DENSETEC MARINE

Densetec Marine Board is specially formulated to withstand the rigors of harsh outdoor marine environments. It is UV-stabilized to resist damage and retain its beauty, even after years of direct sunlight. Increasingly, Densetec Marine Board is replacing wood and laminates in boating applications. It does not splinter,crack, delaminate, rot, swell, or absorb water like traditional materials. Even under heavy foot traffic on yacht decks, it remains virtually maintenance-free. In addition, there is no need to stain or paint Densetec Marine Board every few years. The color is integrated with the polymer and retains its vibrant appearance better than painted wood. Fabricating and finishing are easy with standard woodworking tools. Densetec Marine Board forms easily for smooth curves and bends. Since there is no grain pattern, parts can be cut from any part of the sheet virtually eliminating waste for greater economy than wood. Densetec Marine Board is also available in two other formulations for specific applications: Densetec Marine HP (High Performance) and Densetec Marine LW (Lightweight).
