Fortis AD5045-S is a single-component, moisture-curing structural polyurethane timber adhesive developed for finger jointing and structural wood bonding.
With a working time of less than 4 minutes, AD5045-S provides additional assembly time compared with faster finger-jointing grades while maintaining rapid processing and excellent production efficiency.
The adhesive provides excellent adhesion to a wide range of timber species, including dense Australian hardwoods, imported hardwoods, Radiata pine and other softwoods. Its moisture-curing polyurethane chemistry produces a strong, water-resistant bond with slight expansion during cure.
AD5045-S is designed for demanding structural timber applications and meets EN 302 / AS/NZS 4364:2010 requirements. It is also certified by the Glued Laminated Timber Association of Australia under GLTAA Certificate #007.
Its combination of structural bond performance, controlled working time and relatively low application rate makes AD5045-S suitable for professional timber processors requiring reliable finger jointing across a range of timber species and production conditions.

Ensure all bonding surfaces are clean, dry and free from dust, oil, grease and other contaminants that may interfere with adhesion.
Fortis AD5045-S is designed for finger-jointing processes and is suitable for a wide range of joint profiles. Comb-style finger joints are commonly used. Accurate machining and close wood-to-wood contact are essential for achieving optimum structural bond performance.
Apply AD5045-S evenly at the application rate specified in the current Technical Data Sheet. A fine water mist applied to the timber may assist the moisture-curing reaction where recommended for the timber species and processing conditions.
Assemble and press the components within the specified working time. AD5045-S provides a working time of less than 4 minutes under specified conditions. Processing times can vary depending on timber species, moisture content, temperature, humidity and production conditions.
During cold weather, maintain the adhesive at an appropriate processing temperature. An adhesive temperature of approximately 20–30°C is recommended for consistent application and cure performance.
For laminating applications, suitable bonding pressure must be maintained during cure. The current product information recommends a minimum pressure of approximately 1400 kPa.
Refer to the current Fortis AD5045-S Technical Data Sheet for application rate, working time, clamping time and complete processing requirements before production use.
Suitable substrates include:
• Australian hardwoods
• High-density hardwoods
• Imported hardwoods
• Radiata pine
• Softwoods
• Solid timber
• Engineered timber products
• Finger-jointed timber
• Suitable structural timber components
Bonding surfaces must be clean, dry and free from dust, oil, grease and other contaminants that may interfere with adhesion.
Excellent wood-to-wood contact is essential for structural bonding. Finger-joint profiles must be accurately machined and provide a close mechanical fit.
Timber moisture content, species, density, temperature and production conditions can influence adhesive cure and bond performance.
Where recommended, a fine water mist may be applied to assist the moisture-curing reaction.
For laminating applications, suitable and consistent bonding pressure must be maintained during cure. Refer to the current Technical Data Sheet for processing requirements.
Production trials should be carried out when introducing new timber species, joint profiles or manufacturing conditions.

What is Fortis AD5045-S used for?
Fortis AD5045-S is a structural polyurethane timber adhesive developed for finger jointing and structural wood bonding.
How is AD5045-S different from AD5025-S?
AD5045-S provides a longer working time, making it suitable where additional assembly time is required during finger-jointing production.
Is AD5045-S a structural adhesive?
Yes. AD5045-S meets EN 302 / AS/NZS 4364:2010 requirements and holds GLTAA Certificate #007.
What timber can AD5045-S bond?
It is suitable for a wide range of timbers including Australian hardwoods, high-density hardwoods, Radiata pine and other softwoods.
Is AD5045-S suitable for hardwood finger jointing?
Yes. It is particularly suited to finger jointing hardwood and other suitable timber species.
What is the working time of AD5045-S?
The current specification lists a working time of less than 4 minutes. Processing time can be influenced by temperature, humidity and timber conditions.
Does AD5045-S require mixing?
No. It is a single-component, moisture-curing polyurethane adhesive.
Why is water misted onto the timber?
Where recommended, a fine water mist provides additional moisture to assist the polyurethane curing reaction.
Does AD5045-S expand during curing?
Yes. The adhesive produces slight expansion as it cures.
Where can I find processing instructions?
Refer to the current Fortis AD5045-S TDS for application rate, working time, clamping and processing requirements.
