About Tricoya® Panel

Tricoya ExDF was developed by challenging the most fundamental reason for wood swelling: water absorption onto hygroscopic wood fibres due to the presence of hydroxyl groups. The hydroxyl groups (water loving sites) can bind or release water molecules causing wood to swell or shrink.

Acetylation is a revolutionary sustainable process which increases the number of naturally occurring hydrophobic acetyl groups in the wood cells using acetic anhydride. The process exchanges the hydroxyl groups (chemical formula: -OH) with acetyl groups (chemical formula: -COCH3) preventing water absorption at these sites, and thus enhancing the dimensional stability and durability of the wood.

Tricoya EXDF is suitable for a wide range of exterior applications such as cladding, façade panelling, trim and fascia’s.
