Generally, Seaboard® is a difficult product to adhere to itself or other substrates due to the low surface energy of HDPE. There are a couple of adhesive systems that are proven effective: two part epoxy and two part acrylic systems. Lap shear strength values of greater that 1,000 psi have been achieved. Seaboard® has been successfully bonded to itself, wood, aluminum, fiberglass and gelcoat.
A clean, dry and oil free surface is required for good bonding. Always follow the adhesive manufacturer’s recommended procedures and test a small piece before starting production. Recommended adhesives are DP 8005 and DP 8010 both are manufactured by 3M™.
Screwing, Nailing, Stapling
Fastening Seaboard® can be accomplished using all types of screws. A course thread deck screw yields good holding power. Seaboard® has been tested in accordance to ASTM 1761. The screw pull in lbs is 1,134.
Seaboard® can also be fastened using nails and staples.
