Wetting agents

The addition of wetting agents promotes reduction of surface tension of the preparation water, causing a better dispersion of the body. With the help of wetting agents, the plasticity of clay containing ramming and extruded bodies having the same amount of preparation water can be increased or, respectively, the amount of preparation water can be decreased while maintaining the same plasticity. Wetting agents make the forward motion of the extruded body more uniform over the entire cross-section. The use of wetting agents further makes it possible to incorporate compounds that are normally difficult to wet, such as for example carbon, more readily and the result is a more homogeneous composition of the batch.
