How to Choose a Rotational Viscometer for Coatings and Inks: A Buyer’s Checklist
Why Does Viscosity Control Matter for Coatings and Inks? Viscosity determines whether a coating applies smoothly, levels properly, or sags. It is not a fixed



Explore selected material testing equipment for viscosity, weathering, corrosion, and other laboratory testing applications across paints, coatings, inks, plastics, and related materials.

BGD 182 Cone-and-plate Viscometer uses a special angle conical spindle, which generates a very high shear rate on the measured sample under the high-speed drive of a stepper motor. It conforms to ISO 2884-1《Paints and varnishes — Determination of viscosity using rotary viscometers — Part 1: Cone-and-plate viscometer operated at a high rate of shear》.

BGD 855 & 856 UV Light Accelerated Weathering Tester(hereinafter referred as BUV)adopts fluorescent UV lamp as the light source. Its inner temperature and humidity can be properly controlled to obtain the periodic condensation on the sample for fully evaluating the damaged factor caused by sunlight, moisture and temperature (materials aging phenomenon includes fading, gloss loss, intensity reduction, cracking, flaking, chalking, and oxidation).

Cyclic Corrosion Test Cabinets combine salt spray, humidity, and drying in one chamber. Programmed cycles simulate the outdoors. The instrument also conducts NSS, AASS, CASS, water spray, damp heat, and drying tests.

BGD 862 Plus is a multi-function big xenon light accelerated weathering testers which is equipped with one piece high power(6.5KW)water-cooling xenon lamp, its exposure area arrive 6,500cm²

Viscosity testing becomes useful when the method matches how a coating or ink behaves during processing. Sample type, expected viscosity range, spindle geometry, test speed,
Long-term laboratory performance depends on more than the purchase of a single instrument. R&D, quality-control, and procurement teams need to evaluate whether a supplier can
A reliable coating and materials laboratory depends on suitable instruments, clear testing procedures, and consistent data management. R&D teams, quality-control departments, and procurement managers need

As a core member of ISO TC35 and TC61, BIUGED has led the drafting and revision of 80+ national and industry standards—including two as primary drafting company—shaping the future of material testing across 80+ countries.
