Our Contact Angle Measurement Services

Precision Analysis for Critical Insights

Our contact angle measurements provide detailed insights into the liquid-solid interface. By placing a small droplet of liquid on a surface and analyzing the resulting contact angle, we can determine the surface’s wettability and energy properties. This information is essential for optimizing material performance and ensuring successful application in various industries.

Comprehensive Surface Energy Evaluation

Using different liquids such as water, ethylene glycol, and diiodomethane, we measure both polar and dispersive surface tension values. This comprehensive evaluation helps in:

• Adhesion Optimization: Ensuring coatings and adhesives bond effectively.
• Surface Treatment Verification: Confirming that treatments have achieved the desired surface chemistry.
• Cleanliness Testing: Detecting contamination that might affect surface properties.

Dynamic Measurement Capabilities

Our contact angle instrumentation captures the interaction between liquid droplets and surfaces at 60 frames per second, allowing us to monitor dynamic changes in surface properties over time. This capability is vital for understanding how materials behave under different conditions and over extended periods.

Real-World Applications

Ensuring Adhesion and Coating Performance

The surface energy of materials directly impacts the performance of adhesives and coatings. Our contact angle measurements help manufacturers select the best materials and processes to achieve optimal adhesion and durability.

Verifying Surface Treatments

Surface treatments like corona treatment or plasma treatment can significantly alter surface properties. By measuring contact angles before and after treatment, we ensure that the desired modifications have been successfully implemented.

Cleanliness and Quality Control

In industries where surface cleanliness is critical, such as semiconductor manufacturing or biomedical device production, our contact angle measurements provide a reliable test for verifying that surfaces are free from contaminants.

Advanced Analytical Techniques

State-of-the-Art Equipment

We use a high-precision syringe to apply liquid droplets, and a microscope with camera captures detailed images. These images are analyzed using sophisticated software to calculate contact angles with high accuracy.
