BYK-UV3500 Wetting Dispersans Agent

BYK-UV3500 is a polyether-modified polysiloxane with acrylate functionality Wetting Dispersans Agents, designed for radiation-curable coatings, inks, and adhesives. It significantly reduces surface tension to enhance substrate wetting and flow properties while preventing cratering. Its reactive groups enable covalent bonding with UV matrices, ensuring non-migrating performance and durable surface effects

Effect of BYK-UV3505 Wetting Dispersans Agents

  1. Reactive Technology - Acrylate groups enable permanent fixation via crosslinking with UV-curable systems

  2. Surface Optimization - Provides excellent substrate wetting (even on plastics/coated papers) and anti-cratering

  3. Dual Functionality - Combines flow promotion with lasting slip and tape-release properties

  4. Process Flexibility - Addable at any production stage, including post-blending

  5. Optical Clarity - Maintains transparency without haze in clear coats

Typical Applications of BYK-UV3505 Wetting Dispersans Agents

  1. Printing Inks - Flexographic/gravure inks for packaging films requiring low COF (0.2-1% dosage)

  2. Wood Coatings - UV-cured matte topcoats with consistent gloss control

  3. Industrial Coatings - Abrasion-resistant finishes for metal/plastic components

  4. Overprint Varnishes - High-gloss UV coatings with anti-fingerprint effects

  5. Adhesives - Radiation-curable formulations needing improved wetting (0.1-0.5% dosage)
