Determination of Volatile Content of Coatings by Rapid Loss-On-Drying Instrumentation

4 Dec 2013

Paint is a three component material made of a pigment, a vehicle, and carrier. To ensure that they have the right blend of components a manufacturer will run loss on drying assays, which examines the amount of material that will volatilize once it is heated. This white paper compares two methods for testing paints and coatings and found rapid loss-on-drying methods prove to be more desirable than traditional testing methods.

Particle CharacterizationParticle characterization instruments are used to determine particle size distribution, shape, surface area, zeta potential, density and porosity of particles and materials. Multiple tecchniques are available for determining particle size, shape and count including dynamic light scattering (DLS), laser diffraction, electrozone (Coulter technique), imaging particle analysis and single particle optical sensing. Determine the density of your material with a gas pycnometer or examine its surface area and porosity with gas adsorption analyzers and mercury porosimeters. Find the best particle characterization instruments in our peer-reviewed product directory: compare products, check customer reviews and receive pricing direct from manufacturers.VolatilesVolatiles are a group of compounds that have a low boiling point and evaporate at room temperature. Volatiles, such as volatile organic compounds (VOCs), can be used to determine shelf-life of food samples. GC-MS is typically used to analyze volatiles.Metrology
