Liqui-Bond EA 1805是一種雙組份環(huán)氧基液體粘合膠。Liqui-Bond EA 1805具有導(dǎo)熱系數(shù)為1.8 W / mK
Liqui-Bond EA 1805將是一個(gè)雙組分的格式包裝，而不需要冷藏。
Liqui-Bond EA 1805這種混合材料能夠在室溫下固化，并且加熱能夠加速固化，粘結(jié)強(qiáng)度高。高粘結(jié)強(qiáng)度消除了緊固件的需要，并在惡劣的環(huán)境中保持結(jié)構(gòu)粘結(jié)。推薦使用填充熱源與散熱器之間的任何類似的金屬表面的表面的不規(guī)則性。Liqui-Bond EA 1805具有觸變性，并將分配過程中保持不變，和材料的流性對(duì)部件最小應(yīng)力，對(duì)敏感的組件產(chǎn)生很小的壓力。最小的膠層具有非常低的壓力很適合脆弱的部件裝配。
典型的應(yīng)用包括：
· 發(fā)光照明
· 電力供應(yīng)
· 分立元件的散熱器
· 汽車照明
