Product Overview
Our High Transparency Electronic Potting Compound is specially developed for Scanning Tunneling Microscopes, dedicated to encapsulating, sealing, insulating and protecting STM probe modules, control boards, precision chips and signal transmission components. As a leading manufacturer of liquid silicone and addition curing silicone, we optimize the formula for ultra-high-precision STM observation scenarios, enhancing transparency, insulation and low signal interference to adapt to the harsh precision requirements of STMs. Compared with epoxy potting resin, it has excellent UV resistance, no yellowing, low shrinkage, and ensures clear observation of STM internal components without affecting detection accuracy.
Key Features & Advantages
- Ultra-High Transparency: Transmittance up to 95% (450nm, 2mm), refractive index 1.41, high clarity after curing, allowing visual inspection of STM internal components without blocking observation or interfering with detection precision.
- Environmentally Friendly & Safe: Addition-curing formula, solvent-free and non-toxic, no harmful emissions during curing, pollution-free to the environment and STM precision components, meeting international environmental standards.
- Superior Temperature Adaptability & UV Resistance: Stable performance from -50℃ to 250℃, withstanding extreme temperature fluctuations in laboratory environments; excellent UV resistance, no yellowing or aging after long-term use, maintaining transparency and performance stability.
- Excellent Fluidity & Rapid Curing: Low viscosity (500±100 mPa.s), good fluidity, capable of filling tiny gaps of STM precision components; can be cured by adjusting temperature, realizing rapid deep curing and improving production efficiency.
- Strong Insulation & Customizability: High volume resistivity (1.0×10¹⁵ Ω·cm), excellent insulation performance, isolating static and signal interference; as a professional Silicone Potting Compound manufacturer, we customize hardness, viscosity, transmittance and curing speed to match different STM models.
How to Use
- Pre-Mix Preparation: Mix Component A and Component B in a dry container, stir evenly, then let stand to defoam or remove bubbles by vacuum pumping, avoiding air bubbles that affect transparency and insulation.
- Component Preparation: Clean the STM components to be encapsulated thoroughly, dry them completely (ensure the surface of precision parts is dry to avoid affecting adhesion and curing effect), then pour the mixed adhesive to fully infiltrate the components.
- Curing: Place the encapsulated components in an oven for curing; adjust the curing speed by changing the temperature—higher temperature shortens curing time, ensuring full curing without affecting component precision.
