ELAZTOBOND® A250 is an excellent resin choice when the bonding of rubber compounds to non-rubber parts is required. It is used in combination with methylene donors such as hexamethylenetetramine (HMT) or hexamethoxymethylmel amine (HMMM).
ELAZTOBOND® A250 is developed with less than 0.5% free resorcinol to provide a safe alternative to bonding systems that are based on neat resorcinol and traditional resorcinol-formaldehyde polymers.
