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.

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.

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.

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.

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.

BYKETOL-WA – 不含APEO版本的BYKETOL-WS

由于欧洲法规限制了一些化学物质的使用,比如不久的将来会限制使用BYKETOL-WS中的活性成分APEO,所以毕克化学决定设计一款不含APEO的版本。从性能方面来看,新的BYKETOL-WA几乎和BYKETOL-WS一模一样,而且它的使用不会受到法规限制。
