It is a colorless and transparent high corrosion-resistant topcoat specifically for zinc substrates.
The ultra-corrosion-resistant thin film coating "ZEC-COAT" is a colorless and transparent high-corrosion-resistant topcoat specifically designed for zinc substrates. Yahata Screw has established an immediate delivery system with a stock of approximately 100,000 types of fastening parts used in various fields such as automotive, machinery, electronics, medical, and construction. Additionally, we collaborate with our own manufacturing and partner manufacturers to provide the best "product selection," "high quality," "low price," and "reliable delivery times" that our customers demand, including special products for cold forging and machining. 【Features】 ○ By coating zinc-plated surfaces, we can achieve a non-chromium high corrosion-resistant film at a low cost. ○ Coating with trivalent chromate (white and black) significantly enhances rust prevention performance (approximately 5 times the corrosion resistance). → In salt spray tests, white rust occurs after more than 360 hours, and red rust occurs after more than 1500 hours. ○ It has self-healing properties against scratches.

basic information
【Features】 ○ The torque coefficient is stable (overall friction coefficient approximately 0.3) ○ The silica-based treatment solution does not contain rare metals, ensuring stable pricing ○ Ideal for cost reduction strategies for zinc alloy plating → Half the cost of zinc-nickel plating and one-third the cost of zinc-iron plating (compared to our company) ○ Smooth screw fitting with a thin film (less than 1μm) → Can also serve as an alternative to zinc-aluminum composite baked coatings, which have weaknesses in appearance and fitting ○ If used as a topcoat for zinc-aluminum composite baked coatings, it provides an unparalleled ultra-high corrosion-resistant coating ● For more details, please contact us or download the catalog.
