Chemi Tech Anti-Scratch Additive for UV Ink Printing

The high viscosity of UV inks often causes blade streaks and misting during transfer from anilox rolls, leading to speckle defects on printed surfaces. At speeds exceeding 150 meters/minute, friction between doctor blades and anilox rolls intensifies, significantly increasing scratch risks.

Chemi Tech's KMR-3001 Anti-Scratch Address addresses these issues through rheological modification:

Dynamic Viscosity Control: Reduces ink thixotropy to improve shear flow in blade contact zones;

Surface Energy Optimization: Fluorinated compounds minimize ink residue in anilox cells, preventing blade buildup;

Micro-Defect Repair: Fills micro-cracks in ink layers during curing for enhanced smoothness.

Case Study: Label Printer Efficiency Breakthrough

A flexo label manufacturer encountered 4-5 annular scratches per shift on PET labels, requiring and generating 50+ meters of waste. After using KMR-3001:

Added at 1.5% of ink weight, scratch frequency decreased 80%;

UV ink mist spots reduced by 70%, lowering rework costs;

Anilox roll polishing intervals extended from 2 to 8 weeks.

KMR-3001 is compatible with rotary and label presses, maintaining print gloss while drastically reducing waste. Chemi Tech upgrades printing stability through advanced surface treatment.
