SCIGRIP SG200 methacrylate adhesive technology serves in critical bonding and sealing applications and enhances the performance of recreational and fishing paddle boards, as well as other personal watercraft manufactured by Dragonfly Boatworks. The paddle boards’ unique two-piece “shoe box” design consists of a hull and a top deck that are mated with SCIGRIP’s SG200 Series adhesive in a 6mm bond line, ensures the bond strength to keep the two pieces together, and prevents water from entering the board’s internal section. Due to the unique rheology of SG200-40, no additional sealing st EPS are required after the hull pieces are joined.
SCIGRIP’s SG200 series adhesives are two-component, 10:1 mix ratio products used for bonding composites, thermoplastics, metals and combinations thereof. The SG200 Series requires minimal surface preparation and offers a choice of 10-, 20- and 40-minute working times. SG200-40 helps maximize manufacturing efficiency by providing Dragonfly Boatworks with the production time needed in order to bond the two-piece boards and ensure a precision seal, according to the company.
Dragonfly Boatworks’ 10-foot and 13.6-foot paddle boards are used for fishing, exercise and recreation, offering the ability to enter typically non-accessible, shallow waters. Additionally, Dragonfly boards are configured to keep the paddle boarders dry with their unique water- shedding deck design.
Adhesion properties of SG200 Series adhesives include a tensile strength of 2,000 – 2,500 psi (14 – 17 MPa); lap shear strength of 2,400 – 2,800 psi (16 – 19 MPa); and tensile modulus of 60,000 – 75,000 psi (413 – 517 MPa), measured at 24°C.
The SG200 series products are widely used for marine, transportation and general plastic bonding applications. Packaging options include 490 ml cartridges and 19 and 189 litre bulk containers for application with meter-mix dispense equipment.
