Surface Treatment






The water-based UV coating system is adopted for the painting solution of Rear Brake Disc of Imported Lexus CT 4243102550. It is worth elaborating on the reason for choosing UV coatings: traditional solvent-based coatings require high-temperature baking for a long time, which leads to high energy consumption and high VOC emissions. In contrast, water-based UV coatings use water as the diluent without chemical solvents, greatly upgrading environmental performance. More importantly, UV coatings cure instantly under ultraviolet irradiation, delivering high production efficiency. In addition, the cured coating film boasts superior hardness and compactness compared with traditional baked coatings.
Spray painting may seem straightforward, yet achieving a flawless finish hinges entirely on attention to detail.
First, adhesion. We conduct cross-hatch adhesion tests for every production batch: a blade is used to score a grid pattern on the coating surface, specialized adhesive tape is applied and ripped off sharply, then the area of peeled coating is inspected. The required standard is ISO Grade 0 or 1, meaning clean-cut edges with peeling area no greater than 5%.
Next, salt spray resistance. Brake discs are highly susceptible to salt corrosion, especially when driven on roads treated with snow-melting agents in northern winters. Our UV paint coatings pass neutral salt spray testing, with a baseline requirement of zero red rust formation over 240 hours. What does this standard signify? It means the rust-proof service life of coated sections far exceeds that of ordinary uncoated iron discs under regular operating conditions.
Then there is high-temperature resistance. Temperatures on brake discs can soar above 300°C during frequent braking. Conventional paint would char and discolor at such temperatures, but our custom-formulated UV paint retains stable adhesion and undiminished anti-corrosion performance under high heat.
Last is stone chip resistance. Flying gravel striking disc surfaces is a common occurrence on roads. Our coatings comply with the stone-chip and salt spray combined test under ISO 20567-1. This test simulates harsh dual conditions of gravel impact plus salt spray corrosion, and the coatings remain intact without peeling or rusting.

FAQ
What special points should be noted when replacing the rear brake discs of the CT200h?
The CT200h is a hybrid vehicle equipped with an energy recovery function for its braking system, so replacing its brake discs differs from that of ordinary fuel-powered cars.
Here are several key points:
First, it is recommended to switch the vehicle into maintenance mode (some car owners refer to it as "invalid mode") before operation to prevent automatic system intervention.
Second, do not open the driver's side door during the operation, otherwise the braking system may be activated.
Third, if you plan to do the replacement yourself, you may disconnect the 12V battery and apply even force when pushing back the caliper pistons.
If you are unfamiliar with the braking system of hybrid vehicles, it is advised to entrust the operation to professional technicians.
Why choose the products from your factory? What are its advantages?
Our factory has been exporting brake discs for over a decade, and we have extensive experience in supplying parts for original equipment manufacturers. For the model 4243102550, the production process goes from raw materials to finished products through fully automated machining lines and dedicated closed-loop painting systems; each batch is inspected regarding coating thickness, dynamic balance, and end-face accuracy, with the relevant data being archived for traceability. The coating withstands salt spray tests, ensuring excellent rust resistance on the non-friction surfaces. Every brake disc that leaves our factory goes through all the required processing steps in accordance with uniform standards – there is no cutting corners, no use of inferior materials, and no compromises. Once installed in your vehicle, you will experience what it means to have reliable products.
Last News
In the current automotive aftermarket, the demand for high-carbon brake discs is growing rapidly, especially for hybrid vehicles like the Lexus CT. High-carbon alloys offer better heat dissipation and reduce the risk of cracking under heavy braking compared to standard grey iron. Additionally, anti-rust coatings are becoming an industry standard, as they not only improve aesthetics but also reduce warranty claims related to premature corrosion. Partnering with a supplier who integrates these advanced materials ensures your business stays ahead of market trends and meets the evolving expectations of safety-conscious consumers.
