Coosa Bluewater 26 Series Composite Board
Coosa Bluewater 26 Series is a premium fiberglass-reinforced polyurethane composite panel designed for demanding marine, industrial, and structural applications. Combining exceptional strength with significantly reduced weight, Bluewater 26 is a superior alternative to traditional plywood where long-term durability and moisture resistance are critical.
Unlike wood, Coosa Bluewater 26 will not rot, absorb water, warp, or delaminate, making it ideal for harsh marine environments and high-moisture applications. Its closed-cell composite construction resists mold, mildew, insects, and decay while delivering excellent dimensional stability and long-lasting structural performance.
Bluewater 26 is easy to fabricate using standard woodworking tools and bonds exceptionally well with polyester, vinyl ester, and epoxy resin systems. Its outstanding strength-to-weight ratio makes it the preferred choice for professional boat builders, repair shops, and DIY marine restoration projects.
