MEDIUM DENSITY OVERLAYS (MDO)

Heavy kraft paper based products that are first saturated and cured, then coated with our own PetroFree™ phenolic glue resin for application directly to hardwood or softwood plywood in a hot press. Paneltech’s standard MDO products meet the requirements of PS 1-07 and have been certified by the APA.

Originally developed for sign painting and concrete formwork industries, MDO is also used for other applications as a paintable surface. Paint finishes on MDO are up to three times more durable than the same finish applied to ordinary plywood.

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.
