Special properties
Scope of application
The additive is suitable for all solvent-borne, solvent-free and aqueous coatings, printing inks and overprint varnishes.
It is particularly recommended for improving the substrate wetting of adhesive systems based on
polyurethanes, epoxies and acrylates.
It can also be used for improving the substrate wetting of ambient-curing polyurethane and epoxy based systems.
Incorporation and Processing Instructions
The additive can be incorporated during any stage of the production process, including post-addition.
Recommended Levels
0.05-0.3% additive (as supplied) based upon total formulation. In aqueous and UV systems up to 1%.
The above recommended levels can be used for orientation. Optimal levels are determined through a series of laboratory tests.
Package and storage
The standard package is 25kg plastic/iron drums, 18 drums per pallet.
Keep containers tightly closed in a dry, cool, and well-ventilated place. Separation or turbidity may occur at temperatures below 5°C. Warm to 20 °C and mix well. When stored in an original unopened packaging, the product has a shelf life of 12 months from the date of manufacture.
