BYK-UV 3570

BYK UV 3570 is a polyester-modified, multi-acrylic functional polydimethylsiloxane surface additive solution that reduces surface tension and increases surface slip. BYK UV 3570 orientates itself at the surface due to its high surface activity. Its acrylic functionality enables it to be incorporated in the polymer network and anchored there. Depending on the dosage, BYK UV 3570 provides a controlled increase in the surface slip, enabling the required slip to be adjusted more easily. It also improves leveling, substrate wetting and orientation of matting agents. If fixed to the surface via its reactive groups, these properties are maintained for a long period of time. BYK UV 3570 is particularly suitable for solvent-free, radiation-curable coatings used in construction and manufacturing where a reduction in surface tension and increase in surface slip provides benefits such as improved application properties and durability of finished materials.
