电气绝缘

遮蔽反光

与所有电气设备一样,LED需要介电材料来使引线、电线和其他元件与串扰隔离。然而,随着LED设计和应用在数量和多样性方面不断扩展,内部的敏感电子元件也需要与其他环境因素隔离。制造期间和制造之后的热循环会对LED组件造成破坏性压力,而要求严苛的户外和汽车应用则会使LED暴露在更高的热量和冲击下。  

陶氏的有机硅涂料和灌封材料可帮助保护LED组件免受各种环境因素的影响。除介电绝缘外,陶氏的低模量密封剂可提供出色的机械冲击和振动保护。

如何选择有机硅? 

DOWSIL™ 3140 RTV涂料是一种流动性好的半透明粘合剂或涂料,高延伸率可提高振动/机械冲击阻尼性能,并具有低应力、良好的阻燃性,经过 UL、IPC 和军用规格测试,含有紫外线指示剂。  

SYLGARD™ 527 A&B 有机硅介电凝胶是一种双组分 1:1 混合比介电凝胶,用于密封和保护各种电子设备,特别是具有精密元件的设备  

DOWSIL™ 1-4105敷形涂料是一种单组分、透明、快速热固化、柔软、消除应力的产品,符合UL要求,含有紫外线指示剂。适合刚性和柔性电路板的防护涂层。
