Scigrip says that its composite bonding products have been used by Italian yacht manufacturer Ferretti.
Ferretti and Scigrip distributor Mastikol looked into replacing classic polyester-based adhesives with Scigrip’s methacrylate adhesives to bond a glass fiber hull shell and the structural elements, specifically those of the engine room and other key load bearing parts, that are laminated off-line and built off-site.
Mastikol used Scigrip’s Lloyd’s approved SG230 HVA adhesive, supplied in 189 litre drums. This high viscosity, thixotropic adhesive can also be applied in void free bead sizes up to 80 mm. Different hardener speeds were supplied allowing customised working times to match the required joining times. Given the large bonding surface area, it was necessary to use an application system that dispenses a large quantity of product in the shortest possible time. Mastikol and Scigrip also specified a special drum extruder to dispense the product.
The companies sat that they are looking to further improving the production process in the future, which could reduce the surface preparation stage and make use of the adhesive’s capacity to adhere to smooth, gel-coated and moist surfaces, reducing production cycle time and dust.
