NACE CIP Level I Chapter 8: Coating Types
and Curing Mechanisms Exam Questions
And Answers
Curing Mechanisms - - -
correct answer ✅There are two broad classifications of curing
mechanisms:
* Nonconvertible
* Convertible
Nonconvertible Coatings - - -
correct answer ✅* Cure by evaporation of the solvent with no
chemical change to the resin
* Can be redissolved in the original solvent
* Because they can be redissolved, these types of coatings are
sometimes referred to as thermoplastic materials
* Been limited by VOC regulations in many part of the world
Evaporation Cure - - -
correct answer ✅* Cure solely by solvent evaporation
* No chemical change occurs upon evaporation
* Can be re-dissolved in the solvent
* Examples include vinyl and chlorinated rubber
* Typically thermoplastic materials

and Curing Mechanisms Exam Questions
And Answers
Coalescence - - -
correct answer ✅* Specialized case of evaporation
* Resins are dispersed in water
* The water evaporates, the resin particles fuse (coalesce)
* Typically known as latexes or acrylic latexes
Convertible Coatings - - -
correct answer ✅* Cure by one of several polymerization
mechanisms
* Resins undergo a chemical change
* Not readily re-dissolved in the solvent
* Known as thermosetting materials
* Some examples of curing types are: Oxidation, Co-reaction,
Hydrolysis, Fusion
Oxidation - - -
correct answer ✅* Cure by reaction with atmospheric oxygen
* Unsuitable for immersion service
