Anodic Flame-sprayed aluminum and inorganic zinc are examples of a. Inhibitive coatings b. Barrier coatings c. Resistance coatings d. Sacrificial coatings ANSWERV V d. Sacrificial coatings The most basic function of any coating is its ability to to the surface on which it is placed. a. Adhere b. Bond c. Emulsify d. React ANSWERV V a. Adhere is the key to coating performance and long life. a. Strong cpoxy b. Strong adhesion c, Weak adhesion d. Perfect condition(s) ANSWER¥ ¥ b. Strong adhesion Adhesion can be chemical, , polar or a combination of all three. a. Mechanical b. Electrical c. Nuclear d. None of the above ANSWERV V a. Mechanical The most effective bond is the bond, which is formed by a reaction between the coating and the substrate. A coating must exhibit a variety of properties to fulfill its role in corrosion control. Desirable properties include: a. Flame resistance b. Chemical resistance c. Ease of application d. band ¢ above ANSWERV V¥ d. b and ¢ above Binders made from living or once living things are found in: a. Organic coatings b. Inorganic coatings c. A and b above d. None of the above ANSWERV V a. Organic coatings Broadly speaking, the major performance difference between organic and inorganic coatings is: a. Chemical resistance b. Heat resistance c. Electrical resistance d. None of the above ANSWERV ¥ b. Heat resistance Most industrial and marine coatings are Inorganic coatings. a. Truc b. False ANSWERV ¥ b. False Liquid-applied coating components are characterized by Pigment, Resin/binder, Solvent and a. Additive b. Vehicle c. Spray gun d, Acrosol ANSWERV V b. Vehicle A discrete particulate solid used to impart specific properties to the coating in the liquid and solid state is called: a. Additive b. Pigment c. Binder d. Solvent ANSWERV ¥ b. Pigment are most commonly liquid components of a coating typically added in small amounts to perform a specific function and each one give the individual product its unique characteristics. a. Pigment b. Resin c. Additives d. Solvents ANSWERV ¥ c. Additives The backbone of the coating which supplies most of the heavy-duty features and functions of the material is called the a. Binder b. Solution c. Solvent d. Resin ANSWERV ¥ a. Binder b. structural c. viscosity d. chemical ANSWERV ¥ d. chemical Once applied, nonconvertible coatings can be redissolved in the original solvent. a. True b. False ANSWERV V a. True Because they can be redissolved, nonconvertible coatings are sometimes referred to as material. a. thermoset b. thermoplastic ¢. organic d. non of the above ANSWERV ¥ b. thermoplastic Convertible coatings cure by one of several polymerization mechanisms, even when solvent evaporation is also involved. a. True b. False ANSWERV ¥V a. True ‘The resins used in convertible coatings undergo a chemical change as the cure progresses, so the resulting film is not readily redissolved in the solvent(s) used in application.
