SCIGRIP Technology Enhances Personal Watercraft

SG200 Series Methacrylate Adhesives from SCIGRIP Provide Permanent Bonding Power for Dragonfly Boatworks’ Paddle Boards.

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 .25” 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 steps are required after the hull pieces are joined.

“SCIGRIP’s SG200-40 adhesive is ideal for our paddle boards because of how it creates a lightweight, yet strong adhesive bond,” said Mark Castlow, owner of Dragonfly Boatworks, LLC.  “Using SG200-40 has improved our paddle board’s performance and reduced labor and production cycle times."

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.

“The SG200 Series is part of SCIGRIP’s comprehensive offering of high-performance marine adhesive technologies,” explained Kirk Miller, SCIGRIP’s regional sales manager. “Delivering superior adhesion and sealing properties, while requiring minimal surface preparation, the SG200 Series can be used for bonding a wide range of materials in personal watercraft applications.”

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 75°F/24°C.

The SG200 series products are widely used for marine, transportation and general plastic bonding applications. Packaging options include 490 ml cartridges and 5 or 50 gallon (19 and 189 liters) bulk containers for application with meter-mix dispense equipment.
