Soudal 65A Wood Adhesive is formulated with polyvinyl acetate (PVAc), presenting a high viscous fluid consistency that is perfect for woodworking. The adhesive is designed to physically dry, achieving a solid content of approximately 50%. It offers an optimal open time of about 8 minutes at 23°C and 55% relative humidity, allowing sufficient workability before setting. The minimum film-forming temperature (MFFT) stands at 5°C, facilitating application in cooler conditions without losing effectiveness.
This wood adhesive undergoes a physical drying process, where it transitions from a viscous fluid to a strong, transparent film once cured. The pressing pressure required ranges from 1 kg/cm² to 2 kg/cm², making it adaptable to various clamping setups. With its D3 water resistance rating according to EN204, Soudal 65A can withstand exposure to high moisture environments, making it a reliable choice for areas not directly exposed to the elements but still subject to high humidity.
Soudal 65A is easy to apply with a brush, roller, or adhesive applicator. It is especially effective for full surface bonding, with a recommended consumption rate of 80 - 140 g/m², and for assembly, where 160 - 180 g/m² is advised. This adhesive is characterised by its fast drying time and resistance to high temperatures, ensuring quick completion of projects and long-lasting durability.

Soudal 65A Wood Adhesive is suitable for use on a wide variety of substrates including porous and non-porous surfaces such as wood, carton, laminate, and more.
For effective bonding, the materials should ideally be flat, well-fitting, and compatible with PVA adhesive.
It is crucial that the adhesive performs adequately on non-traditional or mixed materials, hence, conducting a preliminary adhesion test is strongly advised to ensure compatibility and optimal bonding strength.
Thorough surface preparation is key to achieving the best results with Soudal 65A. Ensure that all surfaces to be bonded are clean, dry, and free from dust, grease, or any other contaminants that might impair adhesion. For non-porous surfaces, slightly grinding or sanding can enhance the adhesive's grip. This step is particularly important when dealing with laminates or coated materials where surface smoothness can prevent effective adhesion.
Soudal 65A can be applied using a notched trowel, brush, or via automated adhesive application machines, making it versatile for various project sizes and requirements.
Apply a uniform coat of the adhesive to one of the surfaces to be bonded. It is not necessary to apply adhesive to both surfaces, but coverage should be complete on the chosen application surface. Once the adhesive is applied, quickly align and join the parts together.
After joining, the materials should be firmly clamped. Clamping ensures that the adhesive is evenly distributed and that the bond remains undisturbed during the initial setting period.
The duration of clamping can vary depending on the materials used and the environmental conditions but generally ranges from 1 to 2 hours. Ensure that the clamping pressure is evenly distributed across the joint.
The curing time of Soudal 65A is influenced by several factors including the type of wood, ambient temperature, adhesive volume, and substrate porosity.
Typical pressing times for high-frequency bonding with longitudinal heating are greater than 15 seconds. For decorative finishes, pressing times can be as short as 5-10 seconds.
For assembly bonding, pressing times range from 8-15 minutes. Joints and block bonding require 10-15 minutes under pressure.
When bonding HPL/CPL to plywood in short cycle presses at 70°C, the pressing time is approximately 90 seconds, and for chipboard, it is around 45 seconds.
After the pressing time is complete, remove clamps and inspect the bond for any signs of adhesive squeeze-out or misalignment before the adhesive fully cures. Any excess adhesive should be wiped away with a damp cloth before it dries.
Tools and excess adhesive should be cleaned with water immediately after use. Once Soudal 65A has cured, it can only be removed mechanically. This means any residue left behind after the adhesive has set will need to be scraped or sanded off.
