Terms and definitions of painting
Some of the main definitions applicable to a painting process are defined below: Corrosion Ability of an environment to cause corrosion in a given system Curing Hardening of the liquid paint by heat or by chemical reaction Curing Agent Is the component which produces the…
VISCOMETER
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. For example, paint needs to…
Airless Sprayer Tip Sizing Guide
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 can save you time and…
Holiday Testing
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 to find coating film discontinuities…
