Medium Density Overlay (MDO)
Dura-Max Concrete Grade
Paneltech’s Dura-Max Conform MDO is a high resin content specialty overlay. While it is cured sufficiently to reduce sticking in the press, it still exhibits the desirable properties of a high flow MDO. The combination of high resin content with a melamine saturating resin formulated to resist the action of alkaline concrete fluids gives Dura-Max the extra hardness to give unsurpassed performance concrete forming applications. It gives a smooth, matte finish to concrete finish and is treated to release easily from forms when coated with the appropriate form oil. The higher melamine resin content, other things being equal, will give more pours on average than a standard MDO.
Dura-Max is unique in the ability to absorb water-based form releases. This is a very important safety feature in deck-pour applications. The paper is well saturated with resin to ensure a high form life and to prevent internal paper delamination. This high internal bond is unique to Paneltech’s overlays and is quite important for concrete forming applications.
As with other Paneltech MDO products, Dura-Max has a proprietary phenolic glue line formulation that gives it strong adhesive properties when bonding to all commonly used wood substrates. Dura-Max exceeds the requirements of the PS1-19 Voluntary Product Standard.
