Product Overview:
Hong Ye HY-9405 is a premium two-component addition-cure platinum catalyzed blue jelly gel specifically engineered for long-life outdoor waterproof and low-dielectric gel potting of 5G active antenna units, cavity filters, phase shifters and remote radio units. With a buttery soft consistency measured at a penetration of 170 plus or minus 30 (0.1mm) and a durably tacky surface, HY-9405 delivers reliable long-life sealing and protection that outlasts conventional gaskets, foams and caulks by a wide margin. The product is mixed 1:1 by weight, self-levels after pouring, cures at room temperature within 4 to 6 hours, and requires no vacuum degassing, making it a straightforward high-performance gel to deploy on production lines worldwide. As a low viscosity fast flow grade, this variant pours easily into narrow channels and complex cavities, levels quickly with minimal bubbles, and is optimized for automated meter-mix dispensing on high-speed lines. It is engineered for sealing outdoor telecom active antenna units, cavity filters, phase shifters and radio units against rain, condensation and salt fog, combining low dielectric impact on RF performance with weather resistance, thermal stability and field reworkability. (EN) Backed by Hong Ye’s nearly 20 years of silicone manufacturing expertise and supplied to customers in over 60 countries, HY-9405 combines the performance of premium imported gels with the cost efficiency, short lead time and responsive technical support of a Chinese manufacturer. Whether you are running a first sample trial or ramping to full production, Hong Ye delivers consistent batch-to-batch quality, comprehensive documentation and application engineering support from first sample through full production.

Key Features:
• Low viscosity fast flow formulation fills narrow gaps and intricate cavities quickly, self-levels with minimal bubbles and suits automated dispensing.
• Excellent electrical insulation with dielectric strength above 20 kV/mm
• Repairable and reworkable: old gel can be topped up with fresh gel without full removal
• No VOC emissions during or after cure, suitable for enclosed cleanroom and medical environments
• Can be heat-cured at 60-80C for 30-60 minutes to shorten demolding time in mass production
• Resistant to ozone, UV, moisture, salt spray and common cleanroom cleaning agents
• 1:1 mix ratio by weight, easy to meter with manual or automated dispensing equipment
• Compatible with automated meter-mix dispensing equipment for high-volume production lines
• 12 month shelf life when sealed and stored below 25C in dry ventilated conditions
• Third-party test reports including RoHS, REACH, FDA and LFGB available on request
• Self-leveling after pouring, no vacuum degassing required, saving process time and equipment
• Recommended model: HY-9405 - Blue medium tack electronic potting jelly gel
