An Adhesive for Bonding Internal Boat Structures
Huntsman is a brand that has developed versatile, innovative and reliable solutions for the naval and marine industry for over 70 years. All of their adhesive solutions focus on efficiency and reduction of manufacturing costs, making it possible to achieve more reliable joints and save up to 50% in production time when joining internal vessel structures. In addition, these adhesives enable unique design features, combining robustness for commercial vessels and lightweight construction for yacht programs. In addition, its structural adhesives make it possible to join large parts, repair in wet conditions, while ensuring good performance.
The Challenge: Replacing & Sealing the Inner Lamination
Araldite 2023-30 is an ideal choice for replacing and sealing the internal lamination of the boat hull. This product is 100% non-sagging, which means it can be easily applied on complex surfaces, both vertical and elevated. The panel is pre-positioned without the need to apply primer and the adhesive is injected, acting as a structural load bearer and sealant at the same time. The combination of primerless application and a one-step bonding process can speed up the process by up to 50% and result in a cleaner assembly compared to the traditional lamination process.
The Solution: Araldite 2023
Araldite 2023 is a two-component adhesive. It is a flexible product for joints where high filling capacity and high resistance are required. It is suitable for joining internal vessel structures. The adhesive combines the properties of high elongation at break and gap filling capacity; allowing it to firmly bond and seal large parts without hanging. Below we will review the main characteristics of this product:
- Modular cure: Available from 10 to 60 minutes for a correct open time/cure ratio.
- High filling capacity: Compensates for gaps of up to 30 mm.
- UV stable: Maintains a bright grey colour that will not yellow with age or sun exposure.
- This sticker is in the process of being endorsed by Lloyd’s Register in 2020.
- It is flexible and compensates for the thermal expansion of different materials and dynamic loads.
- Does not drop: It can be applied to complex geometries, verticals and elevated surfaces.
