پروڈکٹ کا جائزہ: کس کے لیے؟ کون سا مسئلہ حل کرتا ہے؟

Automotive clear coat is an aftermarket repair coating that provides 4S stores, comprehensive auto repair shops, and body and paint centers with the same appearance quality as the original factory paint.The core problem it solves is that after a car is repaired due to a collision/scratch, the color, gloss, and texture of the repaired area must be completely identical to the original paint (no color difference) – meaning that non-automotive paint professionals simply cannot distinguish the repair marks. Kexin Automotive Clear Coat System precisely matches the original manufacturer's color code (OEM Color Code), ΔE<1.0(CIELABColor Difference公式,人眼无法分辨),DOI>85 (meets automotive Class A surface standards), 60°C x 30 min rapid curing – helps repair shops shorten delivery time from 3 days to 1 day.

پروڈکٹ سسٹم:Automotive clear coat is a complete coating system—not a single product. It includes: ① Epoxy primer (provides adhesion + rust prevention, suitable for multiple substrates such as carbon steel, galvanized sheet, aluminum alloy, and plastic) → ② PU intermediate primer/surfacer (fills sanding marks and micro-pinholes left after putty sanding, providing a smooth base) → ③ Color coat/topcoat (available in three series: solid color, metallic flash, and pearl, offering color and decorative effects) → ④ 2K high-solid clear coat (provides protective overcoating + mirror-like gloss with DOI > 90, using aliphatic hardener to prevent yellowing). The adhesion between each layer is Grade 0 (cross-cut test per ISO 2409). The 2K system forms a three-dimensional network structure through the cross-linking reaction between isocyanate and hydroxyl groups—the cured coating is resistant to gasoline, engine oil, brake fluid, and cleaning agents (no abnormalities after 24 hours of exposure to each).

صنعتی پس منظر:According to statistics from the China Association of Automobile Manufacturers, China's car ownership reached 340 million vehicles in 2024—resulting in over 200 million bodywork repairs annually due to traffic accidents and scratches. The automotive clear coat market is approximately 12 billion yuan per year. Traditional solvent-based repair paints have VOC levels exceeding 500g/L—environmental restrictions have been implemented in many regions (Beijing, Shanghai, and Shenzhen have banned the use of solvent-based repair paints in 4S dealerships). Kexin water-based automotive clear coat series has VOC...<100g/L——Meets最严格的地方Eco-FriendlyStandard。

1. Precise color matching based on original factory color code (ΔE)<1.0)

Using a computer-aided color matching system (X-Rite MA-5 spectrophotometer and color matching software), the color is precisely adjusted according to the original OEM color code of the automobile—ΔE.<1.0(CIELABStandard,D65/10°光源)。覆盖全球主流Brand(奔驰/宝马/奥迪/大众/丰田/本田/通用/福特等)近10年的ColorFormulaDatabase——含素色/میٹل فلیش/珍珠三大رنگوں کی رینج,30000+Formula。Metal漆的随角异色Effect(Flop Index)通过ایلومینیم پیسٹ/云母珠光颜料ذرے کا سائز和排列控制——Ensures与车身原漆在任何观察角度下无Color Difference。

3. Quick drying, shortening delivery cycle

Baking at 60°C for 30 minutes accelerates curing—the clear coat is polishable. At room temperature (23°C), it's surface dry in ≤30 minutes and fully dry in ≤4 hours—allowing for "morning application, afternoon delivery" repairs. The fast-drying clear coat formula allows for polishing 2-4 hours after application—it doesn't stick to polishing pads. This feature is crucial for 4S dealerships and fast-repair chains—reducing delivery time from 2-3 days for traditional paint repairs to less than 1 day.

4. Complete package, one-stop supply

From sheet metal putty → epoxy primer → PU intermediate primer → color paint → 2K clear coat — all provided as a complete system by Kexin. Interlayer adhesion between each layer is Grade 0 (ISO 2409) — recoating is possible without sanding. It is also compatible with similar products from mainstream brands (BASF Glasurit/PPG Nexa Autocolor/Axalta Spies Hecker) — 4S shops can flexibly switch suppliers without changing the process flow.

6. Suitable for multiple substrates; excellent adhesion.

Epoxy primer exhibits a 0-level adhesion rating on various commonly used automotive substrates, including carbon steel, galvanized sheet, aluminum alloy, and plastics (PP/ABS/PC). A PP primer specifically for plastic bumpers can be directly applied without flame or corona treatment. For aluminum alloy car bodies (due to the increasing prevalence of new energy vehicles), a complete set of epoxy primer + PU intermediate coat + color coat + clear coat achieves a 0-level adhesion rating.

ApplicationProcess

1

Sheet metal repair + cleaning

Sheet metal repair → Grinding feathered edges (P80-P180) → Cleaning and degreasing (degreaser + dust cloth). Bare metal areas need to be sprayed with epoxy primer for rust prevention. Plastic parts are treated with PP primer.

2

Atomic putty + intermediate primer

Apply unsaturated polyester putty to the recessed area (sanding can be done after 20-30 minutes) → sand smooth in stages from P180 to P320 → spray 2-3 coats of PU intermediate primer → wet sand at P400-P600 after drying.

3

بیس کوٹ اسپرے

Accurately weigh and mix the color according to the formula → apply 2-3 coats of color paint (with a 5-10 minute flash-dry interval between each coat) → spray the solid color paint directly → for metallic paint, control the spraying technique (air pressure/spray distance/gun speed) to ensure uniform aluminum powder distribution.

4

کلئیر گلوس اوور

2K high-solids clear varnish in 2 coats (first coat semi-wet → flash dry for 5-10 min → second coat fully wet) → bake at 60°C for 30 min to accelerate curing (or at room temperature for 12 h) → polish after drying.

5

Polishing + Inspection

P1500-P3000 sandpaper wet sanding to remove dust spots → three-step polishing with coarse wax + fine wax + mirror wax → inspection of DOI/gloss/color difference/adhesion → cleaning and delivery. Quality requirements: no color difference and no repair marks visible from a distance of 1m.

Original paint (OEM) requires baking at 140-160°C for 20-30 minutes to fully cure—this is because on the OEM painting line, the car body is just a metal shell (without interior/electronic components/tires) and can enter a high-temperature baking oven. However, refinish paint must cure at low temperatures (60°C or room temperature)—because the complete vehicle (including interior, electronics, and fuel lines) cannot withstand temperatures above 80°C. Therefore, refinish paint uses chemically more reactive hardeners (HDI trimer for rapid cross-linking)—achieving the same hardness, adhesion, and weather resistance as OEM paint at lower temperatures. The formulation of refinish paint is specifically designed with the goal of "reducing the curing temperature by 100°C without compromising performance."
Accurate matching steps: ① Find the vehicle body color code (usually on the label in the engine compartment/door frame/B-pillar, such as "197U" for Mercedes-Benz and "A96" for BMW); ② Enter the code into the customer information color database → the system provides the formula (including the proportions of all color masterbatches); ③ Prepare a 50g sample → compare it with the vehicle body under standard lighting (D65) and side lighting (A light source); ④ If minor adjustments are needed → use color matching software to calculate the correction amount → re-mix → until ΔE is achieved.<1.0。Color Difference产生的主要اسباب:①不同批次Original paint本身有微小Color Difference(OEM允许ΔE<2.0的批次差异);②Metal漆的ایلومینیم پیسٹ排列受Spraying手法影响(ایئر پریشر/اسپرے فاصلہ/گن اسپیڈ改变ایلومینیم پیسٹ取向→影响随角异色Effect);③车身旧漆因UV老化已变色(سرخ/پیلا最明显)——Refinishing时需刻意微调رنگ کی مطابقت已老化车身。
1K clear coat = single-component, relies on solvent evaporation for physical drying—the coating merely "dries" without undergoing chemical crosslinking—resulting in poor solvent resistance, hardness, and durability (softens when exposed to gasoline). 2K clear coat = two-component (base + hardener), where isocyanate (-NCO) undergoes a chemical crosslinking reaction with hydroxyl (-OH) groups in the base—forming a three-dimensional network structure—so that even after curing, it does not soften when immersed in gasoline. The hardness of 2K clear coat (≥H vs. 1K's

Trend: The EU/North America has mandated water-based paints (driven by regulations), and first-tier cities in China are rapidly switching to this method.
