Definition

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

Purpose

The purpose of a wetting agent is to improve the spreading and penetration of liquids on solid surfaces, enhancing the effectiveness of coatings, cleaners, and other products that require thorough wetting.

Examples of Use

  • Agriculture: Wetting agents in pesticides to improve coverage on plant surfaces.
  • Cleaning Products: Enhancing the ability of detergents and cleaners to penetrate dirt and stains.
  • Paints and Coatings: Ensuring even application and adhesion of paints and coatings to surfaces.

Related Terms

  • Surfactant: A substance that reduces surface tension, often used interchangeably with wetting agent.
  • Surface Tension: The elastic tendency of liquids that makes them acquire the least surface area possible.
  • Capillarity: The ability of a liquid to flow in narrow spaces without the assistance of external forces.

Notes

Wetting agents are critical in various industries for improving the performance of products that require efficient wetting and spreading. They are formulated to work with specific liquids and applications.
