摘要:
Hydraulic fluid compositions having improved non-corrosive properties to metals are formed from (A) a hydraulic fluid containing a borate ester and (B) an oxyalkylated alicyclic amine.
摘要:
Hydraulic fluid compositions having a high boiling point and a boron content of 0.2 to 1.6% by weight are formed from (a) a reaction product of (i) a polyalkylene glycol monoalkyl ether, (ii) a polyalkylene glycol or (iii) a polyoxyalkylene mono- or poly- ol having a molecular weight of 1000 to 5000, with (iv) a boron compound; (b) a polyalkylene glycol monoalkyl ether; (c) a polyalkylene glycol and (d) a polyoxyalkylene mono- or poly- ol having a molecular weight of 1000 to 5000.
摘要:
Hydraulic fluid compositions having improved properties to rubbers are formed from (A) a nitrogen-atom-containing borate ester derived from an oxyalkylated heterocyclic or alicyclic amine and (B) another borate ester and/or polyoxyalkylene compound.
