Formwork plywood is a board formed by superimposed eucalyptus wood sheets glued together under heat and pressure with phenolic glues. The sheets are glued with the grain perpendicular to the adjacent layers and the outer sheet is usually in different African woods. In this specific case, the faces are coated with phenolic film and all the ends are sealed with epoxy resin, which provides high physical-mechanical resistance, great resistance to water and abrasion.
