G5 FIVE MINUTES ADHESIVE

What is G5 Five Minutes Adhesive and why choose it?

G5 Five Minutes Adhesive by West System is a two-part, fast-setting epoxy system designed for quick repairs, tooling and general bonding tasks where speed and ease of use are essential. With a simple 1:1 mix ratio and a pot life of around 4 minutes, it develops handling strength in minutes, making it ideal for spot repairs, positioning components and small bonding jobs in workshops, on boats or at home.

Main features

• Fast-setting epoxy system: 5-minute epoxy adhesive that reaches handling strength in a very short time, suitable for rapid interventions.
• Two-part resin and hardener: easy 1:1 mix ratio by volume for straightforward, repeatable use.
• Versatile bonding: designed to bond metals, wood, concrete, stone, ceramics, glass, GRP and other typical construction and repair substrates (information based on manufacturer data but not independently verified).
• Convenient for small jobs: ideal for spot applications, quick fixes and holding parts in position while longer-cure epoxies are applied.
• Amber colour: cured adhesive has an amber appearance, useful for visual inspection of the bond line.
• Speciality epoxy from West System: part of the West System speciality epoxy range, developed for adhesive applications requiring very rapid curing.

Technical specifications

The following values are indicative and based on publicly available manufacturer information. They may vary depending on conditions and should not be considered guaranteed performance.

• Mix ratio (by volume): 1:1.
• Pot life (100 g at 25 °C): approximately 4 minutes.
• Gel time, thin film at 25 °C: approximately 5 minutes.
• Gel time, thin film at 7 °C: approximately 20 minutes.
• Cure to solid, thin film at 22 °C: approximately 16 minutes.
• Cure to working strength (typical): around 1 hour, depending on temperature and bond thickness.
• Colour: amber.

For exact performance data, curing profiles and limitations, rely on the latest official product documentation from West System.

Applications and use cases

• Home repairs: quick bonding of small components, fixtures and fittings on wood, ceramic, stone or metal surfaces.
• Marine repairs: suitable for temporary or non-critical bonds and spot applications on boats, particularly for holding components while other West System epoxies cure.
• Woodworking: assembling small wood joints, bridging small gaps and securing trim or hardware where a very fast cure is helpful.
• Tooling and workshop use: positioning jigs, fixtures and small parts, or creating quick mock-ups and prototypes.
• General bonding: repairs on materials such as aluminium, steel, GRP, glass, unglazed ceramics, concrete and similar substrates, provided surfaces are properly prepared (cleaned and abraded) and the joint is not permanently exposed to high loads or moisture.

It is generally not recommended for long-term structural bonds in high-load or continuously wet environments; for those, slower-curing structural epoxies from West System are usually preferred.

FAQ – G5 Five Minutes Adhesive

1. Is G5 Five Minutes Adhesive suitable for structural, high-load joints?

   No, this product is typically not recommended for long-term bonds subject to high loads or constant moisture. For structural marine or high-load applications, slower-curing structural epoxy systems from West System are usually more appropriate.

2. What is the mixing ratio of the resin and hardener?

   The adhesive is mixed at a 1:1 ratio by volume (equal parts of Part A resin and Part B hardener). This information is based on manufacturer data and should be confirmed against the latest product documentation.

3. How long do I have to work with the mixed adhesive?

   The pot life of a 100 g mix at approximately 25 °C is around 4 minutes, so only small quantities should be prepared at once to avoid premature gelling.

4. When does the bond reach handling strength?

   In thin film at room temperature, the adhesive typically gels in about 5 minutes and becomes solid in around 16 minutes. Practical handling strength is usually achieved within about an hour, depending on ambient temperature and joint design.

5. On which materials can I use G5 Five Minutes Adhesive?

   According to available manufacturer information, it can bond metals (such as steel, aluminium, copper and cast iron), wood, glass-reinforced polyester, concrete, stone, glass, unglazed ceramic and similar substrates when surfaces are correctly prepared. This list is indicative and should be verified for your specific application.

6. Can it be used outdoors or in wet environments?

   It can be used in many repair contexts, but it is generally not intended as a permanent adhesive for continuously wet or heavily loaded outdoor joints. For demanding marine or exterior applications, consider a more moisture-resistant structural West System epoxy.

7. Can I thicken or modify the adhesive?

   G5 can typically be modified with appropriate West System fillers to adjust viscosity and gap-filling properties. Choice of filler depends on the specific application and should follow manufacturer recommendations.

8. How should surfaces be prepared before bonding?

   Best practice is to degrease with a suitable solvent, abrade the surfaces, remove dust and ensure they are clean and dry before applying the mixed adhesive. Correct surface preparation is essential for achieving good bond strength.

9. Is all the data here fully verified?

   No. The information provided is based on publicly available data from the manufacturer and is intended as a general guide only. For critical applications, always rely on the latest official documentation and safety information supplied by West System.

Section 14 – Transport information

Specific transport classification details for G5 Five Minutes Adhesive (such as UN number, proper shipping name, hazard class, packing group or transport category) are not fully detailed here and may vary by region and packaging format. Users must refer to the most recent official transport and safety documentation of West System and comply with local, national and international transport regulations for chemical products.

Section 8 – Individual protection measures

The following information is general guidance derived from typical practices for two-part epoxy adhesives and may not cover all scenarios. Always adapt protective measures to your actual working conditions.

• Eye and face protection: wear safety goggles or a face shield to prevent splashes from contacting the eyes.
• Skin protection: use suitable chemical-resistant gloves (for example nitrile) and protective clothing with long sleeves to avoid repeated or prolonged skin contact.
• Respiratory protection: in well-ventilated areas, respiratory protection is often not necessary. In poorly ventilated spaces or when heating the product, use suitable respiratory protection as required by workplace risk assessment.
• Hygiene measures: avoid contact with skin, eyes and clothing. Do not eat, drink or smoke while using the product. Wash hands thoroughly after handling, and remove contaminated clothing and protective equipment before entering eating areas.
• Ventilation: work in a well-ventilated area or use local exhaust ventilation to minimise exposure to vapours and fumes, especially when mixing larger quantities.

For precise and binding safety requirements, always follow the latest safety documentation and regulatory guidance applicable in your country.
