Master Bond EP42HT-2AO-1 Two Part, Cryogenically Serviceable Epoxy

Description: Master Bond EP42HT-2AO-1 Black is a room temperature curable, two component epoxy adhesive, sealant, coating and casting material that meets NASA low outgassing specifications. It features high temperature resistance and outstanding chemical resistance and is widely used in a variety of potting and encapsulation applications where thermal conductivity is needed. Aside from being a superior adhesive, sealant and coating, EP42HT-2AO-1 Black is castable to thicknesses exceeding 2-3 inches. EP42HT-2AO-1 Black cures readily at ambient temperatures or more quickly at elevated temperatures even in the presence of moisture. The cured epoxy compound is resistant to various types of chemicals such as inorganic and organic acids, alkalis, many organic solvents, aromatic hydrocarbons, etc. EP42HT-2AO-1 Black is an excellent electrical insulator. Especially noteworthy is its cryogenic serviceability from 4K up to +400°F combined with being relatively impervious to intermittent exposures to steam. Aside from its widespread use in the electronics industry, EP42HT-2AO-1 Black is also used in medical, fiber-optic, optical, as well as OEM type applications. While the mixed material is black in color, Part A is black and Part B is brown.Product Advantages:Non-critical 100:40 mix ratio by weightConvenient cure schedules at both ambient and elevated temperaturesExcellent chemical resistance to acids, alkalis and many solventsCastable to thicknesses exceeding 2-3 inchesExcellent flow propertiesKey Features and Benefits:Passes NASA low outgassing specificationsOutstanding thermal conductivity and electrical insulation propertiesSuperior thermal stability with serviceability up to +400°FSuitable for cryogenic applications at temperatures down to 4K
