When selecting the correct system for your application, the material’s properties, including viscosity and deposit size, are important considerations. Viscosity is the measurement of a fluid’s internal resistance to flow. This is usually designated in units of centipoise or poise, but can be expressed in other measurements as well. Refer to the chart below. 100 Centipoise = 1 Poise 1 Centipoise = 1 mPa•s (Millipascal Second) 1 Poise = 0.1 Pa•s (Pascal Second) Centipoise = Centistoke x Density APPROXIMATE VISCOSITIES OF COMMON MATERIALS (at room temperature — 21 °C [70 °F]) Material Viscosity in Centipoise Water 1–5 Kerosene 10 Anti-freeze or Ethylene Glycol 15 Motor Oil SAE10 50–100 Motor Oil SAE30 or Maple Syrup 150–200 Motor Oil SAE40 or Castor Oil 250–500 Motor Oil SAE60 or Glycerin 1,000–2,000 Corn Syrup or Honey 2,000–3,000 Molasses 5,000–10,000 Chocolate Syrup 10,000–25,000 Ketchup or Mustard 50,000–70,000 Tomato Paste or Peanut Butter 150,000–250,000 Shortening or Lard 1,000,000–2,000,000 Caulking Compound 5,000,000–10,000,000 Window Putty 100,000,000 Typical Assembly Materials Dispensed with EFD Systems • Activators • Anaerobics • Coatings • Cyanoacrylates • Electrolytes • Epoxies “We ordered supplies yesterday and 17 hours later, they arrived! 2 years and never a problem of any kind.
