A New Evaluation Method for the Persistence of Liquid Films (Foam Films) Using a Surface Tension Meter: Possibilities for Application in Coating Film Quality Assessment.
A new evaluation method for liquid membranes as an alternative to lamella length measurement has been devised! - Available as an option for the DyneMaster series of surface tension meters. - This evaluation method serves as an effective means for cases where clear differences exist in sensory evaluations, but differences are not easily visible in surface tension or lamella length measurements, making quantitative assessment difficult. - For other features and details, please download the catalog or contact us. *For more information, please refer to the PDF materials or feel free to contact us.

Company information
Our contact angle meters and surface tension meters have a wealth of delivery records and publications. We also provide equipment related to interfaces, such as friction meters, zeta potential meters, adhesive film peeling analysis devices, and LB film production devices, contributing multifacetedly to our customers' research, development, and quality control. ★ We accept commissioned measurements. Our commissioned measurements utilize high-performance equipment, and dedicated measurement personnel handle everything from measurement to reporting. We strive to provide reliable data that serves as evaluation criteria for material assessment. - Static/Dynamic/Contact Angle (wetting properties, liquid repellency, cleaning evaluation, surface free energy analysis) - Static/Dynamic Surface and Interfacial Tension (permeability, emulsification, solubility, wettability, foaming) - Lamella Length (foam stability, coating pickup, liquid drainage, wicking evaluation) - Powder Wettability (wettability of powders, wettability due to surface treatment and roughness of powders, wettability evaluation based on powder penetration speed) - Static/Dynamic Friction Wear Analysis (friction wear, lubricity, stickiness, slip properties) - Tensile Testing (adhesion, angle dependence, light peeling, high-speed peeling) - Zeta Potential (particle size distribution, dispersion stability, aggregation, sedimentation) - Anti-fogging Evaluation (degree of fogging, transparency, condensation)
