DISPERBYK-2205 - Solid wetting and dispersing additive for a multitude of solvent-borne applications and UV printing inks
DISPERBYK-2205 is an extension to BYK’s product family of solid and very effective wetting and dispersing additives. As a result of the optimal molecular weight distribution the additive is highly compatible in a variety of systems; the reduced amine value leads to an almost neutral character and enables it to be used in acid catalyzed systems. DISPERBYK-2205 offers a low handling viscosity and a perfect pigment stabilization combined with a high gloss and low haze in industrial, coil, automotive, wood and furniture coatings. In printing ink applications it can also be used for medium-polarity systems and even UV systems.

BYK-326 - High-solid, moderately active surface additive for improving the leveling of solvent-borne, solvent-free and aqueous systems
If the broadest possible compatibility is required, for instance to also be compatible with aqueous systems, it would be preferable to use a medium-polarity additive. The new BYK-326 provides a balanced profile and ideally completes the BYK range with regard to universal application in all systems. It has medium polarity and displays moderate activity in reducing surface tension, which produces excellent leveling results.

CERAFLOUR 927 – Micronized, modified wax additive for improved mechanical properties in aqueous systems
Wax additives are added to coatings to provide them with a matt appearance and to improve their mechanical properties (primarily scratch and abrasion resistance) and their resistance to water or chemicals. As a result of their chemical composition, the majority of powdered wax additives require an increased dispersion effort to achieve optimum effectiveness when incorporated into aqueous systems, particularly if no organic co-solvents are added. CERAFLOUR 927 has been developed specifically for use in aqueous systems and is characterized by being easy to incorporate. The wax distributes well in the coating system even without the addition of co-solvents and remains well distributed which results in excellent storage stability. CERAFLOUR 927 is formaldehyde-free and can be post-added.

BYK-W 908 - Wetting and dispersing additive to reduce the viscosity in highly filled UP casting resin systems
Only available in Europe.
BYK-W 908 is a wetting and dispersing additive with properties that greatly reduce viscosity. It is therefore particularly recommended for highly filled UP casting resin systems. BYK-W 908 improves the flow behavior and the leveling of the resin mixture of casting resin systems such as polymer concrete, artificial marble, or onyx, without impacting the curing or color. In contrast to BYK-W 909, BYK-W 908 is listed under REACH and therefore the direct alternative.
02.05.2016 - BYKO2BLOCK-1200
BYKO2BLOCK-1200 - Barrier additive for PLA-based food packaging applications
BYKO2BLOCK-1200 is a barrier additive based on modified pyllosilicate to provide a significant improvement of impermeability (>30%) towards gases such as oxygen, carbon dioxide and water vapor in PLA systems. This effect is achieved by an equal distribution of the BYKO2BLOCK-1200 platelets in the polymer matrix during processing (compounding). The optimum performance is realized without changing other properties such as the mechanics or transparency. Moreover, BYKO2BLOCK-1200 also improves thermal endurance.
25.04.2016 - AQUACER 530
AQUACER 530 is a HDPE wax emulsion for printing inks, overprint varnishes, inkjet inks and wood coatings The additive improves rub respectively scratch resistance and provides a higher surface slip.
AQUACER 530 is mainly recommended for over print varnishes on absorbing substrates. In inkjet inks AQUACER 530 has no influence on viscosity, gloss and filterability.
15.02.2016 - BYK-C 8003
BYK-C 8003 - Reactive polymeric coupling agent for improving the mechanical properties of glass fiber reinforced, radical curing systems based on unsaturated vinylester and polyester resins
BYK-C 8003 has been developed specifically for use in radical curing, glass fiber reinforced unsaturated vinylester and polyester resin systems. The additive improves the mechanical properties of the component through increased fiber-matrix bonding. The level of the improvement depends on the choice of the glass fiber and resin system.
BYK-C 8003 guarantees a constantly high quality of the finished part with no influence on water absorption, glass transition temperature, etc..
The additive is liquid and therefore easy to incorporate.
01.02.2016 - BYK-SILCLEAN 3701
BYK-SILCLEAN 3701 - Silicone-containing Surface Additive for Epoxy Systems for Long-term Improved Cleanability (Easy-to-Clean Effect)
The use of epoxy resin systems as top coats using cycloaliphatic hardeners has increased in recent years. BYK has developed a silicone-containing surface additive for storage room, tanks, tunnel or container coatings specifically to improve cleanability.
BYK-SILCLEAN 3701 achieves a permanent effect as it reacts in the polymer matrix. The additive has no influence on the adhesion of the top coat to the substrate and consequently does not have a negative effect on the anti-corrosion properties. A further advantage is also the improvement of leveling and surface slip, as well as the lack of foam stabilization.
BYK-SILCLEAN 3701 is equally suitable for conventional, high-solid, and solvent-free epoxy resin systems.
04.01.2016 - BYK-1611, BYK-1617, BYK-1723 and BYK-1724
As a reaction to the tighter European legal requirements, BYK has developed a series of highly effective defoamers that comply with the recent standards and can be used without any restrictions. This meets the users´ requirements for easy adaption of their current formulations to the latest safety and environmental directives. The new defoamers are easy to incorporate and recommended for a multitude of aqueous systems.
