Here are common causes of solvent popping: Temperature: High oven temperatures heat wet film too quickly, causing the solvent to vaporize. Film cannot flow into resulting voids fast enough. Solvent Blend: Too much low-boiling solvent (thinner) may cause popping during flash or upon entering the oven.

What are fisheyes typically caused by?

Fisheyes are small crater-like openings in the refinish material. It is caused by a contaminated area on a panel that repels refinish materials. They typically appear in wet material and can be seen in one small spot or several areas.

What Causes Solvent Pop And Fisheye in Automotive Paint?

Why does paint look like orange peel?

What is the orange peel effect in paint? The name orange peel is given by the resemblance of the final paint finish to an orange peel. This problem is caused by the lack of stretching or levelling of the paint, resulting in a deformed surface and in an increased thickness of the final coat.

How do you prevent fisheye in paint?

Thoroughly clean the surface to be painted with detergent and hot water, followed by the recommended solvent cleaner. Wipe dry with clean rags. Install an air filtering system that removes and prevents oil and moisture contamination. Maintain air supply by draining, cleaning and changing filter(s) on a routine basis.

What causes fish eyes in epoxy?

When a coating is applied to a substrate that is contaminated with low surface energy particles such as oil, wax, grease, or silicone, fish eyes may develop in the coating as it is applied. These fish eyes are produced because the coating is unable to wet out the contaminated area.

What causes fisheye in powder coating?

A fair amount of the time, fisheyes are caused by contaminants like oil, silicone, or water; either in the powder itself, on the substrate, or contaminating both during application. Oil and silicone are particularly notorious for causing fisheyes.

What causes fish eyes in drywall mud?

Evaporation is the most important factor to consider when choosing your solvent. If it evaporates too quickly, the surface of the paint may wrinkle or a haze may form. If it evaporates too slowly, the paint could seal with the solvent trapped underneath, creating bubbles and blisters.

What are some possible causes of dry spray?

Dry Spray

• Viscosity of paint too high, use of incorrect or poor quality thinner.
• Poor spraying technique, dirty spray gun, compressed air pressure too high, gun held too far from the surface during spraying.
• Spraying in draughts or in a high velocity airflow.
