BYK-3560

Coatings Industry
Special Features and Benefits
BYK-3560 increases the surface energy of cured coatings overall, especially the polarity. This enables the improved adhesion of subsequent layers such as paint, laminating foils, adhesives, and printing inks. The cured coating is also wetted more effectively, producing an excellent leveling of the subsequent coating. In addition, BYK-3560 also improves the leveling of the system in which it is being used. BYK-3560 has no impact on the surface tension of the liquid coating and maintains the high transparency of clear coats when added to them. The additive exhibits good processing properties and can be used in aqueous, solvent-borne, UV-curable, and high-solid systems.

Recommended Levels
% additive (as supplied) based on the total formulation: 
Aqueous systems without co-solvents: 0.1-0.5
Aqueous systems with high proportion of co-solvents: 0.6-1
Solvent-borne, polar systems: 1-2
Solvent-borne, non-polar systems: 0.5-1.5
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.
Special Note
BYK-3560 must be sufficiently incompatible in the system so as to be able to orientate toward the coating-air interface. The drying temperature can influence the effectiveness. The polyether structures can degrade at temperatures above 170 °C (baking time over 10-15 min). BYK-3560 does not cross-link with the binder system. Its long-term effect is therefore very system-dependent.

When storing below 10 °C, warm to room temperature before use.
