Chesapeake Plywood provides the highest quality High Density Overlay (HDO) panels for your wholesale needs. HDO adds stability, repels foreign substances from the surface, and provides a smoother and more durable forming surface. The phenolic resins used in overlay productionHDO are hard and resist moisture, chemicals, and abrasion. High Density Overlay (HDO) is often utilized where the smoothest possible concrete finish and maximum number of reuses is desired.
HDO (high density overlay) has a resin content of 52 to 58 percent and appears smoother to the touch than does MDO. Hotels, high rise office buildings, museums, power plants, civil projects, and large-scale residential projects are common applications for HDO concrete forming panels. Panels are manufactured as one-sided or two-sided panels varying in thickness. Contractors can expect 25-50 reuses depending on the application, proper handling, care, and treatment with an appropriate release agent.
High Density Overlay (HDO) impart a nearly polished concrete surface. Both sides of HDO are moisture resistant but cannot always be used to form concrete with equal effectiveness unless specifically made for that purpose.
The abrasion-resistant surface should be treated with a release agent prior to its first use and between each pour to preserve the surface and to facilitate easy stripping.
