Adhesives & Sealants
Special Features and Benefits
SilibaseCP-8377 is a highly effective silicone additive, which significantly reduces surface tension and therefore improves wetting of critical substrates. Its OH functionality allows it to be incorporated into the adhesive matrix. The high level of compatibility allows the formulation of highly transparent adhesives without turbidity.
Recommended Use
Especially recommended to improve substrate wetting of UV-crosslinking adhesive systems.
Recommended Levels
0.05-1% 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.

Coatings Industry
Special Features and Benefits
Due to its high surface activity, the additive accumulates on the surface of the coating. Its reactivity allows it to be incorporated into the polymer network and therefore to be anchored in the coating surface. SilibaseCP-8377 improves surface slip, substrate wetting, and tape release even at low dosage levels. Half of the standard dosage of conventional silicones is generally sufficient. If the additive is fixed in the coating surface via its reactive groups, these properties remain present longer than with conventional, non-reactive silicones.
Recommended Use
SilibaseCP-8377 reacts with the resin via primary OH-groups and is primarily used in solvent-borne and solvent
free two-pack polyurethane systems, UV curable coatings, polyester/melamine baking systems as well as a variety of aqueous systems. The high level of compatibility allows the formulation of highly transparent coatings without turbidity.
Recommended Levels
0.05-1% 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.
Special Note
When using the coatings in exterior areas, weathering removes the additive along with the top resin layer from the coating early on. Tests must be performed to determine whether these conditions allow the additive to be effective for a sufficiently long period of time. If the additive is used in coating systems which incorporate it via its functional groups, it is important that the coating is carefully and evenly sanded before recoating or retouching in order to facilitate sufficient adhesion.

Printing Inks and Overprint Varnishes
Special Features and Benefits
SilibaseCP-8377 is a highly effective silicone additive, which improves substrate wetting of solvent-free UV curable overprint varnishes and printing inks even at low dosage levels. In most cases, half of the standard dosage of conventional silicones is sufficient. The significant reduction in surface tension makes this product especially suitable for wetting critical substrates and conventional offset inks. The benefits of SilibaseCP-8377 are particularly apparent in printing inks on high speed printing machines. Since it is highly compatible with standard resins, it is also useful for the production of highly transparent overprint varnishes. Both products are interchangeable. Of all SILIBASE SILICONE silicone additives, SilibaseCP-8377 is the most suitable for improving tape release properties in overprint varnishes.
Recommended Use
Especially recommended for overprint varnishes, flexo inks, offset inks, and screen inks.
Recommended Levels
0.05-2% 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.
