五、使用说明：

1.按配比将A、B组份混合并搅拌均匀。

2.将混合胶料注入需灌封的器件内，一般不需抽真空脱泡，如需得到高导热性，建议真空脱泡后再灌注。

3.室温或加热固化均可。胶的固化时间与固化温度成反比关系。冬季需较长时间固化，建议采用加热方式：80～100℃固化10～30分钟。室温25℃时一般需5小时左右固化。

4.8213属非危险品，但勿入口和眼。

六、注意事项:

1.密封贮存，混合好的胶料应一次性用完。※施胶过程中，导热介面应填充密实，避免产生空隙。

2. 若长期存放，胶液中的填料可能会有部分沉降，请在使用前务必将胶液搅拌均匀。

3.接触以下化学物质会使8213L胶液不固化：.有机锡化合物及含有机锡的硅橡胶材料

硫磺、硫化物以及含硫的橡胶等材料    胺类化合物以及含胺的材料

七、贮存方式：

包装：50Kg/套   

储存：存放于阴凉（26℃ 以下）干燥处，保质期 6个月。
