Wetting agents are surfactants and reduce the surface tension between the binder solution and the pigment particles. Wetting agents used in paint technology include calcium, zinc octoate, or naphthenate, fatty alcohol sulfonates, castor oil acid derivatives, and conversion products, poly(glycol ethers), and low-viscosity silicone oils. [Pg.49]

Gemini surfactants have been obtained from a trisiloxane amine, D-gluconic acid 5-lactone and oligoethylene glycol diglycidyl ethers [89] (Scheme 6). These surfactants reduced the surface tension of water to approximately 21 mN/m at a concentration of around 10 mol/L and showed two critical aggregation concentration values. [Pg.222]
