What are the Challenges and Restraining Factors of the Chemical Surface Treatment Market?

Manufacturers have a hard time following strict rules like REACH (Registration, Evaluation, Authorization, and Restriction of Chemicals), OSHA, and the Toxic Substances Control Act (TSCA). Many traditional surface treatment chemicals, especially those that contain hexavalent chromium, cadmium, and cyanide compounds, are being banned or phased out because they are bad for the environment and health. This means that businesses have to either change their formulas or buy newer, often more expensive, options.

The chemicals used in surface treatment, like acids, solvents, and specialized compounds, can have their prices go up and down. This is often because of problems with the supply chain or political issues. Also, small and medium-sized businesses (SMEs) have to pay a lot of money to properly dispose of the chemical waste that is made during the treatment process, and they need permission from the government to do so.

When industries start using lighter materials like carbon fiber composites and advanced aluminum/titanium alloys, traditional surface treatments don't always work as well as they should. This means that we need advanced, material-specific chemistries and surface preparation methods that use plasma or lasers, which are costly and require technical know-how.
