#Interesting Fact : Why Is Moisture Resistant Board Green Colour?

Updated: Apr 10, 2019

Standard Chipboard vs Moisture Resistant Chipboard

Moisture resistant boards are boards with water repellent additives in its core, and is generally indicated by a green colouration. The green coloration is actually green dye used to differentiate standard boards and moisture resistant boards, so the Green Colour Intensity does not signify the concentration of water repellent additives.

What is in the glue?

The normal glue used in particle board and fibreboard are called Urea-Formaldehyde (UF). In moisture resistant boards, melamine is added to UF glue, known as Melamine Urea Formaldehyde (MUF), making it moisture resistant. In some countries, notably in Europe, they have a different standard formula of resin known as V313. But MUF is the general standard in Malaysia. 

Curiously, although the resins used in both moisture resistant Chipboard and MDF are the same, probably because of the history of the products themselves, moisture resistant chipboard and MDF have different common names. Moisture Resistant Chipboard are generally called MUF Chipboard; while for moisture resistant MDF are generally called MR MDF or HMR (High Moisture Resistant) MDF. Different factories have slightly different specifications for their boards, so as a furniture manufacturer, it’s always a good idea to get a specification sheets with all the technical data for the boards you are using for your furniture.

Warning !

Moisture resistant boards are not meant to be “waterproof”. It will not have serious protection against flooding or a plumbing leak.
