Dynamic vs. Static Contact Angle Testing: Key Differences and Applications
Dynamic contact angle test measures liquid behavior during motion, providing advancing and receding angles that reveal surface roughness and contamination. Static testing measures equilibrium droplets for basic wettability characterization and quality control applications. Defining Static Contact Angle (Sessile Drop) Static contact angle testing is the foundation of surface wettability measurement. This test method captures how […]
A Step-by-Step Guide to the ASTM Contact Angle Test Method
The ASTM contact angle test involves preparing your sample, dispensing a water droplet, capturing an image, and measuring the contact angle using specialized software under controlled environmental conditions. Why are ASTM Standards Important for Contact Angle Measurement? ASTM standards establish consistent protocols that ensure reliable, comparable results across different laboratories and applications. The contact angle […]
