Pinepanels Formwork MDO Plywood with Arclin™ Readyform 3323 MDO Plywood from Palmasola Brazil is the No.1 high performance panel choice for formwork applications where a matte concrete fair finish is desired. Pinepanels Formwork MDO Plywood with Arclin™ Readyform 3323 concrete form overlay is an MDO which represents the industrial standard in concrete form overlay performance. The reverse of the panel has a 125 gsm dark brown phenolic film which acts as a moisture barrier and can also be used as a formwork surface as any other Film Face Plywood. Using an advanced resin formulation, Pinepanels Formwork MDO Plywood with Arclin™ Readyform 3323 significantly increases performance in engineered wood products for reusable concrete forms.
Pinepanels Formwork MDO Plywood with Arclin™ Readyform 3323 MDO conforms to requirements of the U.S. Product Standard PS1-95 for Construction and Industrial Plywood to provide a smooth surface on engineered wood substrates to allow multiple re-use of panels in concrete pours.
Pinepanels Formwork MDO Plywood with Arclin™ Readyform 3323 MDO Plywood for construction use also meets the European Union Construction Product Directive EN 13986 CE2+ to structural level.
Pinepanels Formwork MDO Plywood with Arclin™ Readyform 3323 is superior to conventional Film Face Plywood
The quality surface of concrete comes from MDO’s ability to mask imperfections and reduce the transfer of the wood grain onto the concrete surface. The result of using a medium density overlay is consistent color and a smooth finish that is ideal for painting or coating. The ability to reuse the MDO panels several times means more pours with each panel significantly lowering labour and material costs and reducing jobsite waste.
More pours than conventional Film Face Plywood.

Meets EUTR standards,
Non-formaldehyde synthetic resin MDI/PMDI is used as binder in OSB 3. However, the natural formaldehyde in the veneer strands do emit formaldehyde but such emission is far below the limits set out in EN 13986.
The thermal conductivity (l) of OSB as determined according to BS EN 12664 Thermal performance of building materials and products. Determination o f thermal resistance by means of guarded hot plate and heat flow meter methods. Dry and moist products of medium and low thermal resistance5 is 0.13 W/m.K for a mean density of 650 kg/m3 as set out in BS EN 13986.
Panel sizes commonly available is 2440mm x 1220mm in thickness 12mm & 18mm. Other dimensions can also be arranged with prior arrangement.
Wood Fibers is a living material and is subject to moisture movement according to surrounding conditions, which affects the flatness and thickness swell of panels. .It is important to condition the panels to reach a moisture content near to the equilibrium of their permanent environment. The recommended stocking conditions are 20°C and a RH of air of about 60%.
Wetting of OSB should be avoided. OSB3 is not waterproof; the term ‘moisture resistant’ applies to the adhesive binder which will not break down in the presence of moisture (within BS EN 300 limits).
Like other wood-based panel products, OSB is hygroscopic and its dimensions change in response to a change in humidity. A change of 1% in moisture content typically increases or decreases the length, width and thickness of the OSB by 1% in dimensions and thickness.
The recommended stocking conditions are 20°C and a RH of air of about 60%. The boards should be stored in their intended installation area for a minimum of 48 hours to acclimatise to the surrounding temperature and humidity. Check for any damages before fitting.
Wetting of OSB must be avoided. OSB3 is not waterproof; the term ‘moisture resistant’ applies to the adhesive binder which will not break down in the presence of moisture (within BS EN 300 limits).
All common woodworking tools can be used successfully with Kronospan OSB 3. As a general rule, cutting speeds should be lower than for conventional wood. Carbide or diamond tipped blades and cutters are recommended because of their longer cutting life.
Boards with straight edges need 2-3 mm dilatation gap at the edges of the boards for possible moisture expansion, depending upon the assessment of risk by the users.
Corrosion resistant fasteners should be used where OSB is part of a load bearing structure. Structural fastening systems are only permitted if their use has been approved by the manufacturer.
Guidance on the use of OSB in load-bearing applications is given in DD CEN/TS 12872.
OSB 3 boards must be free from direct exposure to weather conditions, sun light and rains to prevent from weathering and decay.
Physical wetting of all grades of OSB should be avoided. When wet, OSB will increase appreciably in thickness and start the weathering and decay process.
OSB will not normally be attacked by wood-boring insects common in temperate climates as these are susceptible to fungal attack under prolonged wet conditions.
