Automotive putty 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 car 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 Atomic Putty 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.

Sistem produk:dempul automotifis a complete coating system — not a single product. It includes: ① Epoxy Primer (provides adhesion + rust prevention, suitable for carbon steel/galvanized sheet/aluminum alloy/plastic substrates) → ② PU Primer-Surfacer (fills sanding marks and micro-pinholes after putty sanding, provides a smooth substrate) → ③ Basecoat/Topcoat (solid/metallic/pearl three series, providing color and decorative effects) → ④ 2K High-Solids Clearcoat (protective clear coating + mirror gloss DOI>90, aliphatic curing agent for non-yellowing). Intercoat adhesion Class 0 (cross-cut ISO 2409). The 2K system forms a three-dimensional network structure through isocyanate-hydroxyl crosslinking — the cured coating resists gasoline/engine oil/brake fluid/cleaner (24h each, no abnormality).

Latar belakang industri: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 putty 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 stores). Kexin water-based automotive putty series has VOC...<100g/L——Meets最严格的地方Alam sekitarstandard。

快速干燥

3. Quick drying, shortening delivery cycle

Pembakaran pada 60°C selama 30 minit mempercepat pengerasan — klearkoat boleh dipoles selepas itu. Pada suhu bilik (23°C) kering sentuh dalam ≤30 minit dan kering penuh dalam ≤4 jam — pembaikan ekspres «sembur pagi, serah petang». Formulasi klearkoat kering cepat boleh dipoles 2-4 jam selepas semburan tanpa melekat pada pad. Ini kritikal bagi dealer 4S dan rantaian pembaikan laju: masa penyerahan mengecut daripada 2-3 hari (cat konvensional) kepada dalam satu hari.

4. Complete package, one-stop supply

Dari putty panel → primer epoksi → surfacer PU → basecoat → klearkoat 2K — sistem padanan lengkap dibekalkan oleh Kexin. Lekitan antara lapisan gred 0 (ISO 2409) — cat semula tanpa pengampasan. Serasi juga dengan produk setara jenama utama (BASF Glasurit/PPG Nexa Autocolor/Axalta Spies Hecker) — dealer 4S boleh menukar pembekal tanpa mengubah proses.

6. Suitable for multiple substrates; excellent adhesion.

Primer epoksi mencapai lekitan gred 0 pada banyak substrat biasa dalam pembuatan automotif: keluli karbon, kepingan galvani, aloi aluminium dan plastik (PP/ABS/PC). Primer PP khas untuk bom plastik boleh disembur terus tanpa rawatan nyalaan/korona. Untuk badan aluminium (kian umum pada kenderaan tenaga baharu) — epoksi + surfacer PU + basecoat + klearkoat — sistem lengkap memberikan lekitan gred 0.

Application Process

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

Penyemburan saliran warna

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

salut kilau klare

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.

FAQ

Sering DitanyaSoalan lazim

Cat kilang perlu dibakar pada 140-160°C selama 20-30 minit untuk mengeras sepenuhnya — kerana di talian OEM badan cuma kerangka logam kosong (tanpa kusyen, elektronik, tayar) dan boleh masuk ketuhar suhu tinggi. Cat pembaikan pula mesti mengeras pada suhu rendah (60°C atau suhu bilik) — kerana kenderaan lengkap (kusyen, elektronik, talian bahan api) tidak boleh terdedah melebihi 80°C. Oleh itu cat pembaikan menggunakan pengeras yang lebih reaktif secara kimia (trimer HDI taut silang pantas) — mencapai kekerasan/lekitan/ketahanan cuara setara cat kilang pada suhu lebih rendah. Formulasinya direka khusus — matlamat: “turunkan suhu pengerasan 100°C tanpa hilang prestasi”.
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Punca utama：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pes aluminium排列受Salutan semburan手法影响（Tekanan udara / jarak semburan / kelajuan pistol改变pes aluminiumOrientasi→影响随角异色Effect）；③车身旧漆因UV老化已变色（Merah/Kuning最明显）——Penyambungan semula (retouch)时需刻意微调Padanan warna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
Advantages of water-based paint: ① VOC<100g/L——Meets北京/上海/深圳等城市禁止4S DealershipPenggunaanSolvent typeRepair paint的Alam sekitar法规（法规驱动是最大因素）；②Metal漆/珍珠漆的Color鲜艳度和随角异色EffectSuperior ToSolvent type——尤其UntukPremium车（奔驰/宝马）的Metal漆——water-based paint的pes aluminium排列更seragam；③不Mudah terbakar——water-based paint不属Bahaya品（UN1263豁免）——penyimpanan/PengangkutanKos更Rendah.Solvent type漆的Kelebihan：①Application宽容度大——对温HumidityRendah（water-based paintRH>① Drying is extremely slow at 75% concentration; ② Drying is fast – solvent-based paints can be flash-dried in 5-10 minutes before applying a clear coat, while water-based paints require 15-20 minutes plus infrared pre-drying; ③ Minimal investment in retrofitting existing equipment (solvent-based equipment can be used directly). 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.
