HONG YE SILICONE Transparent Electronic Potting Silicone for Low Temperature Cofired Ceramics (LTCC) is a high-performance two-component Addition Curing Silicone, also known as Silicone Encapsulant and Electronic Potting Compound, tailored for LTCC protection. Crafted from high-purity Silicone raw materials, it features a 1:1 weight mixing ratio, high transparency (95% transmittance at 450nm), excellent UV resistance and wide temperature adaptability (-50℃ to 250℃). It cures quickly, fills fine gaps of LTCC, ensures insulation and light transmission, complies with EU RoHS, and supports full parameter customization (around 198 characters).
Product Overview
Our Transparent Electronic Potting Silicone is specially developed for Low Temperature Cofired Ceramics (LTCC), dedicated to encapsulating, sealing, insulating and light-transmitting protection of LTCC substrates, circuits and components. As a leading manufacturer of liquid silicone and addition curing silicone, we optimize the formula for LTCC’s high-precision, fine-structure and light-transmission needs, enhancing high transparency, good fluidity and fast deep curing performance. Compared with epoxy potting resin, it is solvent-free, non-polluting, has high elasticity and excellent UV resistance, avoiding LTCC material damage and light loss.
Key Features & Advantages
- High Transparency & Light Transmission: 95% transmittance at 450nm (2mm thickness), refractive index 1.41, ensuring excellent light transmission performance of LTCC components; no yellowing or light loss after long-term use, maintaining LTCC’s optical stability.
- Environmentally Friendly & Gentle Curing: It is an addition curing silicone, solvent-free, non-toxic and pollution-free, complying with environmental protection requirements; fast deep curing, good fluidity, easily filling fine gaps of LTCC structures, ensuring full encapsulation without dead angles.
- Excellent Temperature & UV Stability: Stable performance in a wide temperature range (-50℃ to 250℃), suitable for LTCC’s high-temperature working scenarios; outstanding UV resistance, resisting aging and yellowing under long-term UV irradiation, extending LTCC service life.
- Superior Insulation & High Elasticity: High volume resistivity (≥1.0×10¹⁵ Ω·cm), ensuring reliable insulation of LTCC circuits; curing into a high-elastic rubber, with good impact resistance, avoiding LTCC substrate damage caused by thermal stress or mechanical impact.
- Easy Operation & Customizability: 1:1 weight mixing ratio, simple to operate; optional vacuum defoaming or static defoaming, improving encapsulation efficiency; as a professional Silicone Potting Compound manufacturer, we customize viscosity, hardness and operating time to match different LTCC specifications.
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 eliminate air bubbles, ensuring no bubbles affect LTCC encapsulation and light transmission.
- Component Preparation: Clean the LTCC components to be encapsulated thoroughly, dry them (ensure LTCC substrates and chips are dry before encapsulation), then pour the mixed glue onto the components to ensure full infiltration.
- Curing: Place the encapsulated LTCC components in an oven for curing; adjust the curing speed by changing the temperature, and ensure full curing to achieve optimal light transmission and insulation performance.
