407 C

Medium Density Overlay (MDO)
407C Concrete Grade

Paneltech’s 407C Conform MDO is a high resin content specialty overlay. While it is cured sufficiently to reduce sticking in the press, it still densifies under heat and pressure and exhibits the desirable properties of a high flow MDO. The combination of high resin content with a resin formulated to resist the action of alkaline concrete fluids gives 407C unsurpassed performance in concrete forming applications. It gives a smooth, matte finish to concrete and is treated to release easily from forms when coated with the appropriate form oil. The higher resin content, other things being equal, will give more pours on average than a standard MDO with a lower resin content.

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, 407C has a proprietary glueline formulation that gives it strong adhesive properties when bonding to all commonly used wood substrates. MDO 407C exceeds the requirements of the PS1-19 Voluntary Product Standard.
