Demand for specialty biocides in the US is forecast to rise 4.0 percent per year to $3.9 billion in 2018. A construction rebound will benefit the wood preservation and paint and coatings markets, while consumer spending and manufacturing gains will support uses in manufactured goods. Nitrogen compounds and organosulfurs will be the fastest growing types. This study analyzes the $3.1 billion US biocide industry. It presents historical demand data for 2003, 2008 and 2013, and forecasts for 2018 and 2023 by product (e.g., halogen compounds, metallic compounds, phenolic compounds, nitrogen compounds, organosulfurs, organic acids, glutaraldehyde), function (e.g., preservative and additive, water treatment, processing) and market (e.g., industrial, consumer and commercial, energy). The study also considers market environment factors, details industry structure, evaluates company market share and profiles 32 industry competitors, including Dow Chemical, Lonza Group and Ecolab.
