2500 Series Inks

The 2500 series is a family of inks for printing on acrylic resins, and features outstanding weather resistance and clarity for screen printing on nameplates and electrical signs. The inks in this series are air-drying inks of low odor. They are free of peeling. discoloration, fading, or cracking at the time of forming. Use of exclusive solvents is highly recommended as acrylic resins are affected relatively easily by solvents. Moreover, the inks in this series must never be mixed with other inks,

Specifications
Ink type Air-drying ink of low odor level consisting of acrylic resin, other special resins, and high-quality coloring pigments of high weather resistance.
Usage Ideal for printing on nameplates and electrical signs made of acrylic resin and other plates.
Finish Semi-gloss (slightly varying with the color) finish with good leveling and smooth film of outstanding pattern reproduction. Outstanding transparency and coloring for electrical signs.
Coverage and shading power Outstanding covering power of black color for nameplates.
Clarity r Clarity Eight transparent colors are available. 110 (electrical sign white) emphasizing semitransparent white is also available for lining under electrical signs.
Weather resistance Weather resistance is reduced when printed on the exterior. Also, chalking may occur with high concentration colors. Sample before use.
Secondary processability Outstanding secondary processability (heat resistance, etc.) after printing, especially for post printing forming of electrical signs without cracking or discoloration
Adhesion Outstanding adhesion especially to acrylic resin plates, plus weather resistance for use with electrical signs
Drying time Air-dries (20°C) in about 30 minutes (sets to touch). Curing for 5-10 minutes after printing at temperature 60-80°C will further increase adhesion, Troubles due to drying conditions and other factors may result when printing on molded signboards, especially when they are let to dry on racks in poorly ventilated and cold places. These problems can be prevented by the addition of quick-dry solvent and by thermal curing Acrylics resin plates should be stored carefully as they easily absorb moisture and cracks will result when printing on moist resins.
Viscosity adjustment Ideal viscosity varies with the printing environment. Normally, an adequate working viscosity is obtained when T-2500 is added to the ink in proportion of 5-15 to 100 (ink).
Slow-dry Solvent Use T-2500S or T-980 for summer or precision printing.
Screen Use of water-soluble cut film or photomechanical process in combination with Tetron or nylon screens of 200-300 mesh is recommended
Wash-up Use T-15 for economical wash-up
Notes The inks in this series must never be mixed with other inks. Use of exclusive solvents is highly recommended as ordinary solvents will affect drying time and cause crazing and other problems in the material and the printed film.
