【使用工艺与注意事项】
搅拌混合:混合前将 A、B 胶分别搅拌均匀,按 1:1 重量比配比,误差勿超过 3% 以免影响固化性能。
灌注脱泡:将混合胶料灌入器件,一般可不抽真空。若需极高导热性,建议真空脱泡后再灌注。
固化条件:冬季室温固化慢,建议采用 80°C 加热固化 (20 分钟),室温则需约 8 小时。
环境影响:环境温度较高时,混合后的操作适用期会相对缩短。
Thermal Conductive Silicone Encapsulant: Premium Solution for Electronic Protection
The H-GF-GY Thermal Conductive Encapsulant is a high thermal conductivity, flame-retardant, two-component addition-cure silicone. It can be cured at room temperature or accelerated by heat. Its flexibility and elasticity allow it to cover uneven surfaces, conducting heat from PCB components to the outer casing, thereby significantly improving the efficiency and service life of high-power devices.
[Why Choose Our Silicone Encapsulant?]
High Thermal Efficiency: Fast heat transfer ensures rapid cooling of sensitive electronic devices.
Process Flexibility: Self-adhesive properties eliminate the need for primers; cured material can be pried open for easy component repair.
Robust Protection: Features excellent insulation, waterproofing, and weather resistance against extreme temperatures and aging.
Certified Safety: Complies with UL 94 V-0 flame retardancy for maximum safety standards.
