TACTIX® 556

TACTIX® 556 is a low moisture, hydrocarbon epoxy novolac resin. These compounds have a dicyclopentadiene backbone with a low average molecular polarity, a feature critical to low moisture absorption. Indeed, the moisture absorption of TACTIX® 556 is considerably lower than that of typical phenolic novolacs such as ARALDITE® EPN 1139 and ARALDITE® EPN 1138 resins. TACTIX® 556 resin shows exceptional ability to retain properties under conditions of moisture and elevated temperature. Additionally, its outstanding properties come with no sacrifice to processability. Similar to Bis-A epoxy resin, TACTIX® 556 resin can be used with a variety of conventional hardeners to optimize specific properties. TACTIX® 556 resin is ideal for new uses where retention of properties under hot and wet conditions is critical.
