Viscosity describes how easily a liquid flows. A high-viscosity coating is thick and slow moving; a low-viscosity one is thin and runny. For paints and coatings this single property influences almost every stage of use, from how a product is pumped and dosed in production, to how it atomizes at a spray gun, to how…

Viscosity is a fluid's resistance to flow. In paints and coatings it governs how a product brushes, sprays, rolls, levels, and resists sagging, and it is one of the most routinely checked quality parameters on the line and in the lab. A coating that is too thick drags and clogs; one that is too thin…

Key terms Term  Definition  Viscosity  A fluid's resistance to flow.  Dynamic viscosity  Resistance to flow under an applied shear, measured in pascal seconds (Pa.s), poise (P), or centipoise (cP).  Kinematic viscosity  Dynamic viscosity divided by density, measured in centistokes (cSt); what a flow cup effectively reports.  Shear rate  The rate at which a fluid is…

To ensure that paints and coatings are easy to apply and durable in their nature, oils and additives are required. To know that the addition of these components doesn’t adversely affect the composition of your final paint or coating, you need thorough and efficient viscosity testing. Oils and lubricant additives in paint The addition of…

A viscometer is a device for measuring the viscosity of a sample. It is…

There’s been quite a move towards water based paints in recent years, thanks to a variety of environmental and safety concerns, but is it something you should be worrying about right now? We’ve put together some handy information to help you decide. The move towards water-based paints While solvent-based paints have many advantages, including longevity,…

Viscosity testing is absolutely essential if you want to be confident that your paints, inks, varnishes and coatings stay in one place! Over time, deformation or flow can have a disastrous effect on the appearance of products or packaging. Measuring viscosity during the test and measurement process allows you to choose the right materials for…
