| Description | Master Bond EP21TCHT-1 is a two component, thermally conductive, heat resistant, epoxy compound formulated to cure at ambient temperatures or more rapidly at elevated temperatures, with a 100 to 60 mix ratio by weight. EP21TCHT-1 passes NASA outgassing tests. It is a high strength adhesive and Master Bond EP21TCHT-1 is a two component, thermally conductive, heat resistant, epoxy compound formulated to cure at ambient temperatures or more rapidly at elevated temperatures, with a 100 to 60 mix ratio by weight. EP21TCHT-1 passes NASA outgassing tests. It is a high strength adhesive and produces bonds that are both tough and durable. It resists thermal cycling and many chemicals including water, fuels and most organic solvents. It has a service temperature range of 4K up to 400°F. It adheres well to metals, glass, ceramics, rubbers and many plastics. The hardened adhesive exhibits high thermal conductivity and superior electrical insulation. The thermal expansion coefficient is remarkably low. EP21TCHT-1 is widely used in aerospace, electronics, electronic, automotive and chemical industries. As a NASA qualified system, it is ideal for high vacuum type applications, particularly those where elevated temperature cures are not possible. It also passes MIL-STD-810G for fungal resistance, and withstands 1,000 hours at 85°C/85% RH....

It is suitable for cryogenic applications, serviceable down to 4K. | EP33 is a two part, room temperature curing epoxy system featuring high temperature resistance, good dimensional stability and very good chemical resistance. It is easily machinable, radiation resistant, and meets NASA low outgassing specifications. | EP3UF is a one component epoxy that contains thermally conductive fillers with very small particle sizes imparting a low thermal resistance. This low viscosity system has good flow properties and can be applied in bond lines as thin as 10-15 microns. | Master Bond EP41S-6 is a two part epoxy system that meets UL 1203 for Explosion-Proof and Dust-Ignition-Proof Electrical Equipment for Use in Hazardous (Classified) Locations. The core of the UL 1203 test protocol is chemical resistance testing. EP41S-6 can be used in potentially explosive Master Bond EP41S-6 is a two part epoxy system that meets UL 1203 for Explosion-Proof and Dust-Ignition-Proof Electrical Equipment for Use in Hazardous (Classified) Locations. The core of the UL 1203 test protocol is chemical resistance testing. EP41S-6 can be used in potentially explosive environments, as defined in National Electrical Code, NFPA 70 (National Fire Protection Association). EP41S-6 is a thermally stable compound possessing a glass transition temperature of 145-150°C and serviceability from -80°F to +500°F [-62°C to +260°C]. It offers a high dielectric strength of 440 volts/mil at 75°F for a 0.125 inch thickness. This compound features good flow properties making it ideal for sealing and potting applications for electrical feedthroughs across various industries.... Read More |
