A fluid’s resistance to flow is its viscosity—the ratio of force required to overcome internal friction between layers of fluid (shearing stress) to the change in speed between layers of fluid (velocity gradient). Many quality control measures are based on viscosity.…
Picking the correct tip and size is essential for a quality finish and ease of use. This may seem a bit confusing or complicated at first but once you understand it, picking the right tip is not rocket science and…
Holiday testing is a non-destructive test method applied on protective coatings to detect unacceptable discontinuities such as pinholes and voids. The test involves checking an electric circuit to see if current flows to complete the circuit. This testing is used…
