5. What are Volatile Organic Compounds (VOCs)? - ANSWER ✔ Chemicals
that easily evaporate at room temperature.
6. What are solvents? - ANSWER ✔ Substances that dissolve other substances
to form a solution.
7. Why can solvents in coatings be harmful? - ANSWER ✔ Because they can
release VOCs into the air.
8. What are some examples of solvents used in coatings? - ANSWER ✔
Acetone, toluene, xylene, and ethyl acetate.
9. What are three commonly used galvanic anodes for carbon steel? -
ANSWER ✔ Zinc, Aluminum, and Magnesium
10.What is the effect of temperature on corrosion rate? - ANSWER ✔ Decrease
in temperature decreases corrosion rate.
11.What is an electrolyte? - ANSWER ✔ A medium that carries ionic current.
,12.What is sacrificial coating? - ANSWER ✔ A type of coating that becomes
the anode of an electrochemical cell.
13.What is stripe coating? - ANSWER ✔ The application (by brush or spray) of
an extra coat of paint to edges, welds, fasteners, corners, and other irregular
areas, before or after a full coat is applied.
14.What is SSPC-PA Guide 11? - ANSWER ✔ A guide for protecting edges,
crevices, and irregular steel surfaces by stripe coating.
15.What does SSPC-PA Guide 11 focus on? - ANSWER ✔ Protecting edges,
crevices, and irregular steel surfaces by stripe coating.
16.What are roller applications used for? - ANSWER ✔ Large, flat areas that
don't require a smooth finish.
17.What are some concerns with rollers? - ANSWER ✔ Loose nap fibers, wet
edges, incorrect nap thickness, uneven finish, orange peel, insufficient DFT,
inability to penetrate pores, cracks or surface irregularities.
18.What is spray application? - ANSWER ✔ Backbone of industrial coating
industry with wide-ranging application.
19.What are the advantages of conventional sprayers? - ANSWER ✔ Finer
atomization, uniform/high quality finish, greater control on flow rate,
suitable for wide variety of coating material.
, 20.What are the disadvantages of conventional sprayers? - ANSWER ✔
Require thinners, lower production rate compared to airless spray, low
transfer efficiency, increase in material cost, incompatible short pot lives.
21.What should inspectors be concerned with regarding conventional spray
systems? - ANSWER ✔ Insufficient pressure, contaminated air, overspray,
incorrect equipment setup, over thinning.
22.What is High-Volume Low-Pressure (HVLP) spray system? - ANSWER ✔
A system that uses high volume of air at low pressures to propel coating
onto the substrate.
23.SSPC-SP 1 - ANSWER ✔ Solvent Cleaning
-Defines that the end condition of a solvent-cleaned, metal surface, "shall be
free of visible oil, grease, dust, dirt, drawing and cutting compounds, and
other visible soluble contaminants, when viewed without magnification
-Invoked by nearly all SSPC and NACE surface cleanliness standards,
including power tool cleaning and abrasive blast cleaning
24.ISO 8504-3 - ANSWER ✔ Solvent Cleaning
-removing visible oil, grease, soil and machining lubricants
-removing non-visible soluble contaminants from steel surface
-used before hand or power tool cleaning
25.SSPC-SP 2 - ANSWER ✔ Hand Tool Cleaning
-Manually chipping, scrapping, brushing, and sanding the surface to remove
foreign material
-can typically remove ALL loose mill scale, coatings, rust, and other loose
detrimental materials
-This method along CANNOT be used for most high-performance coating
systems or systems that require a truly clean substrate
