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.

10.07.2018 - BYK-3456
BYK-3456 - Fluorine-free, Silicone-containing Additive to Improve Substrate Wetting and Leveling in Aqueous Systems and Solvent-free UV Coatings
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 - 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.
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).
13.02.2018 - BYK-325 N
BYK-325 N – γ-Butyrolactone-free Surface Additive for Solvent-borne Coatings
The new BYK-325 N is equal in performance to well-known BYK-325 but avoids any exports restrictions because it is free from γ-butyrolactone.
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.

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.
