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.

Dynamic wetting agents provide surface tension reduction and efficient wetting of pigment surfaces.
Even so, many composts with wetting agents simply hold too much water for the good of plants such as lavender.
With constant development of new silicones and novel wetting agents, the company is moving into group transfer polymerization, which is the next generation of wetting and dispersing agents.
The global Interface & Performance Business Line offers specific expertise in: release coatings for labels and hygiene applications; additives and processing aids for the manufacture of plastics and rubber, fluff pulp, tissue and textiles; wetting agents for safeguarding the efficacy of plant protection agents; as well as additives for building protection and metalworking fluids; and binders for adhesives and sealants.
The company also offers AEROSOL surfactants, which as wetting agents offer fast dynamic and deep efficient wetting to enable faster operating line speeds.
However, recent tests have shown that the surface tension of 2K waterborne epoxy coatings does not vary much through the duration of its pot-life; therefore, efficient, low-foam wetting agents, such as Surfynol[R] 420 surfactant, can maintain excellent surface appearance and wetting properties during this time.
