In the Spektrochem laboratory, we use the Stormer digital viscometer (ASTM D562 method B). One of the basic rheological evaluations is the measurement of low-shear viscosity consistency according to ASTM D562. spatter resistance (roller application) – ASTM D4707.viscosity measurement with viscometer with defined shear rate – ISO 3219.viscosity under changing speed, shear thinning and thixotropy – ASTM D2196 method B.apparent viscosity (Brookfield) – ASTM D2196 method A, ISO 2555.low-shear viscosity (consistency) – ASTM D562.
ASTM D4400 – Resistance to sagging testĪ typical range of laboratory tests to determine the application properties of paints includes: Application with a spreading rate, leveling, consistency, brush marks, … these are only some of the parameters that we test in our laboratory when selecting raw materials and formulating a recipe for latex paints. Proper application of the paint on the wall or ceiling guarantees not only its aesthetic appearance, but also ensuring the formation of a coating with appropriate properties.
