Stamping Ink
This ink can be supplied in many colors and is primarily used for decorating balloons, toys and other rubber latex products by hand operation or automatic machinery. This ink is shipped in concentrated form or ready-to-use (designated as a “K” ink).
Concentrated Stamping Ink (100 Series)
As shipped, concentrated ink has to be diluted with a mineral spirit solvent in the proportion of 60% ink to 40% solvent by volume. Diluents can be shipped with the ink or may be purchased from a local supplier. We can also supply blended fast-dry solvents. After dilution, the ink should air dry in 3-5 minutes. If using a dryer, however, keep the temperature between 150ƒ-180ƒ. The dilution with the solvent should be done with intense mixing. The concentrates do not dilute easily and it is necessary to obtain an extremely homogeneous mixture. It is suggested to mix for at least 10-15 minutes with a high speed mixer. If using the whole container, you should pour the entire contents into a larger container and mix with a high speed mixer, after the diluent has been added. However, if using only a portion of the contents, be sure to mix the ink first in the original container with a high speed mixer, prior to pouring any out for use or dilution.
Ready-to-Use Stamping Ink (“K” Inks)
“K” Inks are diluted in our plant with a medium-fast drying solvent designated as Solvent No. 10. These inks should also be mixed thoroughly before use with a high speed mixer.
Intensifiers (900 Series)
Intensifiers may be used with the 100 Series Stamping Inks or 800 Series Silkscreen Inks when one is covering a dark surface with a light ink, or when a more opaque coverage is needed. NOTE: Intensifiers generally are not used alone. Due to the high pigment concentration they will not expand as well. Intensifiers should be added to the ink (which has been diluted with solvent and ready to use) in the range of 10% intensifier to 90% ink by volume and mixed thoroughly for 10-15 minutes with a high speed mixer.
Silkscreen Ink (800 Series)
This is a highly viscous ink available in a variety of colors for use in the usual silkscreening method of decorating any rubber latex object. A 200-325 mesh screen is recommended. Silkscreen inks are concentrated and should be diluted with a mineral spirit solvent in the range of 30% solvent to 70% ink by volume. Diluents can be supplied with the ink or purchased from a local supplier. We can also supply blended fast-drying solvents. After dilution, the ink should air dry in 3-5 minutes. If using a dryer, however, keep the temperature between 150ƒ-180ƒ. It is suggested to mix for at least 10 to 15 minutes with a high speed mixer. If using the whole container, you should pour the entire contents into a larger container and mix with a high speed mixer, after the diluent has been added. However, if using only a portion of the contents, be sure to mix the ink first in the original container with a high speed mixer, prior to pouring any out for use or dilution.
Marking Inks (200 Series)
This is a specially formulated ink supplied in many colors and used mainly for permanent marking of items like gloves and other rubber latex products that are not inflated. It provides wear-resistant, water insoluble coverage and is diluted in our plant with a fast drying solvent #29. Marking inks are shipped ready-to-use and only require thorough mixing before using. If further dilution is desired, blended solvents are available.
