16.07.2019 - RHEOBYK-7405
RHEOBYK-7405 – Aromatic- and tin-free thixbooster for solvent-free and solvent-borne systems. Aromatic-free variant of RHEOBYK-405.
Organophilic phyllosilicates and fumed silica are used in coatings in order to control rheological properties such as settling, syneresis and sag resistance. Additionally thixboosters like the new RHEOBYK-7405 can be used.
RHEOBYK-7405 increases the efficiency of the rheology additive that is being used, and therefore significantly protects the coating system from settling, syneresis and sagging. With RHEOBYK-7405 there is also the possibility to reduce the level of fumed silica or organophilic phyllosilicates without impairing performance. This can reduce negative influences, e.g. on the gloss, while at the same time achieve more cost-effective formulations. RHEOBYK-7405, supplied as a liquid, is easy to incorporate, aromatic- and tin-free. Deaerating and leveling are not negatively influenced.
02.07.2019 - DISPERBYK-2030
DISPERBYK-2030 – High Molecular weight wetting and dispersing additive for solvent-free UV-curable printing inks and inkjet inks. Suitable for all pigment types.
DISPERBYK-2030 is a high molecular weight wetting and dispersing additive based on controlled polymerization technology (CPT) for solvent-free UV-curable inkjet inks and printing inks.
The additive improves pigment wetting and, thanks to its outstanding steric stabilization of the pigments, it also improves the optical properties of the systems (optical density, color strength, gloss, haze, transparency). The viscosity of the pigment concentrates and the finished inkjet and printing inks is reduced and thixotropy is prevented. Additionally, the water and alcohol resistance of the cured film is improved, thanks to the hydrophobic structure of the product DISPERBYK-2030 is compatible with all commonly used reactive diluents and shows no crystallization tendency. Furthermore the additive can be used for indirect food contact applications.
02.04.2019 - RHEOBYK-7610
RHEOBYK-7610 – VOC-, APEO- and tin-free associative thickener for aqueous systems, to generate a highly pseudoplastic flow behavior
RHEOBYK-7610 is an associative thickener for aqueous systems. It generates a highly pseudoplastic flow behavior and considerably increases the viscosity in the low shear range. The most impressive feature, however, is the outstanding self-leveling properties of the finished system. For this reason, alongside good anti-sagging, e.g. at airless/airmix/HVLP application, RHEOBYK-7610 simultaneously offers a perfect surface due to its self-leveling effect. The storage stability and the colorant acceptance have also been improved. Moreover, the foaming behavior of RHEOBYK-7610 is a noteworthy aspect. The additive is liquid and easy to handle. It is not necessary to adjust the pH value or control the temperature during incorporation.
18.03.2019 - RHEOBYK-440
RHEOBYK-440 - Liquid, Polyamide-based Rheology Additive for Modern Aqueous Systems
Over the past years, the focus of developments in protective coatings has increasingly moved to aqueous systems based on epoxy dispersions. These coatings are highly pigmented and applied in thick layers, requiring the rheological properties to be controlled using a suitable additive. The established products are only slightly or even not at all effective, and some are completely incompatible in epoxy dispersions.
The new, polyamide-based RHEOBYK-440, however, is a tailor-made solution for these modern, water-based systems. RHEOBYK-440 does not only provide outstanding anti-sagging and anti-settling properties in water-based protective coatings, it is also recommended for usage in many other applications such as automotive coatings, general industrial coatings, wood and furniture coatings, architectural costings and floor coatings. It can also be used e.g. to achieve a good effect pigment orientation.
12.03.2019 - RHEOBYK-7600
RHEOBYK-7600 - VOC-, APEO- and tin-free associative thickener (HEUR) for aqueous systems, to generate a highly pseudoplastic flow behavior
With RHEOBYK-7600, BYK is offering a unique associative thickener based on a new technology. RHEOBYK-7600 leads to a considerable increase in the viscosity in the low shear range, stabilizes the viscosity when the colorant is added, and improves the color paste acceptance.
The new additive also offers a significantly better leveling properties. As well as being VOC-, APEO-, and tin-free, RHEOBYK-7600 is also liquid, which facilitates incorporation and handling. Due to its composition, it is highly compatible in many aqueous systems. The sagging tendency and the storage stability are improved.
12.03.2019 - BYK-3566
BYK-3566 – Macromer-modified Acrylate with Longer Silicone Chain for a Stronger Increase in the Surface Energy Level
BYK-3566 is the latest addition to BYK´s range of macromer-technology based surface acrylates that provide an increase in the surface energy of dried coatings. The relatively long silicone-macromer chain which is the key characteristic of BYK-3566 causes a powerful orientation to the interface paint/air and thus increases its efficiency to a superior level. In this respect, BYK-3566 shows the strongest effect of all additives of this product family. Additionally, the longer chain provides certain anti-crater properties.
BYK-3566 is recommended for use in aqueous, solvent-borne, UV and 100 % systems.
12.03.2019 - BYK-327
BYK-327 – Silicone-based surface additive for solvent-borne, solvent-free, radiation-curable and aqueous systems, to improve leveling. Defoaming effect in floor coatings.
BYK-327 is a polyether modified-polysiloxane which can be used in aqueous systems, polar solvent-borne systems and in solvent-free systems. It has excellent leveling properties and causes a moderate reduction in the surface tension. BYK-327 has very little effect on foam or even has a defoaming effect, depending on the system. This is due to its balanced polarity. BYK-327 is soluble in most common solvents, as well as in water without causing turbidity. This makes BYK-327 particularly suitable for clear coat systems.
05.03.2019 - BYK-1795
BYK-1795 – Silicone-free Polymer Defoamer for Solvent-borne, Solvent-free and Radiation-curable Systems
BYK-1795 is a silicone-free polymer defoamer for solvent-borne, solvent-free and UV-curable systems. Its spontaneous defoaming action and excellent compatibility mean that BYK-1795 can be used in a variety of applications. BYK-1795 has particularly outstanding defoaming properties in polyurethane and epoxy-based floor coatings, in solvent-borne coil coatings (e.g., PVDF or polyester/melamine), as well as solvent-borne general industrial coatings and UV-curable systems.
29.01.2019 - BYKETOL-WA
BYKETOL-WA – The APEO-free version of BYKETOL-WS
As European regulations on the use of chemical substances will subject the use of one of the active ingredients (APEO) of BYKETOL-WS to authorization in the near future, BYK has decided to design an APEO-free alternative. As to performance, the new BYKETOL-WA is almost identical and can be applied without restrictions.
22.01.2019 - BYK-3450 and BYK-3451
With BYK-3450 and BYK-3451, BYK has developed two new additives based on trisiloxanes, which achieve very good wetting on even the most difficult substrates as well as great spreading capabilities. When compared to conventional silicone surfactants, both additives show less foam stabilization, resulting in an improved processing and application.
