Copper constitutes over 80% of the composition of antifouling coatings, making it a significant cost driver. The price of copper is known to fluctuate in response to economic conditions, earning it the moniker “Dr. Copper.” In recent times, copper prices have experienced spikes due to supply constraints.
The weight percentage breakdown of the key components in a wet paint for large vessels reveals the substantial presence of cuprous oxide, accounting for over 30% of the paint’s weight.
Given the heavy reliance on copper in antifouling coatings and its impact on overall costs, it becomes crucial to explore alternative approaches that can reduce copper usage without compromising the desired efficacy of the coating. By finding innovative solutions and minimizing dependence on copper, we can mitigate the effects of price fluctuations and create more cost-stable coating options for the industry.
The demand for copper is projected to witness substantial growth in the coming decades, largely driven by the transition towards electrification. This anticipated surge in demand is expected to lead to a significant increase in copper prices.
Reducing the reliance on copper in coatings can bring about several benefits:
By addressing these aspects and exploring alternatives to copper, we can simultaneously enhance cost-effectiveness, ensure price stability, and promote environmental responsibility in the coatings industry.

Taking measures to reduce the usage of cuprous oxide in coatings offers immediate cost savings and long-term benefits, creating a win-win scenario.
By embracing these strategies and exploring alternatives to cuprous oxide, we can simultaneously save costs in the present while securing the industry against future copper demand. This approach ensures both immediate financial benefits and long-term sustainability.
