Resorcinol U.S.P. Flake Benzenediol 108-46-3 Indspec Aminoplaste / Phenoplaste (UF, MUF) ADHESIVE Resorcinol from INDSPEC Chemical Corporation is manufactured by the sulfonation of benzene under conditions that promote disubstitution in the meta position, followed by fusion with anhydrous caustic. The resultant resorcinol is purified under controlled conditions to yield a technical grade product, typically 99.8% pure. INDSPEC also offers a U.S.P. grade of resorcinol which meets the U.S. Pharmacopeia for applications in which ultra-high purity is required such as cosmetics and pharmaceuticals. RESORCINOL APPLICATIONS Resorcinol is the essential component of an adhesive system used in the manufacture of tires for passenger cars, trucks, off-the-road equipment and other fiber reinforced rubber mechanical goods. Adhesives formulated from resorcinol-formaldehyde resins or phenol modified resorcinol-formaldehyde resins are the criteria for wood bonding applications demanding room temperature cure, structural integrity, and waterproof characteristics. Resorcinol is an important chemical intermediate in the manufacture of specialty chemicals, such as light screening agents for the protection of plastics from exposure to ultraviolet light. Other uses for resorcinol include the manufacture of dyestuffs, pharmaceuticals, flame retardants, agricultural chemicals, fungicidal creams and lotions, explosive primers, antioxidants, a chain extender for urethane elastomers, and a treatment to improve mechanical and chemical resistance of paper machine fabrics. Resorcinol. Used in adhesive systems for the manufacture of tires for passenger cars, trucks, off-the-road equipment and other fiber reinforced rubber mechanical goods. Also used for wood bonding applications. Provides room temperature cure, structural integrity, and waterproof characteristics.
