The hiding and spreading powers of pigmented coatings are of fundamental importance and there are many methods by which the opacity of a coating may be examined. These methods do not relate necessarily to painting practice as the change of appearance wanted, the contour and surface characteristics of the substrate together with the rheological properties of the paint will influence the performance of such coatings

Colors appear differently under different lighting sources. To avoid/reduce the assessment error when performing color contrast, we can make use of a Color Light Box to simulate different light sources to obtain an objective assessment of color…
This new Cone and Plate Viscometer is specially designed for this purpose. A highly accurate wear resistant cone rotating at high speed on a temperature controlled plate simulates the expected “real world” application shear.
The test method specifies suitable cutting tools with either single or multiple cutting edges. The cross hatch cutter in the form presented in the photograph, with either 1, 1.5, 2 or 3mm spaces between the cutting edges, has advantages over the single cutting blade for both safety and simplicity in use.
The instrument consists of a base plate, panel holder with clamp, a series of mandrels and the handle/bending mechanism. The base should be secured to a suitable work surface, allowing the operator to turn the handle smoothly during a test. The diameter of the mandrel to be used depends upon the test specifications
The Digital Krebs Viscometer is used for measuring the viscosity of Newtonian and non-Newtonian fluids. The viscosity of a non- Newtonian material varies depending on the rate of shear, but the Krebs viscometer measures the viscosity at a set speed shear rate which provides a consistent standard. The dimensions of the paddle conform to the precise specification of ASTM D562.
The Rotothinner is a robustly constructed instrument, which is easy to use, clean and maintain. Three models are available: a disc shaped rotor (Ref 455N/15) allows for the addition of thinners so that test samples can be adjusted to their correct viscosity and for the rapid adjustment of production batches; two ball shaped rotors (Ref 455N/65 & 455N/340) may be used for more viscous samples and for the addition of thinners more slowly.
The information of surface or the interfacial tension is critically important in applications such as detergency and emulsification and is also important for many biological processes. Especially, the Du NÕuy Ring method and the Wihelmy Plate method are commonly used for measuring surface / interfacial tensions.
The test consists of placing a small volume of product on the deep end and drawing it with a straight scraper toward the shallow end. The position on the scale where oversize particles and their tracks appear can be rated for determination of dispersion.
Flow cups, originally designed to perform quick viscosity and consistency evaluations of Newtonian or near non-Newtonian products, can provide a high degree of accuracy and repeatability depending on the quality of their manufacture
NHG268 gloss meter features with 20, 60 and 85° angle, manufactured according to ISO2813 and GB/T 9754. It is also compatible with the standards of ASTM D523, ASTM D2457. NHG268 conforms to JJG696 first class gloss meter working requirement, corresponding with CIE 1931(2°) under CIE C light source.
