NASA Low Outgassing Verification: ASTM E-595 Standards
We qualify every NASA low-outgassing epoxy formulation against the industry-standard thermal vacuum test before it reaches your programme.
Our systems are tested at 125°C and below 5×10⁻⁵ torr (7×10⁻³ Pa) for 24 hours, with full reporting on both required metrics. This is the verification standard agencies and OEMs require for flight qualification.
Beyond the baseline pass criteria, our formulations also deliver:
- Total Mass Loss (TML) below 0.5%, against a 1.00% pass threshold
- Collected Volatile Condensable Material (CVCM) below 0.05% against a 0.10% pass threshold
- Contamination margin suited to long-duration GEO and deep-space missions
- Test data compatible with NASA MAPTIS and OEM qualification submissions
- Verified Contamination Margin
Trusted across optical, avionics, and structural space applications, our ASTM E-595-certified epoxy systems give your programme a verified contamination margin.
- Submission-Ready Documentation
Available with full third-party test reports on request, our outgassing-qualified systems support qualification submissions without additional testing delays on your end.
- Matched to Your Tolerance
With proven outgassing performance across one and two-component chemistries, we deliver low-outgassing formulations tailored to your mission’s contamination tolerance. Our team can help you confirm the right TML and CVCM margin for your application.
The Physics of Space Environments: Vacuum Stability and Outgassing
At Kohesi Bond, we specialise in space-grade epoxy systems engineered to eliminate molecular contamination risk in vacuum and zero-gravity environments. Our formulations are designed to deliver vacuum stability, minimal volatile release, and dimensional consistency across extreme thermal swings. This is everything needed for precise, contamination-free aerospace bonding and encapsulation on a spacecraft.
Beyond the basics, our space-grade epoxies also address:
- Molecular outgassing suppression at pressures down to 10⁻⁸ Torr
- Stable performance across surface temperatures from -120°C to +150°C
- Prevention of condensable film deposition on optics, sensors, and solar cells
- Pre-bake compatible formulations available for accelerated volatile removal
Trusted across satellite, spacecraft, and deep-space mission programmes, our low-outgassing systems protect mission-critical optical, electronic, and structural assemblies where contamination cannot be remedied once the spacecraft is in orbit.
Our custom-formulated epoxy systems are available across one-component and two-component formats for manual or automated dispensing, ensuring consistent outgassing performance batch to batch. Speciality grades meet ASTM E-595, NASA MAPTIS, and agency-specific qualification standards.
With proven formulation expertise, we deliver epoxy for aerospace and space applications tailored to your mission’s contamination budget. Our team can help you find the right low-outgassing system for your platform.

Space-Qualified Application Frameworks
Our low-outgassing epoxy systems support three mission-critical domains in satellite and spacecraft programmes, each engineered against
distinct mechanical, thermal, and contamination requirements.
Our space-grade epoxy formulations protect imaging sensors, telescope optics, and laser communication terminals from condensable contamination, with CVCM below 0.05% and shrinkage under 0.5% to maintain optical registration.
Our satellite potting compound systems encapsulate flight control processors and communication electronics against thermal cycling, launch vibration exceeding 14 g RMS, and total ionising dose radiation up to 100 krad(Si).
Our cryogenic epoxy formulations retain fracture toughness and adhesion at -196°C and below, supporting liquid oxygen fuel systems without cracking under repeated thermal cycling.

Frequently Asked Questions
Our space-grade epoxy systems pass ASTM E-595 with third-party verified TML and CVCM data. Every formulation ships with conditioned mechanical data across the full mission temperature range, ready for agency or OEM qualification submission.
Unverified adhesives release condensable volatiles in vacuum that deposit on optics, solar cells, and thermal coatings, causing damage that cannot be corrected once in orbit. Our NASA low-outgassing epoxy formulations are verified specifically on CVCM, the metric that predicts real contamination risk.
Our epoxy for aerospace and space systems is radiation-characterised for mechanical retention after total ionising dose exposure relevant to your target orbit. This lets your team apply accurate knockdown factors to bond line allowables across the full mission duration.
