GPC 251導電環(huán)氧膠粘劑

說明：GPC 251是一種由兩部分組成的室溫固化銀填充環(huán)氧膠粘劑。這個系統(tǒng)是

設計用于在電氣部件和裝置上制作電氣和機械附件。不像典型的

室溫固化系統(tǒng)，本產品具有優(yōu)異的導電性，對

操作和環(huán)境條件。免費的B組件允許定制終屬性，使用

B2612為了更高的靈活性和更低的應力，使用標準的B部件以獲得高強度的要求。

 GPC 251
ELECTRICALLY CONDUCTIVE EPOXY ADHESIVE
DESCRIPTION: GPC 251 is a two-part, room temperature curing, silver filled epoxy adhesive. This system is
designed for making electrical and mechanical attachments on electrical components and devices. Unlike typical
room temperature curing systems, this product always results in excellent conductivity and is less sensitive to
handling and ambient conditions. Complimentary B components allow for customization of end properties, use
B2612 for more flexibility and lower stress, use the standard B component for high strength requirements.
