ABSTRACT:
A corrosion inhibitor slurry is disclosed which is suitable for addition to a selected liquid coolant capable of dispersing at least one glycol having from 3 to 5 carbon atoms per molecule. The slurry consists of a mixture of (a) a treatment composition comprising corrosion inhibitor, capable of dispersing in said selected liquid coolant and consisting of solid and, optionally non-solid components; and (b) a liquid vehicle selected from glycols which have 3 to 5 carbon atoms per molecule and disperse in said selected liquid coolant. The treatment composition solids in the slurry are fine particles; the amount of vehicle in the slurry is chosen such that the particles are thoroughly wetted and the slurry both sets and is pumpable; and the amounts of non-solid components of the treatment composition are limited to a total quantity that does not substantially impair the pumping and setting characteristics provided by the particles and liquid vehicle. Cooling system filters charged with said slurries are also disclosed.
