Medite Moisture Resistant (MR) MDF Datasheet

Medite MR

Medite MR is a moisture resistant MDF panel designed for use in humid conditions in accordance with MDF.H (Option 1) as defined in EN 622-5 so is ideal for applications such as kitchen and bathroom furniture, window and skirting boards and architectural mouldings. Developed at Medite’s world class MDF facility in Clonmel, Medite MR broadens the range of the Medite family of high performance MDF products.

Applications  Medite MR is used as a substitute for softwoods and hardwoods and as a panel product in non-stressed applications. It is successfully used for kitchen furniture, bathroom furniture, architectural mouldings, skirting boards, architraves, window boards, flooring and general interior joinery. Medite MR is suitable for interior humid conditions and is manufactured in accordance with EN 622-5. Medite MR is not suitable for external applications. Medite MR must be sealed, primed and painted on all surfaces prior to installation, especially when placed next to damp plaster. Boards of this type are suitable for use in Hazard Class 1 and 2 environments of EN 335-3 provided an appropriate coating system is used.

Performance The test methods used for moisture resistant Medite MR includes a specialized cyclic test (EN 321) in which test pieces, after conditioning, are immersed in water at 20°C for 72 hours, frozen in air at -12°C for 24 hours, and heated in an air-circulated oven at 70°C for 72 hours. This cycle is carried out three times, followed by post conditioning and physical testing according to EN 622 test methods. Medite MR is accepted in the UK by the NHBC for use in suitable applications.

Appearance Medite MR is distinguishable from other Medite MDF products by its green identification colour.

Conditioning The moisture content of Medite MR is in the range of 7% +/- 2% at the time of manufacture. Changes in dimensions of wood and wood-based sheet materials occur due to changes in relative humidity. For this reason, Medite MR panels should be conditioned to the final environment for two to three days before cutting and fixing.

Machining/finishing  Cut or profiled edges of Medite MR should first be sanded with 150-240 grit, prior to painting. The recommended coating system for the edges is to seal, prime and topcoat with de-nibbing between coats to produce a smooth finish. The desired finish on the face can be achieved by application of a base-coat and top-coat. If water-based coatings are used, it is important that forced drying or quick-drying systems be applied in order to maintain surface quality.



Fire rating Medite MR is expected to achieve a fire class rating of Euro Class D within the European classifications.
