Heliofold supplies two silicone adhesives engineered for spacecraft solar-cell protection stacks: DPA-8800 for structural bonding and sealing, and GPA-8811 for transparent cover-glass-to-cell bonding.

Both are built to hold up under the conditions that matter in orbit: thermal cycling, radiation and UV exposure, and the long-duration reliability a bond line can't afford to lose mid-mission.

Both are two-component systems with real cure-process discipline: precise mixing ratios, controlled pot life, and cure windows that must be respected to reach full bond strength.
