ShanghaiApril 28, 2026 /PRNewswire/ — From April 22 to 24, the 8th MF High-Aesthetic, High-Performance Coatings Summit was held in Changzhou, Jiangsu Province. During the summit, a parallel forum titled “Construction Machinery & Undercarriage Parts — Overseas Exports: Coating Quality and Control” was concurrently held, bringing together leading OEM manufacturers, component suppliers, and seasoned coating technology experts to exchange technical insights on surface protection for construction machinery exports. Nippon Paint was invited to attend, addressing the dual challenges of corrosion resistance and environmental compliance for agricultural and construction equipment (ACE) exports, and sharing green, high-performance anti-corrosion coating solutions ranging from complete machine painting to localized touch-ups, providing innovative technological support for the global expansion of “Made in China.”
Liu Yi, Sales Director of ACE Industry, Industrial Coatings Division, Nippon Paint China Industrial Coatings Business Group, delivers a keynote presentation
Currently, China’s agricultural and construction machinery industry is undergoing a new wave of global expansion. The overseas business share of leading companies has generally exceeded 50%, with export destinations rapidly extending from traditional Southeast Asia and Africa to the Middle East, Europe, and South America. These emerging markets often feature complex environments such as high salt spray, strong UV radiation, and significant temperature fluctuations. Coupled with salt erosion during weeks-long sea transport, equipment coatings face unprecedented challenges. At the same time, domestic environmental standards for industrial coatings[1] are continuously tightening, and export-oriented companies urgently need coating solutions that balance long-term corrosion resistance with green cost reduction.
Nippon Paint’s green, high-performance anti-corrosion coating solutions cover complete machines and localized areas, providing long-term corrosion protection for exported equipment in harsh environments such as high salt, high humidity, and large temperature differences
In response to the harsh marine environments along the Mediterranean coast, as well as the higher requirements for complete machine protection in extreme operating conditions such as mines, ports, and coastal areas, Nippon Paint has launched a dual-coat high-corrosion-resistant primer. When used with a specialized topcoat, this product innovatively simplifies the traditional three-coat system into a dual-coat system, reducing film thickness by approximately 60% compared to conventional solutions. It achieves salt spray resistance of up to 1,800 hours, equivalent to approximately 25 years of long-term corrosion protection, far exceeding the industry mainstream level of about 20 years[2], delivering a leap in corrosion resistance performance through technological innovation. In terms of process, it streamlines from “three coats, three bakes” to “two coats, one bake,” eliminating one coating and two baking steps, effectively improving construction efficiency while achieving a reduction in volatile organic compound (VOC) emissions by approximately 60% and a decrease in construction costs by about 50%, offering green economic benefits.
Before equipment leaves the factory, long-term rust prevention in coating blind spots such as machined surfaces, screw holes, and cable clips, as well as rapid repair of damage at bolt joints after sea arrival, are also practical pain points for exported equipment. Nippon Paint has specifically introduced a bake-free, self-spraying, high-corrosion-resistant repair varnish, featuring an innovative “two-component self-spray can” design with a dual-chamber can: The two components mix and cure instantly upon spraying. Compared to traditional single-component products, it forms a denser protective layer, providing corrosion protection for over 6 years, more than four times that of conventional single-component products in the industry[2], with weather resistance exceeding 1,000 hours. Thanks to the self-spray can format, construction personnel do not need specialized equipment; simply pressing the nozzle allows for easy spraying, making it particularly convenient and efficient in hard-to-reach areas like bolts and joints. The product can achieve surface drying in as little as 20 minutes at room temperature, requiring no baking throughout the process. It can be pre-sprayed on vulnerable parts before leaving the factory to form a barrier against marine corrosion, or used for rapid on-site repair overseas, preventing rust streaks at the source. This innovative solution achieves factory-grade protection quality with minimal construction effort, significantly reducing the lifecycle maintenance costs of exported equipment.
In accelerated corrosion tests simulating a marine atmospheric environment in the lab, Nippon Paint’s bake-free, self-spraying, high-corrosion-resistant repair varnish (left) remains intact and rust-free after over 600 hours, while the traditional varnish (right) shows significant rust after just 120 hours
Currently, both products are undergoing application testing at several leading industry companies. In response to the growing export demand of China’s agricultural and construction machinery industry, Nippon Paint will continue to increase R&D investment, providing customers with green, high-performance coating solutions covering the entire product lifecycle, safeguarding the global journey of “Made in China” with systematic innovative technology.
