Contact Angle Test

Product Name Contact Angle Test Product Overview English Introduction: Contact angle test is a core characterization technology for evaluating material surface wettability, hydrophobicity and hydrophilicity, surface interfacial tension, surface cleanliness and interfacial bonding ability. It is an essential test method for material surface modification, coating research and development, powder wettability analysis and interface mechanism research of composite materials. By observing the spreading morphology of test droplets on the material surface through micro-optical imaging, the droplet contour is accurately fitted to calculate key parameters such as static contact angle, dynamic contact angle and surface free energy, which can directly evaluate the interface properties of materials such as hydrophobicity, hydrophilicity, antifouling, wettability and adsorption. It is widely used in polymer materials, functional powder materials, coatings and films, new energy materials, inorganic fillers and biomedical materials. Equipped with Swedish Biolin Theta Flex high-precision optical contact angle measuring instrument, this testing service features high imaging resolution, accurate fitting algorithm and excellent test stability. It is suitable for the surface wettability test of powder materials, and standardized testing can be completed with at least 100mg powder samples. The test data is accurate and reliable, complying with general industrial test standards, and can be directly used for scientific paper publication, surface modification mechanism demonstration, product hydrophobic and hydrophilic performance calibration, formula process optimization and enterprise quality inspection reports.
