Surface Tension Effects in Waterborne Coatings -- 2014-02-12

Surface tension can be considered in various ways, but perhaps best as a result of the forces of attraction existing between the molecules of a liquid. It is measured by the force per unit length acting in the surface at right angles to an element of any line drawn in the surface (mN/m). Wetting is the effect of displacing one fluid from the substrate surface by another liquid. In general, the liquid must have the same or a lower surface tension than the substrate; otherwise, no wetting wil ...

Surface tension and surface energy -- 2014-02-12

The interfacial tension of a liquid to the air interface is termed surface tension. This is the energy which is required to bring a particle from inside a liquid to the air interface. The surface of the liquid is enlarged. Attractive forces act between the molecules of the liquid. Inside the liquid, these forces cancel each other as they act uniformly in all directions. At the interface, the resulting force is oriented towards the interior of the liquid; the liquid tries to reduce its surface ar ...

Substrate Wetting with Silicone Surfactants -- 2014-02-12

When a liquid coating is applied on a substrate, it is expected, that it will wet that substrate easily and evenly. Good wetting is necessary for an optically perfect surface, good adhesion to the substrate and full functionality of the coating (substrate protection). Most important for the substrate wetting are the surface tension values of the involved materials: the liquid coating and the solid substrate. In general, for good substrate wetting the surface tension of the coating material (p) ...

Silicones as Surface-Active Agents -- 2014-02-12

Silicones are highly surface active due to their low surface tension caused by the large number of methyl groups and due to the small intermolecular attractions between the siloxane hydrophobes.  The siloxane backbone of the molecule is highly flexible, which allows for maximum orientation of the attached groups at interfaces.Silicone polyethers are non-ionic and have both a hydrophilic part (low-molecular-weight polymer of ethylene oxide or propylene oxide or both) and a hydrophobic part ( ...

Silicone Surfactants for Coating -- 2014-02-12

As shown above, by adjusting the polarity it is possible to synthesize silicone additives which are compatible with aqueous coating systems. However, oftentimes it is observed, that the efficiency of such additives is not sufficient, especially when wetting of low energetic substrates (plastics) is concerned. The water content in these coating systems creates a relatively high surface tension(higher than in solvent-based coatings) which is reduced by the silicone additives, but oftentimes is sti ...
