2. Oil paint - Wikipedia

   en.wikipedia.org/wiki/Oil_paint

   Oil paint is a type of slow-drying paint that consists of particles of pigment suspended in a drying oil, commonly linseed oil. The viscosity of the paint may be modified by the addition of a solvent such as turpentine or white spirit , and varnish may be added to increase the glossiness of the dried oil paint film.

3. Tung oil - Wikipedia

   en.wikipedia.org/wiki/Tung_oil

   Tung oil or China wood oil is a drying oil obtained by pressing the seed from the nut of the tung tree ( Vernicia fordii ). Tung oil hardens upon exposure to air (through polymerization ), and the resulting coating is transparent and has a deep, almost wet look. Used mostly for finishing and protecting wood, after numerous coats, the finish can ...

4. Surfactants in paint - Wikipedia

   en.wikipedia.org/wiki/Surfactants_in_paint

   Common paint additives are catalysts, thickeners, stabilizers, emulsifiers, texturizers, biocides to fight bacterial growth, etc. The word surfactant is short for surface active agent. [1] Surfactants are compounds that lower the surface tension of a liquid, the interfacial tension between two liquids, or the interfacial tension between a ...

5. Viscosity - Wikipedia

   en.wikipedia.org/wiki/Viscosity

   Extensional viscosity can be measured with various rheometers that apply extensional stress. Volume viscosity can be measured with an acoustic rheometer. Apparent viscosity is a calculation derived from tests performed on drilling fluid used in oil or gas well development. These calculations and tests help engineers develop and maintain the ...

6. Viscosity models for mixtures - Wikipedia

   en.wikipedia.org/wiki/Viscosity_models_for_mixtures

   Viscosity models for mixtures. The shear viscosity (or viscosity, in short) of a fluid is a material property that describes the friction between internal neighboring fluid surfaces (or sheets) flowing with different fluid velocities. This friction is the effect of (linear) momentum exchange caused by molecules with sufficient energy to move ...

7. Wood stain - Wikipedia

   en.wikipedia.org/wiki/Wood_stain

   Wood stain is a type of paint used to colour wood comprising colourants dissolved and/or suspended in a vehicle or solvent. Pigments and/or dyes are largely used as colourants in most stains. The initial application of any paint or varnish is absorbed into the substrate similarly to stains, but the binder from a stain resides mainly below the ...
