Description

Chromated Copper Arsenate is a highly effective wood preservative formulation that protects against decay fungi, wood-boring insects, and termites. Its primary value lies in providing long-term structural integrity for wood used in demanding outdoor and industrial environments. This product is essential for industries involved in utility poles, marine pilings, railroad ties, and construction lumber, where durability and resistance to biological degradation are critical.

Application

• Pressure Treatment of Utility Poles and Crossarms: Provides decades of protection against rot and insect damage for electrical and telecommunications infrastructure.
• Marine and Freshwater Piling Preservation: Used to treat wood for docks, seawalls, and bridge supports, offering resistance to marine borers and fungal decay.
• Railroad Tie and Timber Treatment: Ensures the longevity and safety of railway sleepers and switching timbers exposed to harsh weather and soil contact.
• Construction Lumber for Agricultural and Industrial Use: Protects posts, beams, and fencing used in farms, warehouses, and other industrial settings.
• Cooling Tower Wood Treatment: Preserves the structural wood in cooling towers, which is constantly exposed to moisture and warm temperatures ideal for microbial growth.
• Landscape and Outdoor Structural Timbers: Used for retaining walls, playground structures, and boardwalks where ground contact is unavoidable.

Quality Control

Our Chromated Copper Arsenate is manufactured under strict process controls to ensure batch-to-batch consistency and efficacy. Quality is verified against industry-standard specifications for wood preservative formulations, including analysis of active component ratios (CrO3, CuO, As2O5). Certificates of Analysis (COA) detailing assay, solubility, and stability are available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from incompatible materials. As a strong oxidizer, keep away from combustible materials, reducing agents, and acids. The storage area should be dedicated to chemicals and clearly labeled.
