存儲方法: 低溫、通風、干燥室內(nèi)避光密封保存。
主要用途
1 RTV樹脂和混合的硅烷交聯(lián)密封劑:本品是含有雙官能團的硅烷偶聯(lián)劑,加入單雙組分的硅烷交聯(lián)密封劑提高了多種基材的粘接力,包括玻璃、鋼、鋁和混凝土。當用做硅烷基化聚氨酯聚合體時,運用SPURSM技術,該硅烷能顯著提高對一系列塑膠的粘接力;
2 多硫化物密封劑:加入單雙組分多硫密封劑時,本品為多種基材提供了較好的粘接力,包括玻璃、鋁和鋼材。本品的一般用量為密封劑的0.5-1.0%重量份。該產(chǎn)品分散性很好且可得到內(nèi)聚脫裂而不是界面脫裂。另外,使用本品可免掉能促進涂層跟涂層表面粘接力的底漆;
3 保溫材料:在玻璃棉和礦物棉生產(chǎn)中,將其加入到酚醛粘結(jié)劑中,可提高防潮性及增加壓縮回彈性,并提高制品強度;
4 鑄造行業(yè):本產(chǎn)品適合于酚醛樹脂的覆膜砂工藝,可減少樹脂在硅砂中的用量,并可降低樹脂在高溫下的發(fā)氣量,極大的提高了砂芯的強度,從而使鑄件制品更具表面平整與光滑性,降低鑄造成本;
5 磨具磨料:在磨具行業(yè)中可提高金剛砂與樹脂的相容性能, 顯著提高制品的強度及韌性。適用的樹脂:酚醛、PA、 PU、 PC、三聚氰胺、丙烯酸、丁腈橡膠、 氯丁橡膠、RTV樹脂等
