WebEP29LPSP requires gelling the mixed epoxy at room temperature, followed by alternative lower elevated temperature cure cycles (8-10 hours at 130-150°F) or (5-7 hours at 175°F) or (3-5 hours at 200°F). EP29LPSP is widely used in applications requiring cryogenic service, optical clarity and NASA low outgassing properties. Product Advantages http://www.vacuumcursus.nl/casussen/outgas_rev.htm

WebMay 8, 2024 · Heat, sunlight, and time can cause these trapped gas bubbles to expand and blow microscopic holes in the surface of the plastic, releasing the gas—outgassing. New glues, finishes, and laminating polymers can also contain gases trapped microscopically within the material. Whatever the form of the material, those gases will slowly escape into ... Outgassing (sometimes called offgassing, particularly when in reference to indoor air quality) is the release of a gas that was dissolved, trapped, frozen, or absorbed in some material. Outgassing can include sublimation and evaporation (which are phase transitions of a substance into a gas), as well as … See more Outgassing is a challenge to creating and maintaining clean high-vacuum environments. NASA and ESA maintain lists of materials with low-outgassing properties suitable for use in spacecraft, as outgassing … See more Outgassing can be significant if it collects in a closed environment where air is stagnant or recirculated. For example, new car smell consists of outgassed chemicals released by heat in a closed automobile. Even a nearly odorless material such as wood may build up a … See more • Outgassing Data for Selecting Spacecraft Materials Online (NASA database) • ESA Outgassing Data for Spacecraft Materials according to ECSS-Q-70-02 See more Outgassing is a possible source of many tenuous atmospheres of terrestrial planets or moons. Many materials are volatile relative to the extreme vacuum of outer space, … See more The outgassing of small pockets of air near the surface of setting concrete can lead to permanent holes in the structure (called bugholes) that may compromise its structural integrity.
