Aftercompleting this module, you should be able to: 1.Define the following terms and concepts •Briefly describe the differences among the following types of paint: Automotive Paint, Structural (architectural) Paint, Bicycle Paint, Maintenance Paint, Marine Paint, Aircraft Paint •What is a polymer? •What is a paint? •What is the difference between a paint and a coating? •What are the two primary purposes of paint? •What makes a paint unique? •What is a paint vehicle? •What is a paint binder? •What is a pigment? •What is an extender pigment? List 5 of the more common extenders. •What is the major resin used in a paint formulation? •What is a paint additive? List at least 3. •What is a paint drier? List at least 5. •What is the difference between a thermosetting resin and a thermoplastic resin? •What is the most widely used white paint pigment? Name the two forms of this white pigment. How can these two forms of white paint pigment be distinguished from each other? •What metal pigment is used in metallic motor vehicle paint? •What is a primer? •What is a primer surfacer used for in automotive paints? •What is a substrate? •Name three types of latex polymers. •What is meant by the term “Let Down” in the paint industry?•What is meant by the term “Let Down” in the paint industry? •Is a wetting agent a vehicle or a binder? •Name several other synthetic binders (other than alkyds) that are used in paints. •Which white pigment is used as a mildew inhibitor? •What is the primary function inpaint?2.Determine the physical properties of paints and/or polymers to include: color, texture, thickness, layer sequence, metallic/nonmetallic/pearlescent, other surface characteristics. 3.Describe several methods to determine the layer structure of a paint chip when viewing the chip microscopically.
