Product Application

Printing Inks and Overprint Varnishes

Special Features and Benefits

  • Due to its high surface activity, BYK-UV 3500 accumulates on the surface of the coating.
  • Its acrylic functionality enables it to be incorporated in the polymer network and therefore to be anchored permanently to the coating surface.
  • The additive provides high surface slip and improves leveling and substrate wetting.

Recommended Use
BYK-UV 3500 is particularly recommended for all non-aqueous, radiation-curable flexographic, offset and screen printing inks, also for radiation-curable overprint varnishes.

Incorporation and Processing Instructions
The additive can be incorporated during any stage of the production process, including post-addition.

Adhesives

Special Features and Benefits

  • Due to the considerable reduction in the surface tension, BYK-UV 3500 improves the substrate wetting and the leveling of adhesives.
  • Due to its high surface activity, the additive accumulates on the surface.
  • Its acrylic functionality enables it to be incorporated in the polymer network and therefore to be permanently anchored to the surface.
  • Its good compatibility enables highly transparent adhesives to be formulated without turbidity.

Recommended Use
Recommended for non-aqueous, radiation-curable adhesive systems.

Incorporation and Processing Instructions
The additive can be incorporated during any stage of the production process, including post-addition.

Coatings Industry

Special Features and Benefits

  • Due to its high surface activity, BYK-UV 3500 accumulates on the surface of the coating.
  • Its acrylic functionality enables it to be incorporated in the polymer network and therefore to be anchored permanently to the coating surface.
  • As a result of crosslinking via its acrylic functionality, in aqueous UV systems, BYK-UV 3500 provides very good leveling, high surface slip and tape release with permanent effect.
  • As a result of crosslinking via its acrylic functionality and the improvement in leveling, in non-aqueous, radiation-curable systems, BYK-UV 3500 provides outstanding surface slip and tape release with permanent effect.

Recommended Use

  • The additive is particularly suited to aqueous and non-aqueous, radiation-curable coatings, whereby it can crosslink with the binder in these systems.
  • It is also possible to use it in conventional curing systems, however without crosslinking with the binder.

Incorporation and Processing Instructions
The additive can be incorporated during any stage of the production process, including post-addition.
