What is a Contact angle meter?

A contact angle meter is a device used to measure the contact angle formed when a liquid droplet interacts with a solid surface. The contact angle is a critical parameter for evaluating surface energy and wettability between solids and liquids. This data is essential in fields such as material science, surface treatment technology, coatings, and semiconductor manufacturing. Applications include assessing the performance of water-repellent coatings, verifying adhesive suitability, and evaluating surface modification effects. Contact angle meters typically feature high measurement accuracy, capturing droplet shapes with a camera and analyzing them using dedicated software.

Application of Contact angle meter

✅Evaluation of Water-Repellent Coatings
Contact angle meters assess how well a water-repellent coating repels water. A high contact angle indicates superior repellency.
✅Adhesive Suitability Testing
Measuring the contact angle helps evaluate how well an adhesive bonds to a specific surface, predicting bonding strength.
✅Surface Treatment Verification in Semiconductor Manufacturing
Contact angles are measured to confirm the hydrophilic or hydrophobic nature of wafer surfaces, ensuring quality control during production.
✅Ink Penetration Assessment
In the printing industry, the contact angle evaluates how uniformly ink spreads on a material surface, enhancing print quality.
