|SPARKLEBRITE™ PREMIER 2052NL-PA Aluminum Paste|
Premier 2052nl-PA is a coarse particle size, brilliant, non-leafing
aluminum pigment based on lenticular flake geometry. This pigment is
typically used to produce strong, clean metallic effects in liquid
flexographic and gravure ink systems. This grade can be used in
combination with transparent dyes or pigments to produce a spectrum of
bright, clean metallic colors. SparkleBrite™ Premier is produced as a
pigment paste carried in isopropyl alcohol but is not treated to
inhibit the aluminum-water gassing reaction. Because it is not
chemically passivated, it should not be used in aqueous inks without
careful evaluation of stability.

|SparkleBrite™ Premier pigments are non-leafing aluminum pigment pastes carried in isopropyl alcohol. These grades are based on lenticular flake geometry and offer enhanced metallic effects in solvent and waterborne flexographic and gravure inks. The lenticular flake geometry produces strong, highly brilliant and very clean metallic effects. Although SparkleBrite™ Premier pigments can be used in aqueous inks, they are not treated to protect against the aluminum-water reaction and special care must be taken to evaluate the gassing stability of each grade in the final ink formulation. High or excessive shear during ink production can initiate the aluminum-water reaction. Care must be taken to avoid excessive or high shear during processing when used in ink formulations containing water.|
|The paste should be pre-soaked in solvent at a paste:solvent ratio of between 1:1 to 3:1. Polar solvents should be avoided with leafing grades due to their adverse effect on leafing stability. When formulating aqueous inks, the pH of the system should be kept as close to neutral as possible. Pre-soaking generally takes from one to eight hours. Finer grades typically take longer than coarser grades. Use low shear, slow speed mixing to achieve a smooth consistency free of agglomerates. High shear dispersion techniques should be avoided, as they will distort the aluminum flakes.|
|SAFETY AND HANDLING|
Aluminium pigment should be stored in the original shipping container and kept tightly sealed. Store containers in a dry room at a temperature below the flash point of the solvent. Avoid any conditions that will suspend or float the particles in the air, creating a dust cloud.
