What bis ban banode? b- bCorrect b bAnswer b- bThe banode bis bthe barea bof bthe bmetal bsurface
bthat bcorrodes. bThe bmetal boxidizes b(gains boxygen), bcausing bit bto blose bmass band bdissolve
binto bthe belectrolyte.
What bis boxidation? b- bCorrect b bAnswer b- bOxidation bis ba bchemical breaction bthat boccurs bat
bthe banode bwhere bthe bmetal bloses belectrons.

bto bslow bdown bthe breaction bat bthe banode, bor bcathode, bor bboth. bThey bcontain bspecial
bpigments bthat breact bwith bmoisture bor boxygen band bform ba bhard, bnon-reactive bsurface bfilm
bthat binterferes bwith bthe bcorrosion bprocess.

In bits bunmixed bform, bpigments bare bpowders.
What bare bbinders/resins? b- bCorrect b bAnswer b- bBinders/resins bare bliquids bthat badhere bto
bthe bsubstrate band bchemically bchange b(cure) bto bform ba bhard, bprotective bfilm.
What bare bsolvents? b- bCorrect b bAnswer b- bSolvents bare bthe bliquid bcomponents bof bthe
bcoating bthat bare bresponsible bfor bdissolving bthe bsolid bbinder/resin.
What bare badditives? b- bCorrect b bAnswer b- bAdditives bare bspecial bingredients bused bto
benhance bthe bperformance bor bcertain bproperties bor bcharacteristics bof bcoatings. b
They bare bcommonly bliquid bcomponents bthat bare badded bin bsmall bamounts.
