Packing Info Data Sheet

01. Application

Dongwha Moisture Resistance MDF is an ideal substrate for kitchen and bathroom cabinetry and any other areas where moisture and high humidity is present.

Its main characteristic produced from melamine resin system is an increased in dimensional stability or lower thickness swelling where there is the risk of occasional wetting or prolonged exposure to high levels of humidity. There is an option of having green dye added on to the board. This is upon request by customer.
