HIGH DENSITY OVERLAYS (HDO) AND FILMS
Highly saturated papers that are self-bonding to the substrate without a glue coating. Because of their higher resin content, they produce a somewhat glossier surface texture compared with MDO resulting in an “architectural finish” on concrete surfaces. The higher resin gives the HDO and films superior barrier properties and increased resistance to abrasion and alkalinity. HDO can extend panel life up to 20 times over non-overlaid plywood. When would you specify a phenolic over melamine?
