Product Overview
Our Electronic Potting for Solid State Relays is a professional high-transparencySilicone Potting Compound developed for the encapsulation, sealing, insulation and protection of Solid State Relays (SSRs). As a leading manufacturer ofelectronic Potting Compound and silicone raw materials, we optimize the formula for SSRs’ core needs—high light transmittance, thermal stability, insulation and environmental protection. Unlike ordinary potting silicones, it is a solvent-free addition curing silicone with high transparency, excellent fluidity to fill tiny gaps, fast deep curing, no pollution to the environment, and can effectively protect SSR internal components from moisture, dust and corrosion, ensuring stable and reliable operation for procurement partners.
Key Features & Advantages
- High Transparency & Excellent UV Resistance: Cured colloid has 95% light transmittance (450nm, 2mm), ensuring clear observation of SSR internal components without affecting visual inspection; outstanding UV resistance, no yellowing or aging under long-term UV irradiation, maintaining stable performance and appearance, extending the service life of SSRs.
- Solvent-Free & Environmentally Friendly: Adopts high-purity addition curing silicone formula, no solvent added, non-toxic, odorless, pollution-free to the environment and operators, complying with international environmental standards, suitable for high-standard electronic component production and procurement requirements.
- Superior Temperature Resistance & Stability: Can work stably for a long time in the range of -50℃ to 250℃, with excellent high and low temperature resistance, no curing failure, deformation or performance degradation in extreme temperature environments; low thermal expansion coefficient (280 ppm/℃), reducing stress caused by temperature changes, protecting SSR internal circuits.
- Good Fluidity & Fast Deep Curing: Excellent fluidity (viscosity 500±100 mPa.s for both components), can easily fill tiny gaps and fine structures of SSRs, ensuring full encapsulation without dead corners; fast deep curing speed, curing time can be adjusted by changing temperature, improving production efficiency for procurement partners.
- Ultra-High Insulation & Strong Adhesion: Excellent insulation performance (volume resistivity ≥1.0×10¹⁵ Ω·cm), effectively isolating SSR internal circuits, preventing leakage and short circuits; strong adhesion to PC, PMMA, PCB and SSR internal metal components, forming a tight seal, avoiding gaps and ensuring reliable protection.
How to Use (Step-by-Step Guide)
- Pre-Mixing Preparation: Clean and dry the mixing container to avoid impurities affecting curing; fully stir Component A and Component B separately (each is colorless transparent liquid) to ensure uniform consistency, and keep them sealed when not in use to avoid contact with air moisture.
- Mixing: Mix Component A and Component B at a weight ratio of 1:1 (customizable), stir slowly and evenly to avoid generating air bubbles; after mixing, let it stand for defoaming or vacuum degassing to remove air bubbles completely.
- Encapsulation: Clean the solid state relay to be encapsulated, dry it thoroughly (ensure internal components are dry), then pour the mixed potting compound into the SSR casing, making sure it fully infiltrates all components without gaps or overflow.
- Curing: Place the encapsulated SSR into an oven for curing; the curing speed can be adjusted by changing the temperature, and the product can achieve stable performance after full curing, which is suitable for subsequent production processes.
