The Science Behind 3M™ Scotchgard™ Anti-Fog Technology
3M™ Scotchgard™ Anti-Fog Technology brings higher anti-fog performance to safety eyewear, helping workers see more clearly to complete on-the-job tasks. The anti-fogging properties are based on 3M internal testing per EN168 test method when compared to traditional anti-fog coatings.. Here is how the anti-fogging properties work. When microscopic water droplets land on lenses without any type of coating, they bead up and form condensation and fog, obscuring your vision. With 3M™ Scotchgard™ Anti-Fog Technology, the anti-fog coating produces a reduced-contact angle, flattening the water beads into a thin, transparent film of water that allows light to pass through. The Scotchgard™ Anti-Fog Coating resists fogging longer than traditional anti-fog coatings, even after washing multiple times.
