The Industry Challenge: Tackling Yellowing and Fading of Carbon Fiber Parts

Yellowing and loss of gloss on carbon fiber aftermarket parts have long troubled the industry. Whether in overseas markets or domestically, wholesalers and brand owners often face complaints related to product aging, yellowing, and premature discoloration. At JCSPORTLINE, we have invested heavily in R&D to improve the UV resistance and aging performance of carbon fiber surface resins. We understand that solving yellowing is key to guaranteeing both aesthetic appeal and long-term durability, providing peace of mind for our clients and their customers.

Does Carbon Fiber Really Turn Yellow?

Short answer: The carbon fiber itself is very stable and generally does not yellow. The real culprit is the protective resin or clear coat layer covering the carbon fiber: Traditional resins oxidize and yellow when exposed to UV, heat, and environmental contaminants Extended exposure to sunlight or engine bay heat causes softening, discoloration, and even cracking of the resin layer This resin degradation is what causes the visible yellowing and dulling, not the carbon fiber fabric itself

The Story Behind Our Anti-Yellowing Technology

A few years ago, a European wholesale client came to us frustrated: “I bought carbon fiber parts before that looked great at first, but less than a year later, they yellowed and became brittle after sun exposure. We had many returns and complaints. Can you make a more durable part?” We explained that the fiber is stable, but the resin is the weak link. To meet their demand, we: Selected imported epoxy resins with superior UV resistance Applied advanced heat-curing processes Used professional UV aging test chambers to simulate years of sun exposure When asked, “How long will it last?” we answered honestly: “While no product is guaranteed to never yellow, our parts undergo rigorous testing and show far better yellowing resistance than market averages—enough to confidently support your sales and satisfy your customers.” The results? This client significantly reduced returns and complaints, while steadily improving their brand reputation.

How to Prevent and Restore Carbon Fiber Yellowing

Depending on the severity of yellowing, JCSPORTLINE recommends different care solutions: Mild oxidation (surface haze, no cracks): Clean with neutral car wash soap and clay bar Wipe with alcohol or special cleaning agents Apply ceramic coating for 12–18 months of protection Moderate oxidation (localized yellowing, fine cracks): Sand the oxidized layer with 2000–3000 grit paper Apply high-temperature resin clear coat and polish Use professional ceramic coating products for repair Severe oxidation (large yellowed areas, resin cracking): Sand down to the carbon fiber base fabric and repair if necessary Reapply resin coatings with multiple spray and sanding cycles Preventative tips: Regular waxing with UV-blocking car wax Install professional TPU protective films Avoid prolonged parking in extreme heat Use car covers to protect from acid rain and pollutants
