keep the nozzle clean!!

Cleaning of Mix Chambers

Fusion AP AR2929 Mix Chamber uses three different drill sizes: nozzle, counter bore & impingement ports Probler P2 03 Mix Chamber uses two different drill sizes: nozzle insert & impingement ports 2013 PDA Annual Conference Flamingo Las Vegas Hotel and Casino April 15 – 17, 2013 *Using the Proper Size Drill is a Must!

Tools To Check Drill Sizes

You need to know your Drill Size. Learn to read a Micrometer or Use a Drill Gauge. 2013 PDA Annual Conference Flamingo Las Vegas Hotel and Casino April 15 – 17, 2013

Set-Up Of Proportioner Used in the PDA Class and Test Spray

Proportioner:

• Graco EXP-2 Electric Reactor, 50’ x 3/8” Diameter Heated Hose, Fluid Temperature

Sensor (FTS), 10’ x ¼” Heated Whip Hose, Complete Recirculation System. Transfer Pumps:

• Graco T1

(Both A – ISO & B – Poly) Spray Guns:

• Graco Fusion Air Purge
• Graco Fusion Mechanical Purge

Material:

• Pre-warmed with Power Blankets to 80˚F.

**All of this material was sprayed out of the same batch and sprayed on the same day, one after the other. 2013 PDA Annual Conference Flamingo Las Vegas Hotel and Casino April 15 – 17, 2013

Viscosity Profile

Viscosity Profile of Polyurea System

Manufacturer ETECO Inc. Material T6011

Temperature Component A ISO (cps) Component B Poly (cps) 75˚F 1340 cps 400 cps 85˚F 1000 cps 290 cps 95˚F 740 cps 200 cps 105˚F 580 cps 140 cps 115˚F 480 cps 90 cps 125˚F 360 cps 70 cps 135˚F 290 cps 60 cps 145˚F 240 cps 50 cps 150˚F 200 cps 50 cps 155˚F 180 cps 45 cps

Knowing the viscosity of A (ISO) & B (POLY) material before spraying will help you stay balanced (within 200-300psi) when spraying. First, select the temperature closest to where both materials are equal in viscosity then set the temperature set points on your Proportioner for the A (ISO) & B (Poly). Ask your material supplier for a viscosity profile.

Physical Property Testing Definitions

Tensile Strength The ability of a material to withstand a load under tension, i.e. when being pulled apart. It is expressed in pounds per square inch (psi). Elongation The amount a product will stretch under tension before it breaks. Expressed in percent of its original length, i.e. a tensile elongation of 10% means the product stretched 10% more than its original length before breaking. Modulus of Elasticity A value that is the ratio of the breaking strength to the deformation at break of a given

• material. It indicates the relative rigidity and strength of a material. The ratio of normal

stress to corresponding strain of a material. The ratio of normal stress to corresponding strain for tensile or compressive stresses below the proportional limit of the material; referred to as elastic modulus or Young's modulus. Die "C" Tear, pli The amount of force required till break of the "pre-notched" sample. Hardness The relative resistance of a material to scratching. Hardness, Shore A A measure of elastomer hardness. Hardness, Shore D A measure of elastomer hardness.

Thanks to ETECO for Supplying the Polyurea Material for the PDA Class and Doing the Testing for this Presentation. They are a New Member of PDA (March 2013.) 2013 PDA Annual Conference Flamingo Las Vegas Hotel and Casino April 15 – 17, 2013

Review of Findings

• When will the Physical Property be different?
• Different Spray Guns (Air Purge VS. Mechanical Purge)
• Different Mix Chambers (Round VS. Flat)
• Different if using Static Mixer Air Purged VS. Static Mixer Solvent Flushed
• Polyurea Manufactures should have their Polyurea Systems tested using

different Guns, Mix Chambers (round VS. flat) and then compare the Physical Properties. Now they will know the best process parameters for their systems. This information should be in the Technical Data Sheet.

• Last thing Polyurea Manufactures make Part A (ISO) and Part B (POLY).

You the applicator make Polyurea. Using the right Equipment, Gun and Process will allow you to make a Quality Polyurea Coating. 2013 PDA Annual Conference Flamingo Las Vegas Hotel and Casino April 15 – 17, 2013
