KT - Advanced Pad Printing Ink
1. Overview & Applications
The KT Series is a premium industrial pad printing ink engineered with exceptional rheological properties to ensure flawless ink transfer and release from silicone pads. It is highly valued for its anti-stringing performance, superb opacity, and robust environmental resistance.
Applicable Substrates: ABS, PVC, PS, Polycarbonate (PC), Acrylic (PMMA), and Acrylic-painted surfaces.
Primary Applications: Electronic enclosures, home appliance casings, digital product components, office stationery, packaging, and powder-coated parts.
Note: While optimized for pad printing, the KT Series can also be effectively utilized for screen printing processes where exceptionally high color opacity is required.

4. Processing Guidelines & Additives
Mixing Formula & Viscosity
Thoroughly stir the thick paste ink before use. To achieve the correct pad printing transfer viscosity, add 20% - 30% of the appropriate thinner by weight.
- KT-100: Standard Thinner (Recommended for general workshop conditions).
- KT-200: Slow-Dry Thinner (Recommended for hot environments or fine detail printing to prevent pad drying).
Storage & Precautions
- Store in a cool, dry place tightly sealed. Keep away from heat and open flames.
- Shelf life is 2 years from the date of manufacture.
- Do not intermix KT Series inks with other brands or product lines to prevent adverse chemical reactions.
