New Additives

19.05.2020 - BYK-C 8014

BYK-C 8014 – Solvent-free, polymeric coupling agent to increase the mechanical strength of carbon fiber-reinforced radical-curing systems 

The additive is used in vinyl ester resins that will be subsequently processed with carbon fibers into composite components. The transverse tensile strength of the fibers is considerably increased and therefore enables greater design freedom.  The improved fiber-matrix adhesion increases the flexural properties of the composite. BYK-C 8014 is mainly suitable for isocyanate thickened vinyl ester formulations, easy-to-use and shows a good stability in the resin.

05.05.2020 - BYK-3480 and BYK-3481

BYK-3480 and BYK-3481 – Combined surface additives for aqueous systems 

BYK-3480 and BYK-3481 are 100 % silicone surfactants to improve substrate wetting by means of a strongly reduced surface tension in the liquid coating. They provide excellent defoaming and anti-cratering properties combined with good leveling.
BYK-3480 is slightly more polar than BYK-3481 and particularly suitable for pigmented systems whereas BYK-3481 is slightly less polar and particularly suitable for clearcoats.

10.03.2020 - AQUACER 1550 R, CERAFLOUR 981 R, CERAFLOUR 996 R, CERAFLOUR 997 R, CERAFLOUR 998 R, and CERACOL 607 R

AQUACER 1550 R, CERAFLOUR 981 R, CERAFLOUR 996 R, CERAFLOUR 997 R, CERAFLOUR 998 R, and  CERACOL 607 R – EU REACH-compliant PTFE wax additives from BYK

Ammonium and sodium salts in perfluorooctanoic acid (PFOA) occur in the course of manufacturing and processing various fluoropolymers such as polytetrafluoroethylene (PTFE). With effect from July 4, 2020, the EU is severely restricting the handling of PFOA and related compounds. With effect from June 30, 2020, BYK will therefore be discontinuing the production and sale of wax additives containing a PTFE with a PFOA content of above 25 ppb. The additives concerned will be replaced by new, low-PFOA (< 25 ppb) and hence EU REACH-compliant versions.

These variants can replace the originals on a one-to-one basis.

03.03.2020 - BYK-1709, BYK-3751, BYK-3753, BYK-3763, and BYK-3780

BYK-1709, BYK-3751, BYK-3753, BYK-3763, and  BYK-3780 – Silicone additives with a significantly reduced content of cyclic siloxanes

The European Chemicals Agency (ECHA) added the cyclic siloxanes D4, D5 and D6 to the EU REACH candidates list for “Substances of Very High Concern” (SVHC). BYK is obliged to show this information on the EU safety data sheet (section 15) if at least one of these substances is present in a BYK additive in a quantity of 0.1 % or greater. It means that when the affected additives are used in coatings, plastics, printing inks or adhesives, and in the various end applications, increased demands on the protection of health and safety can be required. To keep the use of the silicone additives in question as simple and uncomplicated as possible, BYK has purified well-known standard additives and is now offering versions of these products with a low cyclic siloxanes content. They are SVHC label-free and can be dosed and applied in the same way as the standard versions, hence there is no need to change the formulation.

Please see as well the products BYK-1707, BYK-3750, BYK-3752, BYK-3754, BYK-3761, BYK-3762, BYK-3764, BYK-3770, and BYK-3771 that were launched in August 2019.

21.01.2020 - CLAYTONE-MPZ

CLAYTONE-MPZ – High-performance organoclay for medium to high-polar systems

Organophilic phyllosilicates are characterized by a versatile range of properties.  They are e.g. used in all types of primers, intermediate coatings, and topcoats, sometimes in combination with other rheological additives. In addition to anti-settling properties, they also offer anti-sagging properties. CLAYTONE-MPZ is especially suitable for applications with high requirements with regard to rheology. It has been specially processed to ensure maximum performance, which gives this organoclay an edge over the rest of the product portfolio.

07.01.2020 - BYK-1751

BYK-1751 – Polymer-based, silicone- and aromatic-free defoamer for solvent-borne printing inks and coating systems with a broad compatibility

BYK-1751 prevents foam formation in printing ink and coating systems during production and filling. It prevents air entrapment during processing. The additive spontaneously destroys foam and does not reduce intercoat adhesion during recoating. It does not contain aromatic solvents and silicones.
BYK-1751 is the aromatic-free version of BYK-051 N.
