Layer which prevents the passage of water into a material or structure.
Inpigmented binder-solvent solution that is converted to a transparent or
translucent solid film after application as a thin layer. Varnish is pplied
to protect or decorate a surface.
Liquid portion of a paint in which the pigment is dispersed. Comprised of
binder and thinner.
Resin resulting of the copolymerization of vinyl acetate and vinyl chloride.
Flow behavior of a liquid (or solid) having both viscous and elastic properties. A
viscoelastic liquid will deform and flow under the influence of an applied shear stress,
but when the stress is removed, the liquid will slowly recover from some of the deformation.
Viscoelastic flow is characteristic
of some gel-like substances and low Tg polymers (plasto-elastomers).
Measurement of a fluid's resistance to flow. The common metric unit of absolute
viscosity is the poise, which is defined as the force in dynes required to move
a surface one square centimeter in area past a parallel surface at a speed of
one centimeter per second, with the surfaces separated by a fluid film one centimeter thick.
Since viscosity varies in inversely with temperature, its value is meaningless
until the temperature at which it is determined is reported.
Additive modifying rheological behavior of a polymeric composition.
Syn. Rheology modifier, Thickener
Graphic representation of the shear viscosity function versus the shear rate
or the shear stress.
Syn. Viscosity curve
Volatile Organic Compound or liquid that is non-exempt.
Coating defect: holes in a coating application.
Amount of solvent or liquid components in a coating.
Irreversible process during which an elastomer, through a change in its chemical structure
(for example crosslinking), becomes less plastic and more resistant to swelling by
organic liquids. Its elastic properties are conferred, improved, or extended over a
greater range of temperature.
Compounding material that produces vulcanization.
