BYK-UV3505 is a polyacrylate-functional polysiloxane Wetting Dispersans Agents designed for radiation-curable coatings and inks. It enhances substrate wetting through significant surface tension reduction, particularly on hard-to-wet surfaces. As a crosslinkable additive, it provides durable anti-scratch and easy-clean properties while maintaining compatibility with solvent-free, solvent-based, and aqueous systems
Reactive Technology - Acrylate groups enable permanent fixation via crosslinking with UV-curable systems
Surface Optimization - Provides excellent substrate wetting (even on plastics/coated papers) and anti-cratering
Dual Functionality - Combines flow promotion with lasting slip and tape-release properties
Process Flexibility - Addable at any production stage, including post-blending
Optical Clarity - Maintains transparency without haze in clear coats
Printing Inks - Flexographic/gravure inks for packaging films requiring low COF (0.2-1% dosage)
Wood Coatings - UV-cured matte topcoats with consistent gloss control
Industrial Coatings - Abrasion-resistant finishes for metal/plastic components
Overprint Varnishes - High-gloss UV coatings with anti-fingerprint effects
Adhesives - Radiation-curable formulations needing improved wetting (0.1-0.5% dosage)
