Effect On Work Material
Certain laminating techniques use two steps of applying the epoxy to form resin impregnated fiber glass sheets. In the first step there is a resin solvent mixture which is partially cured so it will not redissolve in a second coating of the same mixture. The same resin mixture is subsequently given to the covered fiberglass with moderately cured resin in the second step. This second glaze which covers the first fills in the empty spaces between the fibers. The second coating is also only partially cured. This partial curing of the second layer furthers the curing of the first epoxy layer. This process also produces a thin sticky layer. The first coating acts like a sealed insulating sheet, preventing glass fiber contact with conductive planes. The second coating fills the planes and can form adhesive bonds to cores and conductive layers.

Famous quotes containing the words effect, work and/or material:
“Self-denial is not a virtue: it is only the effect of prudence on rascality.”
—George Bernard Shaw (1856–1950)
“They give us a pair of cloth shorts twice a year for all our clothing. When we work in the sugar mills and catch our finger in the millstone, they cut off our hand; when we try to run away, they cut off our leg: both things have happened to me. It is at this price that you eat sugar in Europe.”
—Voltaire [François Marie Arouet] (1694–1778)
“This country is at present engaged in furnishing material for future authors; not in encouraging its living ones.”
