How to Quantify Orange Peel

What is Orange Peel

Uneven film formation with hills and valleys in paint resembling the skin of an orange is know as Orange peel. It is a certain kind of finish that may develop on painted cast surfaces, screen protectors.

This texture distorts reflected light, causing reflected images to become fuzzy.

The potential causes of orange peel are:

1. Improper application technique where the spray gun is too close to the surface or the air pressure is too low for proper atomization of the paint.
2. Hot air temperatures may also cause this defect because paint droplets dry before they can flow out and level smoothly together.
3. Incorrect cure temperature and time
4. Coating viscosity too low or too high
5. Incorrect particle distribution and size

To quantify orange peel accurately and consistently require instruments such as Rhopoint IQ-S. This instrument provides user with measurement parameters such as Distinctness of Image (DOI) and Reflected Image Quality (RIQ) that can measure and evaluate orange peel objectively.
