Dyna Ace-2 layer edged. The ultra-tough technology researched by Osaka Chemical of Japan uniquely, which the hardness can reach 130 JISA and has ultra-resistant to the solvents, ultra-low expansion rate, ultra wear-resistance and ultra long life, is on a par with stainless steel exclusive squeegees. It applies to the irregular printing, cylinder printing and fine or small printing, which is better than the flat squeegees can’t print on the extreme fine-millimeter grade line width processes. The lower soft squeegees can scrape redundant solvent raw materials and reduce expenditure of raw materials for factory.
