Tra-Con Tra-Bond Ablebond 933-1.5 Moisture Resistant Encapsulant
Categories:	Polymer; Thermoset; Epoxy; Filled/Reinforced Thermoset
Material Notes:	TRA-BOND 933-1.5 electrically insulating epoxy encapsulant is formulated to provide a smooth crown over the device of wire bonds. This encapsulant provides protection from thermal and mechanical shock. The long work life and smooth consistency of TRA-BOND 933-1.5 encapsulant make it ideal for use in automatic dispensers. This compound is stable at room temperature for up to three (3) months; however since the filler may settle, we recommend storage at -40°C or colder. Information provided by Tra-Con Inc.
