W HAT IS A D RY -F ALL C OATING ? A coat ating, when spray ap ay applied, i , is powder d dry ry in in a as s lit little as s 8-10 f 0 feet from om the the poi point of of appl pplication. Also known as: Dry-Fog Coatings Spray-Safe Coatings
W HY U SE D RY -F ALL C OATINGS ? Eliminate Overspray Worries in Congested Areas Can be approved to use in no-spray zones Avoids costly encapsulation Alternative to Brushing & Rolling OVERSPRAY
O VERSPRAY C LAIMS C AN B E C OSTLY Overspray can damage nearby cars, equipment and can also be a hazard to the environment.
I S O VERSPRAY A CONCERN ? YES
W HY U SE D RY -F ALL C OATINGS ? Decrease Labor Costs (at least 4X faster than brushing and rolling) Extend Maintenance Budgets Complete Coating Repairs more Quickly- Less Down-Time
T HE HE E VOL OLUTION OF OF D RY -F AL ALL C OATIN INGS Originally formulated for interior applications, Dry-Fall or Spray-Safe technology was developed to offer a fast-dry/ less-mess solution for residential and commercial uses. These formulas were traditionally offered in a flat finish only. Over the years, formulas were adapted to move interior solutions to exterior solutions in both water-borne and solvent-borne options.
W ATER ER - BOR NE VS . . S OLVENT - BOR NE ORNE ORNE • Water Soluble (solutions) Water-borne • Water Dispersible Coatings (Dispersions) • Emulsions (Latex) • Standard Solvent-borne • Low VOC/ VOC Exempt Coatings • High Solids
W ATER -B ORNE C OATINGS : PROS & C ONS Pros Pro Cons ns Usually lower solids/ Can reduce VOC and hard to control film HAP emmissions* thickness/ runs & sags Good storage life Flow properties and Easy to clean up dry times change with humidity Low odor Can promote flash Dried paint may be rusting when used as a disposed of in a a primer landfill as non Longer dry times hazardous waste Reduced temperature * Not all waterborne coatings • resistance have lower VOC or HAPs ratings
S OLVENT -B ORNE C OATINGS : P ROS & C ONS Pros Pro Cons ns Available in low VOC Can be more difficult and HAP ratings* to repair Reduces number of 2-K products may spray applications to have shorter pot life achieve target DFT Harder to clean up Improves abrasion Can have higher VOC and mar resistance content More surface tolerant Decreased flexibility Better adhesion/weatherabi in application equip. lity

Typical Applications Cranes/Tall Storage Piping and Sructures Tanks Pipe Racks and more
Typical Applications (Continued) High Near Complex Temperature Waterways Structures and more
