EP21TDC-2LO Two-Component, Flexible Epoxy Resin
Description
A high-performance bonding, sealing, coating and encapsulation system called EP21TDC-2LO offers high flexibility and excellent toughness. It cures at room temperatures or more rapidly at elevated temperatures. It has a 1 to 3 mix ratio by weight or volume and has a working life of >90 minutes for a 100gm. mass. EP21TDC-2LO is easy to apply. A little exotherm is developed during cure making it suitable for use in thick as well as in thin sectioned configurations.
EP21TDC-2LO meets NASA low outgassing specifications. It exhibits outstanding electrical insulation properties and superior thermal conductivity. It is durable and adheres well to both similar and dissimilar substrates. EP21TDC-2LO has a service operating temperature range of 4K to 250°F. It also features exceptional thermal shock resistance.
EP21TDC-2LO has a Shore D hardness of 36 and an elongation of >50%. It has a tensile strength of 1,070 psi and a T-peel strength of >15 pli. Its tensile shear strength for aluminum to aluminum bonds is >980 psi. Particularly noteworthy is its volume resistivity of >1012 ohm-cm and its thermal conductivity of 9 BTU/in/ft²/hr/°F.
