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 on, effect, work and/or material:
“As for charity, it is a matter in which the immediate effect on the persons directly concerned, and the ultimate consequence to the general good, are apt to be at complete war with one another.”
—John Stuart Mill (18061873)
“This is the great truth life has to teach us ... that gratification of our individual desires and expression of our personal preferences without consideration for their effect upon others brings in the end nothing but ruin and devastation.”
—Hortense Odlum (1892?)
“During the first World War women in the United States had a chance to try their capacities in wider fields of executive leadership in industry. Must we always wait for war to give us opportunity? And must the pendulum always swing back in the busy world of work and workers during times of peace?”

“To-day ... when material prosperity and well earned ease and luxury are assured facts from a national standpoint, womans work and womans influence are needed as never before; needed to bring a heart power into this money getting, dollar-worshipping civilization; needed to bring a moral force into the utilitarian motives and interests of the time; needed to stand for God and Home and Native Land versus gain and greed and grasping selfishness.”
—Anna Julia Cooper (18591964)
