wetting agent

[′wed·iŋ ‚ā·jənt]
(chemical engineering)
A substance that increases the rate at which a liquid spreads across a surface when it is added to the liquid in small amounts.
(graphic arts)
A substance that renders a surface nonrepellent to a wetting liquid.

wetting agent

A substance capable of lowering the surface tension of liquids, facilitating the wetting of solid surfaces, and permitting the penetration of liquids into the capillaries.
