Aktifit VM offers highest color neutrality, best disperson properties, lower viscosity at low shear rates, improved abrasion resistance and improved hiding power without UV-curing problems in white pigmented top coats.
- low sedimentation
- no hard sediment
- low abrasivity
- scratch resistance
- abrasion resistance
- very good transparency
- adjustable matting effect through choise of product
- no effect on UV-curing
