Abstract
An improved formula for coolants resists precipitation of the silicates due to interaction with flux residue contains of 2-[Methoxy (polyethyleneoxy)propyl] trimethoxysilane or reagents with similar structure and polarity. These silanes are used as additives to reduce or prevent precipitation in systems made from aluminum or aluminum alloys.
