear appropriate PPE identified by the SDS and workplace risk assessment

• Keep the container closed when not in use

• Store according to Henkel instructions

• Keep away from children

• Follow workplace chemical-handling procedures

Do not forcibly pull apart accidentally bonded skin. Follow the first-aid instructions contained in the current Safety Data Sheet.
