Gluing classes Plywood is glued with waterproof phenol formaldehyde resin adhesive. The weather and boiling water resistant bonding meets the requirements of the following standards: rd EN 314 / 3 class; BS 1203 / H 4 (previously WBP); DIN 68705 Part 3 / type BFU 100. Formaldehyde emission In accordance with the standard EN 13986 the formaldehyde emission meets the Class E1 requirements (test method EN 717 Part 2). Plywood glued with phenol-formaldehyde resins meets the CARB Phase 2 and Japanese 4-Star Regulation’s requirements. Overlaying A smooth phenol or an UV resistant film, which is hot-pressed onto the surface, is used as an overlay. The phenol film is composed of a basic paper which is impregnated with phenol resin. The UV resistant film is impregnated with a special thermosetting mixture of polymers containing amino resins. Overlaying with higher resistance
