Binders form a stable film that retains its properties.
,What is a barrier coating? - CORRECT ANSWER -
A coating that interrupts the electrolyte of an electrochemical cell.
What are two environments most susceptible to corrosion? - CORRECT ANSWER -
Marine Environment, Chemical with High Humidity Environment
What is the direction of electron flow in an oxidation reaction? - CORRECT ANSWER -
From the anode to the cathode through the metallic path.
What is the role of binders? - CORRECT ANSWER -
Binders bonds pigments together and adhere to surface.
What are solvents? - CORRECT ANSWER -Solvents are liquids that dissolve the solid resins.
What is the purpose of pigments? - CORRECT ANSWER -
Pigments hide the substrates, provide decorative color, and enhance desired properties.
What are additives? - CORRECT ANSWER -
Additives are special purpose ingredients used to enhance the performance.
What are vehicles? - CORRECT ANSWER -Vehicles are the liquid portions of the coating.
What is corrosion? - CORRECT ANSWER -
Deterioration of metal or alloy due to electrochemical reaction.
What is passivation? - CORRECT ANSWER -
Layer of oxides on metal surface for corrosion protection.
