CARDAMINE H 641
CARDAMINE H 641 is one of a series of specially formulated phenalkamine curing agents developed for use with liquid and solid epoxy resins. This grade is solvent free although solution versions are available for ease of handling. CARDAMINE H641 is characterized by tolerant mix ratio, excellent hydrophobic character and subsequent corrosion resistance, good cure at low temperature and under adverse conditions with a high degree of flexibility and toughness.
