Product Overview

ProductsOverview

The heavy-duty anti-corrosion coating system is a heavy-duty anti-corrosion paint designed by Kexin New Materials in accordance with the ISO 12944 standard. It is scientifically formulated with high-quality resins and high-performance anti-rust pigments, offering excellent corrosion resistance and adhesion. It is widely used for protective coating in heavy-duty anti-corrosion fields such as steel structures, bridges, petrochemicals, and ships.

The product has passed rigorous salt spray testing (>1000h) and adhesion testing (>5MPa), and with a complete base-intermediate-topcoat system, it can provide long-lasting protection for 15-25 years. Kexin provides free coating design solutions and technical support services.

Product highlights

CoreAdvantages

One-stop coating system solutions

The customer's coating engineer customizes the optimal coating system solution based on project parameters such as corrosion environment (ISO 12944 C2-CX), design life (5-25 years), substrate type, and application conditions. A full range of coating products and construction process guidance is provided to eliminate customer selection difficulties.

ISO 12944 international standard design

Designed in accordance with the international standard ISO 12944 "Corrosion protection of steel structures by protective paint systems". The coating system is designed based on atmospheric corrosivity categories (C1-CX), immersion categories (Im1-Im4), and soil categories. A coating system solution with a 25-year design life is provided to meet the durability requirements of major projects.

Technical support for major projects

Full-process technical support from coating system selection/sample preparation/process parameter determination/on-site construction guidance/quality inspection and acceptance. Kexin coating engineers can provide on-site services to ensure coating quality. Cooperate with project supervisors and owners for third-party inspection and verification of coating quality.

Professional coating technology support services

Kexin has an experienced coatings R&D and applications team that supports the whole process - substrate analysis, coating selection, optimisation of process parameters and on-site application guidance. Our engineers commission the coating parameters on your own production line so that finish quality and output are both optimised.

Eco-compliant green manufacturing system

All products are RoHS/REACH compliant and their VOC content meets national environmental standards. Waterborne and high-solids low-VOC formulations are continuously refined to keep pace with ever stricter environmental requirements. Environmental performance test reports issued by third-party authorities such as SGS and CTI are available on request.

Complete quality control and batch traceability

A quality-control system covering the whole process, from incoming raw materials to finished-goods dispatch. Every batch undergoes rigorous physico-chemical testing and simulated application trials. Batch numbers are traceable end to end, so raw-material sources and production data can be retrieved. Each shipment is released with a batch test report and a product warranty, so customers can use it with confidence.

FAQ

Frequently AskedFAQ

Which substrates does it suit?+

Suitable for sandblasting and rust removal up to Sa2.5 grade on carbon steel and cast iron surfaces. The substrate must be free of oil, rust, and old paint; a roughness of Rz40-75μm is optimal.

Why can't it be left exposed?+

Epoxy is not UV-resistant and chalks under long exposure. It must be paired with an epoxy MIO intermediate coat and a weather-resistant topcoat to form a complete system.

Which primer or topcoat completes the system?+

We recommend using a matching primer and topcoat from the same Kexin series to secure system compatibility and best performance. A Kexin engineer can design a complete primer-midcoat-topcoat system for your specific service conditions, free of charge.

How to get samples and a quote?+

Free samples of standard products are provided (freight at the customer's cost), supplied with TDS and MSDS documentation. For bulk purchases please contact 400-901-0757 or 13531350189. Sample quantity from 1 kg; bulk orders from 20 kg.

How do I pick the right grade for my operating conditions?+

Choosing a coating product requires considering the substrate type, the service environment (temperature / humidity / chemical media), the required corrosion protection class (ISO 12944 C1-C5M), the application conditions and the budget. We recommend contacting our technical engineer on 400-901-0757 for professional selection advice; free trial spraying and test verification are supported.

What is the MOQ and lead time?+

Samples from 1 kg; regular products from 20 kg per batch. Stock items ship within 48 hours, made-to-order products in 3-7 working days. Door delivery can be arranged within the Pearl River Delta region.

Application guide

ApplicationProcess

Surface preparation

Clean substrates thoroughly of oil and rust. Blast steel to Sa2.5. Pre-treat per product spec to keep the substrate clean. Ambient 5-40°C, relative humidity<85%。

Primer / pre-treatment

Select the matching primer or pre-treatment per substrate and system. Mix strictly at the stated ratio and control DFT. Proceed after the primer dries; pre-stripe critical areas.

Main-coat application

Apply the main coat per the process spec, strictly controlling DFT, temperature/humidity and flash-off to keep the film uniform without sagging or pinholes.

Curing process

Cure fully by stoving or by ambient air drying as the product requires. Keep oven temperature uniform within ±5°C and ramp up gradually to avoid coating defects. For ambient-curing grades, ensure adequate ventilation and suitable humidity.

Inspection & acceptance

Inspect all parameters: dry film thickness, adhesion, gloss, colour difference and chemical resistance. Full performance testing is carried out against the relevant standards. Only after everything passes are the test report and warranty issued, and the goods are packed and shipped in dust-free conditions.
