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

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. 2013 PDA Annual Conference Flamingo Las Vegas Hotel and Casino April 15 – 17, 2013

  32. Physical Property Testing Definitions The ability of a material to withstand a load under tension, i.e. when being pulled apart. Tensile Strength It is expressed in pounds per square inch (psi). The amount a product will stretch under tension before it breaks. Expressed in percent of Elongation its original length, i.e. a tensile elongation of 10% means the product stretched 10% more than its original length before breaking. 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 Modulus of Elasticity 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. **Everyone should have this Glossary from PDA, it’s Very Helpful. 2013 PDA Annual Conference Flamingo Las Vegas Hotel and Casino April 15 – 17, 2013
