UV401
UV401 is a silicone surface additive. It is used in solvent-free, radiation-curing, solvent-based coating systems, adhesives, and printing inks to significantly reduce surface tension. At the same time, its high compatibility allows it to be used in the production of high-transparency varnishes without causing cloudiness.
Product Description
Product Features
Low surface tension, increased slip, and substrate wetting.
Compatible with acrylic resins, alkyd resins, amides, epoxy resins, nitrocellulose, phenolic resins, polyester resins, and vinyl systems.
Recommended Applications
Mainly used in solvent-based and solvent-free two-component polyurethane systems, UV-curable coatings, polyester/melamine baking coating systems, and a range of water-based systems.
Wood and furniture coatings, can coatings
Coil coatings and leather finishing agents
Application Areas
Topcoat varnishes (can improve tape release in topcoat varnishes.)
Flexographic inks
Offset inks
Screen printing inks
Printing inks for high-speed presses
Recommended Dosage
0.05-2% additive dosage (as supplied) based on total formulation.
*The above recommended additions are for reference; the optimal addition level should be determined through a series of tests.
Processing Instructions
The leveling agent can be pre-diluted or added directly to the coating as supplied.
This additive can be added at any stage of the production process, including post-addition.
Low temperatures can cause cloudiness or solidification, but this can be eliminated by raising the temperature, and product performance is not affected.
