EC-M22T-1 is a thixotropic, premixed and frozen, high temperature adhesive specially designed as an epoxy dam material for electronic assembly in dam-and-fill encapsulation. An epoxy dam makes an open barrier, or dam. Either cured or uncured, it can be filled using another epoxy or liquid adhesive. Dam-and-fill encapsulation is generally used to protect small dies or wires.
EC-M22T-1 is an engineered damming epoxy as a flow control barrier around areas of bare chip encapsulation. EC-M22T is ideal for applications requiring a taller, narrower dam. It also has very low ion content, a key feature in microelectronics. EC-M22T cures quickly with heat and is available in premixed and frozen syringes.
