EXAM QUESTIONS
QUESTION 1
Colors
CORRECT ANSWER
Primary colors- red, yellow, blue
secondary- orange, green, violet (mix equal amounts of 2 primary)
intermediate (tertiary)- mix primary and secondary next to each other on wheel
complementary- two colors on opposite ends of wheel
Split complementary- three colors, any color + two colors next to complementary
RATIONALE: This explanation accurately categorizes colors based on their relationship and properties, specifically using
the color wheel as a visual representation to demonstrate how colors interact and mix. By defining primary, secondary,
intermediate, complementary, and split complementary colors in relation to the color wheel, the explanation provides a
logical and systematic approach to understanding the characteristics of different colors.
QUESTION 2
Paint chemistry
Trusted by thousands of students and professionals worldwide Page 1 of 20
, CORRECT ANSWER
paint- mix of pigment in suitable liquid: purpose protection, decoration, information
Ingredients
1. Vehicle-form liquid portion, adhere paint to surface, bind pigment
*binder(resin) + solvent
*carries ingredients to surface that will remain there
* ex. linseed oil, varnish, epoxy esters ( assist in formation of coating film & increase resistance to film
damage, improve drying time/gloss/adhesion/chemical reaction)
2. Pigments- give paint color opacity, gloss control, durability, ease of sanding, flame retardance, fill
space in subtrate
*primers & flat paints/ white paint (high%), gloss paints/ black paint (low%)
*insolube
*ex. zinc chromate, red lead, chrome yellow, titanium dioxide (main pig. for white)
3. Solvents- low viscosity (thickness) control consistency of paint, regulate application
*ex, turpentine, mineral spirits, lacquer thinner, water
4. Additives- modify properties of vehicle/pigment
*I. dryer: absorb moisture & accelerate drying (cobalt, lead, manganese, metals) more than 10% drier
makes paint film less durable
*II. plasticizers: increase flexibility and adhesion
*III. wetting agents: disperse pigments
*IV. other: defoamers, anti settling agents, preservative, fungicides, ultraviolet screens, acid neutralizers,
anti skinning agents, leveling agents
RATIONALE: The provided answer is correct because it lists the essential components of paint and their functions,
accurately categorizing them into vehicles, pigments, solvents, and additives, which are the fundamental building blocks
of paint chemistry. By breaking down paint into these core elements and describing their roles, the answer
demonstrates a comprehensive understanding of the complex interactions and relationships between paint ingredients
that determine its properties and performance.
QUESTION 3
Resins
CORRECT ANSWER
Natural resins- from sap of pine trees/other plants, found in near ground where trees had grown
1. rosin: pine trees (3 types)
*gum rosin- tapping live trees
*wood- distilled from tree stumps
*tall oil rosin- byproduct of conversion of pine to paper pulp
2. shellac: made of lac (female lac insects from India and Tibet) dissolved in alcohol, not soluble in
turpentine/oil based thinners. For sealing bleeding stains, dyes/pitch (sealing knots in wood)
Synthetic resins- byproduct of natural resins
1.alkyds- alcohol combined w/ organic acid.
*largely replaces linseed oil as vehicle when combined when vegetable oil
*best & most durable gloss, good color retention, high-quality whites
*poor resistance to solvents & chemical attacks
*dry faster than oil-based paints
2.epoxy- similar to alkyds, mixed together prior to use
*high resistance to oils, solvents, corrosion, alkalis
*used w/ two primers & two top coats
3.others- chlorinated rubbers, vinyl, silicone, urethane, acrylic, polyester resins
Trusted by thousands of students and professionals worldwide Page 2 of 20
, RATIONALE: This categorization of resins is correct because it distinguishes between natural resins derived from plant
sources, and synthetic resins produced as byproducts or through chemical reactions. The categorization effectively
groups like substances together, such as the three types of rosin and the range of synthetic resins including alkyds,
epoxy, and others, highlighting their shared characteristics and uses.
QUESTION 4
Protective coatings
CORRECT ANSWER
Latex paints/Emulsion paints
*thin, clean up w/ water
*dry quick, w/in an hour
*spread easily
*little odor
*less likely to show lap marks
*always used on ceilings, less acoustical interference
*applied on damp surfaces, less likely to blister
*vinyl, acrylic, PVA
Alkyd paints
*thin, clean up w/ paint thinner or similar
*synthetic resin binders mixed w/ oil vehicles
*dry quicker than standard oil-based paints
*good color retention
*more hiding power than latex
*best & most durable gloss
*poor resistance to solvent attack
Oil-based paints
*thin, clean up w/ paint thinner or similar
*high resistance to wear from rubbing
*apply when surface temp at max. to avoid surface blistering
Polyurethanes/Urethane/Synthetics/Plastic coatings
*thin, clean up w/ paint thinner or similar
*cure at low temp
*clear/tinted varieties
*high resistance to chipping
Varnishes
*thin, clean up w/ paint thinner or similar
*high resistance to wear from rubbing
*spar varnish- best weather resistance of all clear finishes
*Resin+Oil= Varnish
*Varnish + pigment/paint= Enamel
RATIONALE: This answer is correct because it accurately categorizes various types of coatings based on their
characteristics, such as drying time, clean-up requirements, and durability, allowing for a comprehensive understanding
of their properties and applications. By organizing these coatings into distinct categories, the answer effectively
illustrates the concept of protective coatings in a clear and structured manner.
