Cymel 481 Methylated melamine-formaldehyde Cytec Aminoplaste / Phenoplaste (UF, MUF) >> Melamine formaldehyde, MF ADHESIVE >> Water-based CYMEL 481 is a high solids aqueous solution of a methylated melamine-formaldehyde resin having exceptionally fast catalyzed cure response. This resin is infinitely dilutable in cold water. This feature, combined with fast cure, makes it most suitable for many binder applications. CYMEL 481 resin is suggested for any binder application requiring a fully water-soluble thermosetting melamine resin. It is also recommended to modify other watersoluble or dispersible resins to promote water resistance, hardness, and punkproof properties, such as phenolics for fiber glass insulation. It can be used to impregnate various synthetic and natural fibers for filter cartridges and cooling tower fins and as a sizing agent for cementasbestos board. High solids aqueous solution of a methylated melamine-formaldehyde resin. Possesses a very fast catalyzed cure response. Suits for many binder applications. Modifies other water-soluble or dispersible resins. Promotes water-resistance, hardness and punkproof properties. Impregnates and laminates various synthetic and natural fibers.
