Stenshel® (stainless steel flake-containing paint)
Overview
Stenshel® paint (stainless steel flake-containing paint) is a rust-resistant paint that is excellent against corrosion.
By applying a resin film containing fine stainless steel flakes having strong rust-preventing capabilities against corrosive components, such as acids, alkalis, and salts, it blocks scratching and corrosive factors, prevents the generation of rust, and protects materials over the long term.
*Stenshel® is a new technology paint that has acquired a New Technology Information System (NETIS) Registration Number from the Ministry of Land, Infrastructure, Transport and Tourism.
A laminated coating film containing stainless steel flakes that are strongly compatible with and adhered to a resin exhibits weather resistance, corrosion resistance, and chemical resistance superior to that of conventional thick anti-corrosion paints.
-
- 1) While the paint resin is hardening, the fine stainless steel flakes overlap in a layer on a planar surface.
- 2) A laminated film of continuous stainless steel flakes forms inside the resin. Furthermore, when the resin hardens, a strong, tough coating that is resistant to external force and corrosive substances, such as water, is created.
-
Abalone shells, which are said to be strong and tough to break, include iridescent layers called mother of pearl, and thus have multi-layered structures formed by many overlapped plates of thin pearl aragonite crystal. In the same way, Stainless Shell paint forms a strong, tough coating film because a multi-layered structure of stainless steel flakes forms in the resin.
Features
Strong points
- 1. Corrosion protection and weather resistance are superior.
- 2. Chemical resistance is superior.
- 3. Friction resistance is superior so that it can be used on parts where strong forces are generated.
<Other strengths>
- ●Can be applied by spraying, brushing, or rolling, etc.
- ●Can be selected according to applying location etc. because the basic color lineup is comprised of 12 colors.
- ●Able to reduce painting processes with the goal of saving construction labor.
- ●It is highly durable and thus extends periods between re-painting.
Applications
3 painting specifications
Effective for locations where long-term anti-corrosion and weather resistance are required, such as bridges, railway girders, factories, hydraulic steel piping, steel framing, cubicles, concrete forms, and bolts.
