Profill is a two component, one-to-one by volume, no-mix, self-adhering, seamless spray applied open-cell polyurethane insulation system. Profill has been formulated with water as the blowing agent and does not contain CFC, HCFC, HFC or formaldehyde. Profill is suitable for use in Type I, II, III, IV & V construction. Polyurethane products manufactured or produced from this liquid system may present a serious fire hazard if improperly used or allowed to remain exposed or unprotected. The character and magnitude of any such hazard will depend on a broad range of factors, which are controlled and influenced by the manufacturing and production process, by the mode of application or installation and by the function and usage of the particular product. Any flammability rating contained in this literature is not intended to reflect hazards presented by this or any other material under actual fire conditions. These ratings are used solely to measure and describe the product’s response to heat and flame under controlled laboratory conditions. Each person, firm or corporation engaged in the manufacture, production, application, installation or use of any polyurethane product should carefully determine whether there is a potential fire hazard associated with such product in a specific usage, and utilize all appropriate precautionary and safety measures.
