EP30-2: Qualified by Laser Interferometer Gravitational-Wave Observatory (LIGO) for optical assembly applications

Product catalog summary
Introduction
Master Bond EP30-2 epoxy has been qualified for use in critical applications at the Laser Interferometer Gravitational-Wave Observatory (LIGO). This case study highlights its application in bonding prism elements and acoustical dampeners to optical components.
Specifications and Standards
The epoxy is a two-part system mixed and cured according to specific ratios and schedules. It meets NASA/ASTM E-595 standards for low outgassing, crucial for sensitive LIGO applications. Outgassing rates for gases like hydrogen and helium were measured using a Residual Gas Analyzer, showing levels as low as 10-11 Torr-L/s/cm2.
Applications and Impact
The epoxy was used in the twin LIGO detectors, which confirmed a major prediction of Einstein's general theory of relativity by detecting gravitational waves from a black hole merger. This significant scientific achievement underscores the importance of the epoxy's role in the observatory's operations.
References
Key references include news releases and scientific papers detailing the detection of gravitational waves and the role of the epoxy in these findings.

EP30-2: Qualified by Laser Interferometer Gravitational-Wave Observatory (LIGO) for optical assembly applications-2

CASE STUDY EP30-2: Qualified by Laser Interferometer GravitationalWave Observatory for optical assembly applications Master Bond EP30-2 epoxy was qualified for use in critical Laser Interferometer Gravitational-Wave Observatory (LIGO) bonding applications. The main applications involved bonding prism elements, and bonding acoustical dampeners to optical components. The two part epoxy was mixed and cured based on the mix ratio and the cure schedule recommended on the data sheet. The cured product was then validated for its low outgassing properties. The product already met NASA/ASTM E-595 standards...
