BYK-354 is a polyacrylate-based surface additive for solvent-borne and solvent-free coatings, UV-curing printing inks, overprint varnishes, and ambient curing plastic systems. It functions as a standard leveling agent with a deaerating effect, improving deaeration and offering thermal stability. Suitable for radiation-cure applications, it is in liquid form and is ideal for solventborne and solventless high solids coatings.

Product Applications

Coatings and Printing Inks
Special Features and Benefits

The additive is used as an anti-cratering and leveling additive, increases gloss and gives a long wave effect. It only provides a minor reduction of the surface tension and does not negatively influence the recoating/overprinting capabilities and intercoat adhesion. As a result of its high molecular weight and its non-polar structure it also has a deaerating effect. The additive is thermally stable.
Recommended Use : The additive is recommended for solvent-borne and solvent-free coating systems, UV-curing printing inks and overprint varnishes.
Recommended Levels
0.1-1.5% additive (as supplied) based upon total formulation. The above recommended levels can be used for orientation. Optimal levels are determined through a series of tests.
Incorporation and Processing Instructions : The additive can be incorporated during any stage of the production process, including post-addition. Better deaeration can be achieved by adding to the mill base.
Ambient-curing Plastic Systems
Special Features and Benefits

The additive is used as an anti-cratering and leveling additive, increases gloss and also has a deaerating effect as a result of its high molecular weight and non-polar structure. It only reduces surface tension slightly. The additive is thermally stable.
Recommended Use: The additive is recommended for all ambient curing resin systems such as unsaturated polyester resins and epoxy resins.
Recommended Levels
0.1-1.5% additive (as supplied) based upon total formulation. The above recommended levels can be used for orientation. Optimal levels are determined through a series of laboratory tests.
Incorporation and Processing Instructions : The additive can be incorporated during any stage of the production process, including post-addition. Better deaeration can be achieved by adding to the mill base.

Coatings Industry
Special Features and Benefits

The additive is used as an anti-cratering and leveling additive in all solvent-borne coatings. It increases gloss and produces a long wave effect. It reduces the surface tension only to a slight extent, and does not impair the recoatability and intercoat adhesion. The additive is thermally stable.
Recommended Levels
0.1-1.0% additive (as supplied) based upon total formulation. The above recommended levels can be used for orientation. Optimal levels are determined through a series of laboratory tests.
Incorporation and Processing Instructions : The additive can be incorporated during any stage of the production process, including post-addition.
