Medium density overlay panel, or MDO panel, is a paintable surface made of plywood with a weather-resistant resin overlay bonded to the wood by heat and pressure. The overlay, which has at least 27% resin content, [1] resists water, weather, wear and degradation. A similar product with a more rugged, smoother surface is called high density ...
There were experiments with gluing plywood with phenolic resins, mostly in the form of an alcoholic solution or powder, which, however, did not provide sufficient accuracy of application. Around 1930 a dry process of gluing veneers to plywood with phenolic resin in form of a film has begun to spread in the production of waterproof plywood. [9] [10]
A product resembling hardboard was first made in England in 1898 by hot pressing waste paper. [8] In the 1900s, fiber building board of relatively low density was manufactured in Canada.
Another use of phenolic resins is the making of duroplast, famously used in Trabant automobiles. Phenolic resins are also used for making exterior plywood commonly known as weather and boil proof (WBP) plywood because phenolic resins have no melting point but only a decomposing point in the temperature zone of 220 °C (428 °F) and above.
Characteristic thin dark reddish brown glue joints laminating the plies together of this exterior grade plywood. Resorcinol glue, also known as resorcinol-formaldehyde, is an adhesive combination of resin and hardener that withstands long-term water immersion and has high resistance to ultraviolet light.
