Birch plywood (Riga Ply) bonded with waterproof phenol resin adhesive and overlaid on both the sides with a phenol film (grade F/F).
- Dark brown (167g/m2 and 220g/m2), black (120g/m2) - for concrete shuttering, building boards, transport industry, flooring.
Environmentally friendly, durable, workable, hygienic, not smelling and don't give taste to food-stuff, easy to clean, wear-proof, weather and water-proof, resists commonly used chemicals. Riga Form for shuttering can be re-used many times.
Plywood is glued with waterproof phenol formaldehyde resin adhesive. Bonding is resistant to weather and boiling water. It meets requirements of the following standards:
- EN 314 / 3rd class;
- BS 1203 / H4 (previously WBP);
- DIN 68705 Part 3 / type BFU 100
In accordance with the standard EN 13986 formaldehyde emission meets the Class E1 requirements. Test method EN 717 Part 2.
A smooth phenol film, which is hot-pressed onto the surface, is used as an overlay. The film is composed of a base paper and phenol resin that is impregnated into the base paper. Film weights 120g/m2, ~170g/m2, 220g/m2. Overlaying with higher resistance to abrasion and multi-layer overlaying are also possible (respectively 240g/m2, 440g/m2 etc.). Multi-layer overlaying gives superior wear resistance.
