HONG YE SILICONE Electronic Potting Silicone for Atmospheric Entry Probes is a space-grade two-component Addition Curing Silicone, also known as High transparency mold silicone and Silicone Encapsulant, tailored for atmospheric entry probe equipment. Crafted from high-purity Silicone raw materials, it features 1:1 weight mixing ratio, high transmittance (95% at 450nm), excellent high-temperature resistance (-50-250℃), and good fluidity. It cures deeply quickly, with strong adhesion to precision components, protecting core probe parts from thermal shock and radiation, supporting full parameter customization to meet global aerospace equipment procurement demands (around 195 characters).
Product Overview
Our Electronic Potting Silicone is specially developed for atmospheric entry probes, dedicated to encapsulating, sealing and protecting their core electronic components, optical detection modules, signal transmitters and PCB boards. As a leading manufacturer of liquid silicone and addition curing silicone, we optimize the formula for extreme atmospheric entry scenarios, enhancing high-temperature impact resistance and UV resistance to adapt to harsh conditions like high-speed friction heating, intense radiation and pressure changes. Compared with epoxy potting resin, it has better transparency, flexibility and thermal stability, supports fast deep curing, and ensures long-term reliable protection for probe components, reducing space mission failure risks for aerospace manufacturers.
Key Features & Advantages
- Superior High Transparency: Transmittance up to 95% at 450nm (2mm thickness), refractive index 1.41, ensuring unobstructed light transmission for probe optical detection modules, guaranteeing accurate data collection during atmospheric entry.
- Extreme Temperature Resistance: Operates stably from -50℃ to 250℃, withstanding sudden thermal shock caused by high-speed atmospheric entry friction, avoiding material deformation or performance degradation.
- Excellent Fluidity & Fast Deep Curing: Low viscosity (500±100 mPa.s for both components), good fluidity, able to penetrate tiny gaps of probe components; cures deeply quickly, improving production efficiency of probe manufacturing.
- Environmental & Radiation Resistance: Solvent-free addition-curing formula, non-polluting; excellent UV and cosmic radiation resistance, avoiding material aging in harsh space and atmospheric environments.
- Flexible Curing & Customizability: 1:1 weight mixing ratio, easy to operate; curing speed adjustable by temperature; as a professional Silicone Potting Compound manufacturer, we customize hardness, viscosity and operation time to match different atmospheric entry probe models.
How to Use
- Pre-Mix Preparation: Mix Component A and Component B in a dry container, stir evenly, then let stand for defoaming or vacuum degassing to remove air bubbles, ensuring no bubbles affect encapsulation effect.
- Component Preparation: Clean the probe components to be encapsulated thoroughly, dry them completely (ensure no moisture remains on precision parts), then pour the mixed adhesive to fully infiltrate the components.
- Curing: Place the encapsulated components into an oven for curing; adjust curing speed by changing temperature—higher temperature accelerates curing, ensuring full curing to achieve optimal protection performance.
