【Product Introduction】
CCA wood preservative is one of the most effective and widely used water-soluble preservatives in the world. It is composed of copper, chromium and arsenic compounds. Wood treated with CCA wood preservative can extend its service life by more than 5-10 times even in harsh environments. Its active substances can be adsorbed in the cell wall of wood for a long time, and have strong insect-proof, moth-proof and anti-corrosion effects on wood.
【Functional characteristics】
CCA wood preservative is a brown concentrated liquid that dissolves in water. It has a strong killing effect on fungi and insects, low toxicity to humans and animals, strong penetration into wood, and strong anti-loss ability. The surface of wood treated with this agent is light green, does not affect the paint, does not reduce the strength of wood, does not reduce the insulation of wood, slightly increases the hardness, and enhances the flame retardancy of wood.
【Main ingredients】
Copper (CuO), hexavalent chromium (CrO3), arsenic (As2O5), etc.

[Scope of application]
Logs, construction wood, decorative materials (wood floors, wall assemblies and ceiling keels and plywood), gardening wood products, mining wood, railway sleepers, electric poles, shipbuilding materials, dock planks and sea piles, wooden cooling towers, etc.
[Usage]
1. Brushing treatment: based on the full absorption of the wood surface (completely wet), it is recommended to dilute with water at a ratio of 1:15 and brush 2-3 times.
2. Soaking treatment: based on the complete coverage of the wood surface by the water surface, it is recommended to dilute with water at a ratio of 1:20, and the soaking treatment time is 4-24 hours.
3. Vacuum pressurization method: It is recommended to use a concentration of 2%-3% for vacuum pressurization treatment.
