Coating based on a synthetic resin dissolved in organic solvent. Dries by
solvent evaporation. The film remains susceptible to attack by the same or
Typical lacquers include those based on nitrocellulose, other cellulose derivatives,
vinyl resins, acrylic resins, etc.
Paint containing colloidal binder particles formed by emulsion polymerization.
A common term for water-based and water-reducible coatings.
Ability of flat pigments to align themselves more or less parallel with the
coated surface. This property produces a reflective appearance of the film.
Additive which is able to reduce the surface
tension under dynamic and static conditions, to obtain an optimal wetting
and leveling effect, and to improve the surface flow of the coating. Poor
surface flow can induce coating defects such as orange-peel, craters, brush
Softening and raising or wrinkling of a previous coat by the application of
an additional coat; often caused by coatings containing strong solvents.
Chemical decomposition and structural changes in polymers under the action
of UV light. Light degradation can cause coating defects such as internal
stress, loss of adhesion, cracking ... . Light degradation can be inhibited
by using UV / Light
See UV / Light stabilizer
Dispersion of surfactants and water-soluble polymers in water. Liophilic dispersions are
thermodynamically stable and reversible.
Dispersion where the dispersed phase has a low
affinity toward the medium liquid. Polymer latexes and pigment suspensions
are typical liophobic dispersions.
Additive used to aid in the reduction of friction between two parts.
Special pigment available to produce striking effects in the dark. Basically there are two
types: one is activated by ultra-violet radiation, producing very strong luminescence and,
consequently, very eye-catching effects; the other type, known as phosphorescent pigments,
does not require any separate source of radiation.
