solvents leave, particles coalesce.

keep components separate.
How do silicone high-temp coatings and baked phenolic coatings cure? - ANS-By baking.
How does a sacrificial coating provide corrosion control? - ANS-By using a more active metal as
the coating, it sacrificially corrodes instead of the underlying metal, protecting it from corrosion.
How does a Salt Meter work? - ANS-Measures the level of soluble salts much faster than Bresle
Patch Test.
How does colder temperature affect cure times? - ANS-Colder temperatures require longer cure
times.
How does density affect productivity? - ANS-Higher density leads to increased productivity.
How does general corrosion affect the surface? - ANS-Results in general thinning of affected
surface.
How does high air temperature affect mixing and thinning paint? - ANS-It reduces induction
time, pot life, and re-coat window.
How does high RH affect coating application? - ANS-Causes solvent entrapment and blistering.
How does higher air temperature affect coating windows? - ANS-Higher air temperature can
accelerate solvent evaporation and reduce coating windows.
How does low surface temperature affect curing? - ANS-It slows down curing and affects the
re-coat window.

How does non-convertible coating cure? - ANS-Through solvent evaporation with no chemical
change.
How does temperature affect solvents? - ANS-Affects evaporation time and curing rates, leading
to defects.
How does the Bresle Patch Test work? - ANS-Soluble salt on surface dissolves into water, fluid
is extracted and conductivity is measured.
How does wind affect solvent evaporation? - ANS-Wind can accelerate solvent evaporation.
