Overview
ELAZTOBOND® A250 is an excellent resin choice when bonding rubber compounds to nonrubber parts is required. It is used in combination with methylene donors such as hexamethylenetetramine (HMT) or hexamethoxymethylmel amine (HMMM).
ELAZTOBOND® A250 was 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.
