MDO plywood features highly durable, resin-impregnated fiber faces. The thermoset resin, bonded under heat and pressure, forms a very tough surface that easily resists abrasion, moisture penetration, chemicals, and deterioration and is far more durable than standard plywood. it is ideal for use in the most punishing of applications. It retains plywood's advantages, such as high strength to weight ratio, dimensional stability, and rack resistance, as well as plywood's design flexibility, and can be worked with common woodworking tools.
