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 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

BYK-3450 and BYK-3451 – Silicone Surfactants for Aqueous Systems with a Significant Reduction in Surface Tension and Improved Wetting on Highly Non-Polar Substrates, without Increasing Surface Slip

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.

27.11.2018 - BYK-1786

BYK-1786 – VOC-free Silicone Defoamer for Aqueous Systems to Remove the Application-related Microfoam

In 2017, BYK introduced the BYK-1781 additive in order to reduce the occurrence of microfoam in the coating resulting from difficult application methods such as spray painting (HVLP), airless and airmix applications. The new BYK-1786 is the emulsion of BYK-1781. In this form, the additive is easier to incorporate and dose. BYK-1786 is particularly recommended for pigmented and unpigmented architectural, general industrial, protective, wood and furniture coatings, as well as floor coatings, adhesives, sealants, care products and polishes. The additive is VOC- and APEO free and has no impact on transparency, haze, and cratering.

26.09.2018 - BYK-1796

BYK-1796 - Highly Effective Air Release Agent for Solvent-free and Solvent-borne Systems

In many areas, high-solid or 100 % systems make a valuable contribution to reducing or avoiding solvent emissions. One big challenge comes in releasing all of the air from these systems. BYK-1796 is a newly developed air release agent that guarantees fast and efficient elimination of trapped air without altering optical and mechanical properties. The high efficiency of the additive and a good price-performanceratio make it the number one choice for solvent-free systems. One such application example comes in the form of PU or EP floor coatings. BYK-1796 is also recommended for solvent-based systems, e.g. protective coatings, where it also offers a full range of services.

BYK-3456 is a fluorine-free silicone additive that greatly reduces the dynamic and static surface tension. Even rough and porous substrates (e.g. wood) are wetted perfectly. As BYK-3456 is active both at the interface to the substrate and at the surface, the additive simultaneously improves substrate wetting and leveling. In contrast with many other additives, however, BYK-3456 does not stabilize foam.

26.06.2018 - DISPERPLAST-1180

DISPERPLAST-1180 Low-volatile and solvent-free wetting and dispersing additive for filled, plasticizer-containing PVC dryblends/compounds

The new DISPERPLAST-1180 is a very efficient wetting and dispersing additive for highly filled systems in which conventional processing aids and standard wetting and dispersing additives reach their limits. Quite regularly, the filler content in formulations is increased in order to improve the efficiency causing undesirable effects. The use of DISPERPLAST-1180, however, does not only facilitate reducing the formulation costs by increasing the filler content, it also improves the quality of the end product. DISPERPLAST-1180 is therefore particularly suitable for high-quality laminated systems such as PVC design floorings (LVT).

26.06.2018 - AQUACER 583

AQUACER 583 Wax emulsion to improve the surface characteristics of seed coatings

Seed coatings are the current standard in agriculture. The reasons for this are many. An applied protective film prior to use increases the productivity on-site through better processing conditions and higher protection against outside influences. AQUACER 583 is a new non-ionic wax emulsion for aqueous seed coatings. The additive improves the abrasion resistance, the free-flowing and plantability of the seeds. Additionally AQUACER 583 hat a positive impact on gloss and anti-blocking properties.

13.02.2018 - BYK-1166

BYK-1166 Wetting additive for PVC plastisols to reduce the viscosity in the low shear range
Currently not available in North America

The new BYK-1166 is the latest development within the BYK-1160 series. All of these products work very effectively to reduce the low shear viscosity of PVC plastisols based on pseudo-plastic PVC grades. Occasionally, in PVC plastisols containing azodicarbonamide (AZO) as a blowing agent, the additives of the BYK-1160 family can cause yellowing in the final product. This is a limiting factor – especially in the wallcovering industry. BYK has therefore developed BYK-1166 which has been evaluated within the European PVC foam resins most widely used in the industry. The latest member of the BYK-1160 family has low volatility and can be used in a wide range of PVC applications (except low fogging for automotive). It is especially recommended for chemically foamed PVC plastisols where white index and surface properties are of importance. BYK-1166 shows the best heat stability of all products within the BYK-1160 family.

06.02.2018 - BYK-C 8013

BYK-C 8013 Solvent-free, polymeric coupling agent to increase the mechanical strength of carbon fiber-reinforced, radical-curing systems

BYK-C 8013 is the world’s first coupling agent for carbon fibers. It is used in vinyl ester and unsaturated polyester resins that will be subsequently processed with carbon fibers into composite components. Strengths transverse to the fiber are considerably increased and therefore enable a greater design freedom. The improved fiber-matrix bonding in BYK-C 8013 increases both the transverse tensile strength as well as the flexural strength of the composite. The chemical composition of the additive enables bonding to the fibers and simultaneously to the resin matrix. This unique characteristic allows changes in the component design and the production of more resilient parts. BYK-C 8013 shows a considerable increase in mechanical strengths up to 70% particularly in hot curing processes such as SMC/BMC, Pultrusion, Prepreg or RTM. The reactive additive can be added to the sizing during the fiber production or to the resin shortly before processing.
As a subsequent so-called “second sizing”, BYK-C 8013 can be applied onto the fiber, for example by spraying, without having to remove the first sizing beforehand. BYK-C 8013 is recommended for all carbon fiber types.

09.01.2018 - DISPERBYK-2157

DISPERBYK-2157 VOC- and solvent-free wetting and dispersing additive for non-polar systems

DISPERBYK-2157 is a VOC- and solvent-free wetting and dispersing additive for non-polar solvent-borne and solvent-free inkjet inks, printing inks, protective and architectural coatings as well as PVC plastisols. The additive is excellent compatible with solvents, like paraffins, isoparaffins, vegetable oils, mineral oils or plasticizers. DISPERBYK-2157 is recommended for all kinds of pigments and greatly improves optical properties such a color strength, transparency and gloss. In inks and coatings applications DISPERBYK-2157 provides a strong reduction of the mill base viscosity and a good stability. In PVC applications the additive shows a strong decrease of batch and final plastisol viscosity and moreover offers an excellent heat stability.
