Скачать или смотреть Surface Tension - Automotive Coatings Technology - Vimal Kumar Gopi

Surface tension is one of the most critical yet misunderstood factors in automotive coatings technology.
In this video, we break down how surface tension controls paint wetting, flow, leveling, and appearance — and why even perfectly formulated paints can fail if surface tension is not balanced correctly.

You’ll learn:

What surface tension really means in automotive paints

The relationship between coating surface tension and substrate surface energy

Why defects like cratering, cissing, and poor wetting occur

How surface-control additives such as silicones and fluorinated additives work

Why lowering surface tension too much can also create appearance problems

This video is useful for:
Automotive coating engineers, paint technologists, quality engineers, applicators, and anyone working with OEM or refinish paint systems.

Whether you are troubleshooting defects on the paint line or trying to understand coating fundamentals, this video explains surface tension in a practical, real-world way.
