The SCIGRIP Solar Boat competed and came first in its class in the DONG Energy Solar Challenge 2014 hosted in Holland earlier this year.
The boat was constructed at Cree Yacht Design in Poland and SCIGRIP, a global supplier of smart adhesive solutions, sponsored the team and provided on-site technical support and a range of high performance, structural methyl methacrylate (MMA ) adhesives throughout the prototyping phase and build process.
The SCIGRIP Solar Boat crew consists of a dedicated group of engineers with a vast knowledge of the marine industry, composites technology and the application of specialist adhesive products.
SCIGRIP’s two component, high viscosity MMA adhesive, SG 230HV has been used to bond the largest and most demanding joints such as the bulkheads, engine column and floater beam sections. The product has a 10:1 mix ratio with adjustable cure rates ranging from 30 to 120 minutes.
Skipper Bartosz Puchowski states, “SCIGRIP’s adhesives were very straightforward and easy to work with. For the larger structural sections we applied SG230HV which offers a range of working times, is lightweight, easy to apply and exceedingly strong.” For applications where substrates have to bond and cure more rapidly and where unprimed metals might be one of the components, SCIGRIP’s SG300-05 has been applied in areas such as the perimeter of the electrical box. A black formulation of SG300 was also used to bond the deck to the hull, allowing the joint to blend seamlessly and be hidden from view. SG100 White has been used to adhere the structure’s floats to the deck and also provides UV protection and resists discolouration if the glue line is exposed.

SCIGRIP Marine Repair Packs
To highlight their products suitability for marine applications, SCIGRIP issued customised ‘Marine Repair Kits’ to all competitors should any mishaps of occurred on the water.
Each kit contained a selection of high performance, fast curing adhesives as well as waterproof epoxy putty sticks to allow the teams to quickly mend any damage or breakages. These products have been specially formulated to bond easily with composite substrates, wood and a range of metals making them very flexible and suitable for a wide range of applications.
Thanks to the SCIGRIP products rapid cure times and ability to bond quickly with very little surface treatment, many teams were able to complete repairs swiftly and safely despite, in some cases, suffering significant damage to their vessels.
