Silicone RTV
产品描述
Product Description
SS-25是一种具有导电能力的、在湿度条件下硫化的单组分室温硫化硅橡胶。连接件在1小时内即可用手拿取。固化后的弹性体可抵御气候、臭氧、潮湿、紫外线及高温。SS-25适用于手工操作及自动设备。
SS-25 is an electrically conductive, moisture curing silicone RTV. SS-25 is a 1-Part silicone that when applied to the substrate allows handling of the assembly within an hour. When cured, the elastomer resists weathering, ozone, moisture, UV and high temperature. SS-25 works well in manual and automatic dispensing equipment.

使用限制
Limitations
待固化后再使用工件。确保施用面内有足够剂量以达到效果。
Allow to fully cure before putting assembly into service. Ensure enough product remains between flanges to be effective in an assembly.
关于固化
Curing
提高湿度和温度有利于大幅缩短固化时间。通常在开放空间下施用后露置于环境湿度下固化即可形成导电性能。
Cure speed can be accelerated with increased humidity and heat to very rapid cure times. Typical utilization involves dispensing in open air and after exposure to ambient humidity; a room temperature cured rubber with electrically conductive properties is formed.
