Until now it has only been possible to either reduce the surface energy of cured coatings by adding silicone additives or to maintain its original level by adding acrylate leveling additives. Using the new BYK®-3560 from BYK Additives & Instruments the surface energy of cured coatings can now even be increased.
BYK®-3560 is based on macromer technology which, as a result of the combination of product properties, opens up new avenues in terms of surface modification. BYK®-3560 increases the surface energy of cured coatings overall, especially the polarity resulting in an improvement in the adhesion of subsequent layers such as paints, lamination foils, adhesives, printing inks etc.
This additive also provides better wetting of the cured coating by the subsequent layer and a very good leveling of subsequent layers. Additionally, it improves the leveling of the system in which it is being used. BYK®-3560 does not influence the surface tension of the liquid coating and retains the high transparency of clear coats.
BYK®-3560 is silicone- and fluorine-free and has 100 % active substance. Its usage is recommended to a wide range of systems: aqueous, solvent-borne, UV-curable, and high solid.
About BYK Additives & Instruments:
BYK Additives & Instruments is a leading supplier in the field of additives and measuring instruments.
Additives are chemical substances which, when used in small quantities, improve product properties such as scratch resistance or surface gloss. They permit the rheological behavior of liquid materials to be adjusted, providing the optimum conditions for smooth-running manufacturing and application processes.
The coatings, inks and plastics industries are among the main consumers of BYK additives. Yet with exploration technology of oil/gas, the manufacture of care products, the manufacture of adhesives and sealants, and construction chemistry, too, BYK additives improve the product characteristics and production processes.
Testing and measuring instruments from BYK effectively evaluate the quality of color, gloss and appearance as well as the physical properties of paint, plastic and paper products and are an important part of quality control.
As a globally operating specialty chemicals company, BYK has production sites in Wesel, Kempen, Moosburg and Schkopau (Germany), Deventer and Denekamp (Netherlands), Widnes (UK), Wallingford, Gonzales, Louisville (USA) and Tongling (China).
BYK‘s instrument section (BYK-Gardner) is based in the Upper Bavarian town of Geretsried.
Today the company employs more than 1,800 people worldwide and forms part of the ALTANA Group.
