Micronized Copper Azole (MCA) is a wood preservative that is widely used to protect wood from rot, decay, and insect damage. It is commonly applied to pressure-treated wood, which is used in a variety of outdoor projects such as decks, fences, and landscaping structures. MCA is composed of copper particles and organic azole compounds, which together create a protective barrier around the wood, helping it to last longer even in harsh outdoor environments.

Micronized Copper Azole – Advantages
The main advantage of MCA-treated wood is its effectiveness in preventing wood decay and insect infestation, which are common problems in outdoor structures. The copper in the treatment acts as a natural biocide, repelling insects like termites and preventing the growth of fungi that cause rot. The azole component enhances the wood’s resistance to mold and other moisture-related damage.
Less Toxic
One of the key benefits of using MCA-treated wood is that it is less toxic than older wood treatments, such as Chromated Copper Arsenate (CCA). MCA is considered environmentally friendly and is safe for use around humans, pets, and plants. This makes it an ideal choice for residential projects like garden beds, decks, and outdoor furniture.
Micronized Copper Azole Plywood
MCA-treated plywood is also available, offering the same protection as treated lumber but with the versatility of plywood. This type of treated plywood can be used for outdoor projects where both moisture resistance and structural integrity are important, such as in sheds, gazebos, or outdoor furniture.
Micronized Copper Azole – A Beautiful Appearance
Another benefit of MCA-treated wood is its appearance. Because the copper particles used in the treatment are micronized, the wood has a lighter, more natural appearance compared to older pressure-treated wood, which often had a greenish tint. This makes it easier to stain or paint to match the aesthetic of your project.
