Polymeric Wetting and Dispersing Additive for Aqueous Systems

DISPERBYK-199 is the first VOC-free wetting and dispersing additive to use electrosteric stabilization  and to combine the increased quality requirements and the demand for greater efficiency. It therefore represents a good alternative to the polyelectrolyte-based dispersing additives or the high
molecular weight wetting and dispersing additives which are often used in aqueous systems. DISPERBYK-199 is ideal for inorganic and organic pigments, and particularly recommended for water-based coatings (PVC 16–35) and highly filled pigment concentrates.

Benefits

  • Cost-effective alternative to commonly used dispersants (e.g. Na+ and NH4+ salted polyacrylic acids) and high molecular weight wetting and dispersing additives in aqueous systems
  • Same stabilization mechanism in pigment concentrates and base paints > perfect stabilization and color acceptance
  • Introduces no VOC into paints and pigment concentrates (TVOC < 1500ppm)
  • APEO- and amine-free

VOC-free Wetting and Dispersing Additive for High-Quality Pigment Concentrates

DISPERBYK-2015 is a specialist for high-quality, aqueous pigment concentrates, which was developed based on CPT (controlled polymerization technology). This technology enables a close, defined molecular weight distribution that guarantees an application in many different binder systems. DISPERBYK-2015enables a high level of gloss and exceptional color strengths with optimum viscosity and good leveling properties. 

Benefits

  • Excellent compatibility in a wide range of water-borne resin systems due to narrow molecular weight distribution
  • Good stabilization and deflocculation of organic and inorganic pigments
  • Improves gloss and reduces haze
  • Strong reduction of millbase viscosity allows high pigment loadings
  • VOC-free

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.

Benefits

  • Perfect defoaming with no or minor effect on optical properties
  • Broad compatibility with various systems (clear, matted, pigmented)
  • Easy to incorporate
  • Particularly suitable for use in airless/airmix applications
  • VOC- and APEO-free
  • Ecolabel-compliant

VOC-free Silicone-containing Defoamer for Aqueous Wood, Architectural and Industrial Coatings.

BYK-093 is an additional VOC-free silicone-containing defoamer for aqueous wood, architectural and industrial coatings. It is all-purpose and therefore excellently suited as a standard defoamer in the formulation of aqueous systems. Due to its balanced compatibility, it causes virtually no surface defects such as cratering or fogging. BYK-093 can be used both in pigmented and non-pigmented coatings, and is particularly recommended for contemporary, co-solvent-free binders which form the basis of VOC-free or low-VOC formulations. BYK-093 also supports the excellent long-term stability of the finished coating (both at high as well as low temperatures), is easy to incorporate, and suitable for all standard types of application.

Benefits

  • Environmentally friendly defoamer
  • Excellent long-term efficiency (at high and low storage temperatures)
  • Very compatible, and therefore less surface defects (e.g. turbidity, cratering)
  • Easy incorporation, post-addition recommended
  • Combinations with other defoamers possible
  • Broad application profile
    • Brushing
    • Rolling
    • Flow coatings
    • Curtain coatings
    • Vacumat
    • Spraying

Highly Effective Silicone Additive for Aqueous, Solvent-borne, and UV-curing Systems

BYK-3760 is a unique, highly active polyether-modified polysiloxane. As a result of its low tendency to stabilize foam, BYK-3760 can also be used in applications that involve high shear forces. The additive remains fully effective, even at a very low dosage. At the same time, its outstanding compatibility means that it can be used in a wide variety of resin systems. BYK-3760 is the first representative of a series of new silicone additives that run through an additional production step in which virtually all cyclic siloxanes are removed (D4–D6). As a result, BYK-3760 corresponds to the latest requirements of common ecolabels such as EU Ecolabel, Nordic Swan, Blauer Engel, as well as the specifications for use in food contact applications. BYK-3760 is a modern, highly effective, and universal silicone additive which is produced according to the latest BYK technology standards and recommended for usage in

  • General industrial coatings
  • Wood and furniture coatings
  • Can coatings
  • Architectural coatings
  • Protective coatings
  • Printing inks

Benefits

  • Extremely strong reduction in surface tension

    • excellent anti-cratering properties
    • improved substrate wetting
    • high surface slip – low COF values
    • good scratch resistance

  • Extremely low foam stabilization ⇒ significantly better than standard additives
  • Extensive compatibility in a wide variety of systems ⇒ universal
  • 100 % solid content ⇒ complies with the strict ecolabel requirements; labeling-free

Fluorine-free, Silicone-containing Additive to Improve Substrate Wetting and Leveling in Aqueous Systems and Solvent-free UV Coatings

Efficient substrate wetting and outstanding leveling are not guaranteed in every system nor are they easy to achieve. A particular challenge is posed by aqueous systems owing to the high surface tension of the medium, and UV systems, which are critical based on their rapid curing and high application speeds. It is for these specific systems that BYK has developed BYK-3456. It 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. And there is no negative impact on the recoatability of the system. The additive is compatible with a multitude of resins and stable to hydrolysis across a broad pH range. This is why it is recommended for so many applications:

  • Wood & furniture coatings
  • Architectural coatings
  • General industrial coatings
  • Protective coatings
  • Leather coatings
  • Printing inks
  • Inkjet inks
  • Adhesives
  • Household, industrial and commercial cleaners

Benefits

  • Excellent substrate wetting even on porous substrates, e.g. wood
  • Improved substrate wetting combined with good leveling properties
  • Reduction in the dynamic surface tension
  • Hydrolytic stability at low and high pH values
  • Eliminates craters, fish eyes and picture framing
  • High compatibility with many resins
