| Description | LED405Med is a one part, nano-silica filled system that cures upon exposure to a 405 nm LED light. It meets ISO 10993-5 cytotoxicity requirements for use in medical device assembly. The nanosilica filler results in both lower shrinkage upon cure, as well as greater dimensional stability with a LED405Med is a one part, nano-silica filled system that cures upon exposure to a 405 nm LED light. It meets ISO 10993-5 cytotoxicity requirements for use in medical device assembly. The nanosilica filler results in both lower shrinkage upon cure, as well as greater dimensional stability with a coefficient of thermal expansion of 35-40 in/in x 10-6/°C. It provides good toughness, is optically clear with a refractive index of 1.50, and offers excellent light transmission properties. The system can be used for bonding, sealing, coating and small encapsulations involving optical assemblies or other sensitive components....

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.... Read More | EP21TDCS-LO is an electrically conductive, silver-filled epoxy widely used for demanding applications in the electronic, electrical, computer, semiconductor, aerospace and optical industries. It is suitable for cryogenic applications, serviceable down to 4K. | EP41S-5ND Black is a two part, NASA low outgassing rated epoxy, with outstanding chemical resistance to acids, bases, alcohols and fuels. Most significantly it will withstand liquid immersion to harsh chemicals such as methylene chloride, phenol (10%) and nitric acid (30%). | EP51CC is a two component, fast setting epoxy with a color coding system where Part A is white and Part B is black. The two parts combine into a uniform gray color paste, which indicates proper mixing. This fast curing, non-drip compound is ideal for bonding and sealing applications. |
