Learning Objectives

Learn about corrosion resistant coatings, coating selection for extending lifecycles thus reducing costs and infrared reflective pigments.

Obtain broad knowledge of performance coating systems

Learn about

coatings performance in terms of lifecycle of generic types of coating systems

Learn about

infrared reflective pigments and how they can reduce energy costs, stress on structures and increase the lifecycle of commercial coating systems.Slide5

Coatings lifecycle versus costParameters$84.00 per hour labor rate for northern California60 square feet per hour production rate per coat = $1.40 labor cost per square foot per coat.Establish commercial average cost per square foot of coating. Establish average lifecycle for each coating system. Slide16

Generic coatingsDefinitionsEpoxy: surface tolerant epoxy primerOrganic zinc: zinc powder in epoxy or urethane resin primerMinimum 19 lbs. of zinc per gallonInorganic zinc: zinc powder in silicate matrixMinimum 14 lbs. of zinc per gallon

Industrial urethane: acrylic aliphatic polyurethane with crosslink density of 600-800, industrial pigments, finish coat Automotive urethane: acrylic aliphatic polyurethane with crosslink density of 370-500, automotive pigments, finish coatFluorinated acrylic: fluoro-polymer acrylic finish coat for field application

Polysiloxane epoxy: oxidized silicone combined with an epoxy creating a weatherable epoxy finish coat Slide17

IR Reflective CoatingsStudy – UNLV EngineeringThermal Performance Analysis of Highly Reflective Coating on Residences in Hot and Arid Climates. By Samir F. Moujaes

P. E., PH.D. and Richard Brickman PH.D.Study confirms a decreased load on air conditioning equipment …“On a typical day in the summertime, a 41% reduction is shown to exist where the roof and walls are coated…”

“Roof plus wall combination reduces energy consumption by about 33.3%.”Slide28

Visible vs. IR Spectrum In the near infrared spectrum the color (heat) reflected is a white

In the visible spectrum the color (light) reflected is blackSlide29

IR Reflective PigmentsSynthetic mineral inorganic pigments Possess high infrared spectrum reflectivityReactions to create IR reflective pigment take up to 24 hours at 1800 to 2200 degrees FahrenheitExtremely stable against environmental degradation Slide30

Atlanta Heat Growth30Slide31

Advantages of IR Reflective PigmentsBuildings using IR reflective technology on exterior walls and roofs use less energy, are cooler and

more pleasant for the occupants.Products utilizing reflective technology are likely to have a longer service

life. Lower surface

temperatures will

lessen

chemical and

atmospheric degradation

and

also lessen expansion

and contraction

.

For

every 5% more

reflectivity,

a roof is

approximately 4 degrees Fahrenheit cooler
