环氧树脂用于高湿环境中的TEM密封保护。尽管RTV硅胶密封已经具备有效防潮功能,但是在一些防潮要求非常严格的使用条件下,环氧树脂密封却能提供更好的密封保护。为了开发出最有效的密封树脂,Ferrotec对多种型号的树脂进行了精心试验和筛选。脆性是树脂用于TEM密封时普遍存在的问题。随着时间的推移,树脂的脆性导致树脂和基板分离,最终导致密封失效。Ferrotec的密封树脂在固化后既具有和基板牢固的结合力,又保持了良好的弹性,因此,能克服上述的弱点。在更具挑战性的热循环试验中,Ferrotec树脂密封同样表现出了优异的防潮性能。这种树脂的电阻值很高,在兆欧级范围。树脂密封产品的最高使用温度推荐为80℃。Ferrotec的密封树脂可用于几乎所有型号的TEM产品。环氧树脂对冷却性能的影响取决于组件的设计。
Epoxy sealing is offered for protecting TEMs used in high humidity environments. Although RTV silicone
sealing has been demonstrated to be an effective moisture barrier, our epoxy sealant offers greater
moisture resistance for those applications requiring the highest protection. Ferrotec has carefully
screened and tested many epoxy types to develop the most effective solution for TEMs. Brittleness is a
common problem with some epoxies used to seal TEMs, and it can lead to separation from the substrate
over time and cause loss of seal. Ferrotec epoxy sealant forms a strong bond with the substrate and
remains flexible after curing, therefore avoiding this common problem. This epoxy has also
demonstrated very good resistance to humidity under aggressive thermal cycling testing. The maximum
recommended operating temperature for the epoxy sealant is 80C.Ferrotec epoxy sealant can be
