The Center for the Polyurethanes Industry (CPI) prepared this guidance document to provide information to professionals concerning important health and safety aspects when working with isocyanates during spray-on lining applications. Although isocyanates based on MDI (diphenyl methane diisocyanate) and HDI (hexamethylene diisocyanate) commonly are used in truck bed and other types of lining systems, it is not the only material in the system that may be potentially harmful to your health; therefore, it is important to read all the information contained in your supplier’s Safety Data Sheets or SDSs (formally known as Material Safety Data Sheets or MSDSs) for the particular spray-on lining system that you are using. SDSs are the primary sources of extensive and specific information on isocyanates as well as on other spray-on lining system ingredients.
This guidance document is intended to help spray-on lining companies, such as truck bed liner companies, educate its workers about isocyanates and appropriate worker protection related to isocyanates. For supporting information, a complimentary video is available on CPI’s website for additional information about working safely with isocyanates-based spray-on linings. Neither CPI nor its member companies are responsible for worker protection, or worker protection programs, for spray-on lining companies.
