Introduction to a long-term corrosion protection system for steel materials using room temperature metal thermal spraying.
The Puzzle Method is a super long-lasting corrosion protection technique that dramatically enhances the corrosion resistance of sacrificial anti-corrosion metal spraying (aluminum/zinc) combined with anti-corrosion coatings. Invented in Europe about a century ago and developed in Japan as a construction technology, it integrates the metal spraying technology with over 120 years of expertise from Nippon Paint's coating technology, established with the desire to "protect steel materials, the backbone of civil engineering and construction, across centuries." 【Goals of the Puzzle Method】 ■ Improvement of expected service life for corrosion resistance ■ Reduction of LCC (Life Cycle Cost) ■ Enhancement and generalization of maintenance technology ■ Gaining trust in steel materials *For more details, please refer to the PDF document or feel free to contact us.
