There are currently 8 names in this directory beginning with the letter G.
G
Galvanizing
A process whereby the pretreated steel is given a coat of zinc by immersion in the molten metal.
Gardner color scale
A system of color standards based on stable solutions of ferric chloride used in evaluation of resins, lacquers, oils and varnishes. The Gardner Scale can be correlated roughly with other color standards such as FAC, ASTM, NPA and Lovibond.
Gel
(1) A semi-solid system consisting of a network of solid aggregates in which liquid is held.
(2) The initial jelly-like solid phase that develops during the formation of a resin from a liquid.
Gel coat
The first coat of laminating resin laid up against a mold. The first layer of laminating material is then laid up on this resin after it has hardened or “gelled” slightly.
Gel point (time)
The stage at which a liquid begins to gel or exhibit pseudo-elastic properties. This stage may be observed from the inflection point on a viscosity-time plot.
Glass transition temp (Tg)
The temperature below the melting point of a polymer at which the temperature dependence of volume and other thermodynamic variables show a marked change of gradient. It is the temperature (T) at which the polymer passes from the glassy state (when T is below Tg) to rubbery state( when T is above Tg)
