    金属减活剂T561是一种噻二唑多硫化物，它能捕捉油品中的活性硫，抑制金属的腐蚀。由于它含有多硫键，可与金属表面形成硫化膜，从而有效地抑制了金属离子对油品的催化作用，因而在改善油品的使用性能方面，T561是一种很有效的润滑油添加剂。在碱性高锌的抗磨液压油配方中，加入0.03-0.05%的T561金属减活剂，油品即可通过丹尼森HF-2水解安定性试验。在内燃机油配方中，加入0.4-0.5%的T561金属减活剂，油品的TFOUT诱导期可提高60min以上。此外，T561金属减活剂还可应用于工业齿轮油及优质汽油机油中。
    包装：25KG/桶  或200KG/桶
    该产品因价值较高，超过1吨需提前订购，需3-5个工作日生产周期。
