INSTRUCTION DESCRIPTION (1) The present invention relates to a liquid fluorenone rubber composition which is hardened by a hydroquinone reaction, and more particularly to a liquid fluorenone rubber of the above type suitable as a film coating on a substrate. The composition, which hardens upon heating for a short time, produces a hardened coating that exhibits good adhesion to the substrate. A basic fabric comprising Synthetic Fiber Synthetic 66 or inorganic fibers such as glass fibers provides a number of advantages when coated with an anthrone rubber composition, including good thermal characteristics, flame retardancy, and excellent storage. Stability. This type of basic fabric has therefore been used in a wide variety of applications, including airbags, particularly automotive airbags. Additional advantages provided by coating an anthrone rubber composition with a material made from a fiberglass braid include improved abrasion resistance, flexibility, and retention. · When coating a basic fabric made of synthetic fiber or glass fiber, an organic solvent such as toluene or mono-toluene is usually used to dilute the anthrone rubber composition to obtain a thin, uniform coating on the base fabric, and to be coated. A strong bond between the layer and the basic fabric. In recent years, in order to meet the industrial demand for solvent-free compositions due to environmental concerns, liquid fluorenone rubber compositions which can be applied without an organic solvent have been proposed.
