According to GlobalData’s company profile on Compagnie de Saint-Gobain, Heater-integrated de-icing windows was a key innovation area identified from patents. Compagnie de Saint-Gobain's grant share as of January 2024 was 58%. Grant share is based on the ratio of number of grants to total number of patents.
The patent application (Publication Number: US20240034835A1) discloses a thermosetting binder composition for use in manufacturing products based on mineral or organic fibers. The composition includes water and a water-soluble oligomer ester derived from carbohydrates, diols, and polycarboxylic acids. The solid matter content of the binder composition ranges from 40% to 70% by weight, with the oligomer ester constituting at least 70% of the solid matter. The ratio of hydroxyl groups in diols to the total hydroxyl groups in diols and carbohydrates falls between 5% and 50%, ensuring the desired thermosetting properties.
Furthermore, the method outlined in the patent involves preparing a sizing composition by diluting the thermosetting binder composition with water, applying it to mineral or organic fibers, forming an assembly, and curing the composition through heating. The composition's components, including reducing sugars, hydrogenated sugars, and polycarboxylic acids, contribute to the binding properties necessary for the manufacturing process. The patent also specifies the types of diols, sugars, and acids to be used, along with the acceptable ratios and limits for certain components like free sorbitol. Overall, the patent aims to provide a detailed and precise formulation for a thermosetting binder composition suitable for bonding mineral or organic fibers in various industrial applications.
