Guess the Contact Angle: IPA Wiped Composite Material

This 'Guess the Contact Angle' video is the first of our next series of videos focusing on how contact angle changes when a composite surface is cleaned or treated in various ways. 

The contact angle featured in this demo is formed by a water droplet deposited using the handheld Surface Analyst on a piece of composite material.

Can you guess the contact angle?

How did you do?

Remember, there is no single “best” value for a contact angle. The ideal water contact angle measurement will depend on your particular processes and applications.

Rethink your adhesion manufacturing processes with Surface Intelligence.

Previously Featured - Guess the Contact Angle: Aluminum Material Surface

Our previous Guess the Contact Angle Series focused on demonstrating contact angle variations when a series of cleaning and treatment processes are performed on an aluminum sample: 

1. The first video demonstrates the Surface Analyst taking a contact angle measurement on a piece of aged, 'as is' aluminum.
2. The second video asks you to guess the contact angle after cleaning the 'as is' aluminum sample using an IPA wipe.
3. The third video shows how contact angle changes (surface quality) when we take the same aluminum sample, clean it, and then abrade the surface.
4. The fourth video demonstrates how the contact angle changes when aluminum is treated using atmospheric plasma.

Why is Contact Angle Important?

Adhesion, coating, and cleaning are critical manufacturing processes. The Surface Analyst line of products leverages our deep experience in surface engineering and materials science to validate any surface for cleanliness and guarantee reliable adhesion.

Struggling with adhesion failures? Been there. Solved that.
