Overview
OSP-09 L2000φ 16 formed steel wire coating bar is a Japanese OSP brand product, manufactured by extrusion process, made of 304 stainless steel, with chrome plating on the surface. This product is specially designed for precise control of Coat Weight, with a minimum control of 1.5μm wet film thickness, to achieve ultra-thin Spreader, effectively replacing traditional steel wire coating bar.
Features
1. Made by extrusion process to avoid the problem of loose wire and broken wire of traditional steel wire coating bar
2. Easy to clean, not easy to clog
3. The surface shape can be changed freely
4. Wide Groove Bottom, Greater Coating Weight
5. Accurate wet film thickness control, up to 1.5μm minimum
6. Specifications and lengths can be customized
Principle
Spreader liquid on the surface of the substrate, using a D-Bar formed wire coating bar to adjust (scrape off) the amount of liquid, through precise control of the wet film thickness to achieve uniform Spreader.
Applications
Film, Glass, Paper, Encasement Material, Tape, Magnetic Card
Steps
1. Spreader liquid on substrate surface
2. Use D-Bar formed wire coating bar to scrape off excess liquid
3. Adjust Coating Weight to desired wet film thickness
