Publication number: 20260078266Abstract: Non or low-intumescent fire-resistant coatings, coating compositions used to form the coatings, and composite articles including the coatings are provided herein. In an embodiment, a non or low-intumescent fire-resistant coating is formed from an aqueous coating composition comprising a polyurethane urea resin, a melamine crosslinker, a silicone resin, and a filler. The non or low-intumescent fire-resistant coating has a thermal conductivity of from about 0.03 W/m-K to about 0.1 W/m-K, as measured using a guarded hot plate apparatus in accordance with ASTM E1530. The coating expands by from about 0.1% to about 10% based on a total volume of the coating, after exposure to a propane flame at a distance of 26 mm from the coating and/or exposure to a temperature of about 1200° C. for a period of at least 10 minutes.Type: ApplicationFiled: August 18, 2025Publication date: March 19, 2026Applicant: AXALTA COATING SYSTEMS IP CO., LLCInventors: Stephen Istivan, Gaurang Bhargava, Delson J. Trindade, Ian Sullivan
