MDO plywood stands for Medium Density Overlay plywood. It is a type of plywood that is engineered for specific applications where a smooth and durable surface is required. MDO plywood is commonly used in outdoor and construction projects due to its excellent strength, weather resistance, and ability to hold paint well.
Here are the key features and characteristics of MDO plywood:
Overlay: MDO plywood has a surface overlay made of resin-impregnated fiber. This overlay is typically composed of a layer of kraft paper or a thin layer of phenolic resin-impregnated film. The overlay provides protection and enhances the surface properties of the plywood.
Medium Density Core: The core of MDO plywood is made of wood veneers that are bonded together with adhesives. The core is of medium density, providing a balance of strength and weight.
Smooth Surface: The overlay on MDO plywood creates a smooth and uniform surface that is free from knots, voids, and patches. This makes it suitable for applications where a smooth finish is desired, such as for signs, outdoor furniture, and architectural elements.
Weather Resistance: MDO plywood is engineered to withstand outdoor conditions. The overlay protects the plywood from moisture, UV rays, and other weather elements, making it more resistant to warping, delamination, and decay.
Paintability: MDO plywood has excellent paint adhesion properties. The smooth surface and resin overlay make it easy to achieve a high-quality paint finish. The plywood can be painted, stained, or coated with various finishes to achieve the desired aesthetic appearance.
Strength and Durability: MDO plywood exhibits good structural strength and durability. The cross-laminated construction of the core enhances its stability and resistance to bending, impact, and shear forces.
Applications: MDO plywood is commonly used in outdoor applications, including signboards, billboards, exterior cladding, sheds, fencing, and concrete formwork. It is also suitable for interior applications that require a smooth and durable surface, such as cabinets, furniture, and wall paneling.
It's worth noting that MDO plywood may be available in different grades, thicknesses, and sizes to meet specific project requirements. When using MDO plywood, it is essential to follow manufacturer guidelines and consult local building codes and regulations for proper installation and application.
