双组份缩合电子灌封胶

一、产品特性：
1. 常温即可深层固化；
2. 硫化时发热小，硫化后具有突出的防潮性，防霉性，良好的耐高低温性能（—80℃至+200℃）及适当的硬度；
3. 硫化时不放出任何毒气体；
4. 硫化制品具有良好的弹性，有很好的可修补性能。
二、 典型性能指标
项  目 指  标
外 观（可调整） A为半透明或白色；B为黑色
粘 度   mPa..s 2000—500000（可调整）
组分配料比  A:B 10：1（1：1）
操作时间   h 1-6（可调整）
硫化时间   h,25℃ <24（可调整）
硫化时间   h,60℃ 0.5（可调整）
三、*有多种颜色可供选择：粘度、硫化时间等指标可按用户要求调整：可提供导热、阻燃产品。
四．使用说明
1．清洁表面：用适当的溶剂例如酒精、二甲苯等清洁被粘或被涂覆表面。
2．施胶：按配比称量两组份放入混合罐内搅拌混合均匀, 将混合好的胶料涂敷于需密
封的器件内，一般可不抽真空脱泡，若需得到高导热性，建议真空脱泡后再灌注。
3．固化：室温或加热固化均可。
4．注意事项：胶料应密封贮存。混合好的胶料应一次用完。长时间存放后，胶中的填料会有所沉降，请搅拌均匀后使用，不影响性能。
5．胶液接触有机锡化合物及含有有机锡的硅橡胶，硫磺、硫化物及含硫的橡胶材料，胺类化合物及含胺的材料会发生不固化的现象。在使用过程中，请注意避免与以上物质接触。
五、注意事项
表面或裂缝处最好先用打底剂打底处理，以增强粘结性，防止开裂。
