{ "@context": "https://schema.org", "@type": "FAQPage", "mainEntity": [ {"@type":"Question","name":"How is orange peel formed?","acceptedAnswer":{"@type":"Answer","text":"After spraying, paint droplets should level out and flatten, but if the viscosity is high, atomization is insufficient, leveling time is inadequate, or the thinner evaporates too quickly, the droplets set before flattening, leaving orange-peel-like ripples."}}, {"@type":"Question","name":"How to improve orange peel?","acceptedAnswer":{"@type":"Answer","text":"Choose a suitable thinner by temperature zone to reduce viscosity, increase air pressure to ensure atomization, allow sufficient flash-off time between coats, and match the thinner evaporation rate to the environment; slight orange peel that has fully dried can be reduced by polishing."}}, {"@type":"Question","name":"Can wrong thinner choice cause orange peel?","acceptedAnswer":{"@type":"Answer","text":"Yes. A thinner that evaporates too quickly causes the paint droplet surface to skin over rapidly and not have time to level; too slow evaporation may cause sagging. Choose a thinner with a corresponding evaporation rate according to the application temperature."}}, {"@type":"Question","name":"Can orange peel be removed by polishing?","acceptedAnswer":{"@type":"Answer","text":"Mild orange peel can be significantly reduced by polishing after the paint film is fully cured; but severe orange peel is ripple at the film-thickness level, where polishing has limited effect, and re-spraying with adjusted application parameters is needed."}}, {"@type":"Question","name":"Is the flatter the better for orange peel?","acceptedAnswer":{"@type":"Answer","text":"No. Over-pursuing a mirror-flat finish often requires lowering viscosity and increasing film thickness, which may affect hiding power and sag resistance. Just control it within an acceptable range per the coating specifications."}} ] }
