RR1112 – Summary of evidence – solvent-based hydrophobic coatings and risks for acute respiratory toxicity
Water repellent coatings are increasingly used by different industries to reduce water and dirt sticking to surfaces. The coatings can be applied by processes that minimise the risk that operators inhale the product but there is evidence that some products are applied by spraying, creating an inhalable mist.
This review examined evidence about these coatings and whether lung disease occurs when applied by spraying. Scientific studies on the hazardous properties of these products, and clinical studies reporting lung disease in people using them, were considered.
