As a manufacturer, viscosity specifications need to be developed and defined by R&D for the products used in specific conditions – often customization of recipes is required. To ensure a stable viscosity performance in production tests need to be run daily. The new byko-visc RT provides you all the flexibility needed for any measurement task.

Guide to Viscosity Measurement

Viscosity is an important property of liquids to determine how they flow, spread, or level under certain conditions. It can be defined as a liquid’s internal resistance to flow. Being able to measure the viscosity will allow to predict the behavior in a process or an application. When applying a paint by roll application the paint viscosity will strongly influence the amount of paint applied per surface area, thereby determining both yield and hiding power. It is crucial for liquid products to undergo a viscosity measurement in incoming and outgoing QC.
