Introduction
Corrosion resistance is a critical factor in metal component design and longevity, especially for applications in the automotive, construction, agriculture, and heavy machinery sectors. Zintek 200, a premium silver zinc flake basecoat, delivers superior corrosion protection combined with robust adhesion and exceptional coverage. This solvent-based coating has been engineered to withstand intense environmental stress without hydrogen embrittlement, making it an optimal solution for high-demand parts such as fasteners, chassis components, and brake components. Moreover, the basecoat meets stringent standards set by major OEMs, including Volkswagen, Mercedes-Benz, and General Motors, ensuring compatibility and reliability across industries.
Lasting metal protection and aesthetic appeal
Zintek 200 is an inorganic silver zinc flake basecoat, specifically formulated for high-performance cathodic corrosion protection. During the application process, a conductive zinc-aluminum layer forms through baking, providing an effective sacrificial barrier. This layer serves as a continuous shield, mitigating oxidation and degradation of the substrate metal. The Zintek 200 basecoat is known for its adhesive strength and impact resistance. This ensures uniformity and resilience even under mechanical stress. It imparts an aesthetically appealing silver finish, making it suitable for visible components in various applications. The Zintek 200 basecoat process is free from harmful heavy metals, including hexavalent chromium (Cr(VI)), cadmium, cobalt, lead, nickel, and is now also available as non-PFAS containing version, minimizing environmental and health risks associated with these substances.
Cost-effective, high-yield coating
To ensure long-term protection in corrosive environments, the Zintek 200 basecoat was subjected to the ISO 9227 Neutral Salt Spray Testing (NSST), a standard accelerated corrosion test. Results indicate that two layers of Zintek 200 (with a total thickness of approximately 8 μm) can endure over 1,000 hours in NSST without visible signs of corrosion. This endurance level highlights the basecoat’s suitability for high-exposure environments, surpassing the performance benchmarks required for many industrial applications.
The Zintek 200 coating technology offers a high yield, providing an industry-leading coverage rate of 20 m²/kg at a 10 μm dry film thickness. This rate enables cost-effective application, allowing a single kilogram of Zintek 200 to cover significantly more surface area than comparable zinc flake base coats on the market.
The Zintek 200 coating is ideal for components across several high-stress sectors:
Automotive: Fasteners, chassis parts, springs, brake components, and clips benefit from enhanced durability and appearance, with the Zintek 200 basecoat’s resistance to mechanical and environmental stress.
Construction and heavy machinery: Components exposed to harsh outdoor conditions are well protected by the robust, corrosion resistant Zintek 200 basecoat layer.
Agriculture: Agricultural equipment, which frequently operates in corrosive soil and moisture-laden environments, gains long-term durability through this premium coating solution.
Leading coverage and durability, reducing costs compared to conventional zinc flake coatings
The silver zinc flake basecoat market offers a range of products with varying degrees of corrosion protection and cost-efficiency. Our Zintek 200 basecoat stands out due to its superior coverage rate and higher durability. With a theoretical coverage of 20 m²/kg (10 μm dry film), Zintek 200 delivers a lower cost per square meter of protected surface compared to alternative zinc flake coatings, which typically cover less surface area with the same quantity of material.
OEM compliance
Zintek 200 complies with key industry standards such as Volkswagen TL245 including VW 01131, Mercedes-Benz DBL 8440 including MBN50544, and General Motors GMW3359. These specifications set stringent requirements for corrosion resistance, coating performance, and environmental safety. Compliance with these standards ensures that Zintek 200 is approved for OEMs, making it a reliable choice for suppliers within the automotive and heavy machinery sectors. In addition to performance benefits, the basecoats lack of harmful heavy metals positions it as an environmentally responsible alternative to coatings containing substances like hexavalent chromium, cadmium, and lead. This compliance with modern environmental standards aligns with global sustainability goals, providing industries with a safer and more responsible option for corrosion protection.
The Zintek 200 basecoat offers a leading solution in zinc flake coatings, delivering superior corrosion protection, excellent adhesion, and best-in-class coverage. Its performance under ISO 9227 NSST, compliance with OEM standards, and environmentally safe composition make it a preferred choice for industries seeking reliable and sustainable protective coatings. The combination of high durability, mechanical resilience, and attractive finish ensures that the basecoat meets the demands of modern industry applications, particularly in automotive, construction, and heavy machinery sectors.
