Stainless steel flake pigments are the result milling stainless steel to form a uniform particle size. Adding these powdered particles to a coating systems to resist corrosion and ultraviolet attack.
Stainless Steel flake pigments have been used commercially in protective coating formulations for metal substrates since the early ‘50’s. Their use is now well established in industrial maintenance and specialty coatings and continues to increase. STAY/STEEL pigments incorporated in a variety of high solids solvent based and water based systems improve the performance of conventional protective coatings.
STAY/STEEL, a stainless steel flake pigment, products are pigments produced on ball mills. The products consist of AISI 316L alloy, which are milled to a uniform particle size. STAY/STEEL stainless steel pigments act in two ways, chemically and mechanically.
Chemically, STAY/STEEL pigments resist corrosion and ultraviolet attack. Mechanically, they are strong, hard and highly abrasion resistant. STAY/STEEL stainless steel pigments are non-leafing which permits the flakes to build up a multi-layer structure tightly bonded to the substrate.
Resistance to UV Degradation:
High Temperature Resistance:
Recently, newly developed ultra “LOW NICKEL” STAY/STEEL flake pigments have been introduced to the market due to demands from a regulatory standpoint, with the nickel being less than 0.1%. These low nickel pigments complete the STAY/STEEL product portfolio and offer similar functional properties to the standard STAY/STEEL pigments but have a slightly different optical effect, having a “bluer” shade compared to the standard.
STAY/STEEL pigments offer a high level of functional properties and are recommended for the following applications:
STAY/STEEL pigments are supplied in “dry form/ pigment”, allowing the formulator the flexibility to formulate coatings in their own solvent/ binder technology. Standard packaging size is 25Kg (EU) and 55Lbs (USA).
The processing of STAY/STEEL is similar to other aluminum pigment dispersions for solvent based and water based coatings. They are typically added to the finished paint or ink while stirring constantly. However, compared to conventional aluminum pigments, STAY/STEEL pigments show significant improvement in shear stability.
For STAY/STEEL pigments, the total shelf life is 24 months.
