BYK Expired Lectures at the European Coatings Show 2017

100% systems and particularly UV-curing coatings are difficult to defoam as a result of their high processing viscosity and lack of solvents. If the formulation also contains matting agents or pigments, defoaming becomes even more challenging. Additionally, demanding application conditions such as quick roller application require instantaneous and efficient defoaming.
As a result of their environmentally compatible and economic formulation, UV and solvent-free systems are popular for wood and furniture coatings, general industrial and other coatings, as well as thermosets.

To take into account the requirements of these systems, two new defoamers with a focus on UV applications have been developed. Depending on the required profile, there is a choice between higher compatibility or greater efficiency, which this presentation will illustrate, considering various application examples and product differentiation criteria.

Conventional polyacrylate-based surface additives are widely used in the paint industry, mainly as leveling agents to improve the appearance of coating systems. Our second generation of polyacrylate-based surface additives uses polyether macromer technology to achieve the very unique effect of increasing the surface energy and thus substantially improving overcoatability. Our latest development, the third generation, now combines the benefit of increased surface energy with anti-crater properties.

Take a look at this unique product and find out what benefits you could obtain for your paint system, regardless if it is a waterborne, solventborne, 100% or radiation curable system.

The needs and requirements of coating formulators and applicators are changing very dynamically in the field of waterborne coatings. A modern waterborne coating is expected to be similar or even better in workability than solventborne systems. In addition, the regulatory aspects such as tin-free SVOC / VOC are tremendously important when such new waterborne system need to be developed. BYK´s approach in developing a new class of rheology modifiers in order meet these ambitious needs and requirements is discussed during this presentation.

Silicone additives have long been used in the coatings industry because they provide a range of superb properties, including reduced surface tension and therefore very good substrate wetting, anti-crater properties, increased surface slip, scratch resistance, and very good leveling properties. These effects can be achieved by using low additive dosages. Strong and effective polysiloxanes are not free from side effects: such products exhibit side effects, such as foam stabilization, when very strong and active silicones are used.

The market is also facing an increasing number of regulatory challenges. For example, polysiloxanes can contain cyclotetrasiloxanes, such as octamethylcyclotetrasiloxane (D4), which is already classified as reproductive toxicity cat. 2, and decamethylcyclopentasiloxane (D5) in small traces.
BYK-3760 is a highly active polysiloxane with excellent surface properties. The composition of this product is unique and, despite its high activity, it exhibits very little impact on foam stabilization. Furthermore, it is a product where cyclotetrasiloxanes have been removed.

By using wax additives, a wide range of properties can be adjusted. Waxes can provide a permanent surface protection or provide hydrophobicity. They are used for COF control as well as gloss adjustment.These properties are influenced by particle size distribution and wax base. The presentation will give an overview of the BYK portfolio for:

  • Waterborne and solventborne liquid printing inks
  • Waterborne inkjet inks
  • Offset inks
  • UV inks

For decades, polymer technology has provided the construction sector with high-performance leveling systems. The 3K-PU self-leveling systems exhibit outstanding physical and chemical resistance, having been designed for industrial applications, particularly for use in the food & beverage industry.
The use of liquid defoamers in the binder is state of the art to obtain good application, self-leveling, and surface performance. However, considering its short pot life, the defoamer used has to be very effective in order to achieve good defoaming properties in the final formulation. In other words, the defoamer has to be very incompatible with the binder, quite often resulting in phase separation issues. A more compatible defoamer, on the other hand, helps to suppress phase separation but frequently is not efficient enough to affect the performance in terms of leveling and surface appearance.
BYK will be showcasing a novel defoaming concept by introducing BYK-066 N as a liquid defoamer in the binder and BYK-1690 SD as a highly efficient solid defoamer in the powder part. This new approach enables the formulator to develop new 3K-PU leveling systems with enhanced overall performance.

Waterborne coatings and efficient corrosion protection are characteristics that still often contradict each other. New DISPERBYK-2080 and DISPERBYK-2081 will significantly improve the corrosion protection of coatings and are therefore perfectly designed for waterborne primers. These products are dedicated wetting and dispersing additives for anti-corrosive paints.  But coatings with DISPERBYK-2080 and DISPERBYK-2081 demonstrate perfect stain resistance as well! This makes these products interesting not only for anti-corrosion primers, but also for waterborne Top Coats when stain resistance is required.

Speaker: Heiko Juckel, Global Head of End Use Marine & Protective Coatings

Before joining BYK-Chemie in 1993, Heiko Juckel studied chemistry and completed an MBA degree. He is the BYK contact for additives in the global marine and protective coatings market. His experience in the coatings industry over the past 25 years has made him a networker and a valuable partner for the branch, whether it be for new developments or for customer projects.
The market is facing more and more regulatory challenges, where BYK, as a leading additive supplier, needs to respond proactively and where older product groups no longer meet the current requirements. The list of topics under discussion is long: tin-free, VOC / SVOC, halogen-free, PAH-free, D3–D5 cyclotetrasiloxanes, and many more. Due to REACH, many substances are re-evaluated and re-classified. Surface additives are often based on polysiloxanes. These could contain cyclotetrasiloxanes, such as D4 (octamethylcyclotetrasiloxane), which is already classified as reproductive toxicity cat. 2, and D5 (decamethylcyclopentasiloxane) in small traces. These substances are suspected of being persistent, bio-accumulating, and toxic. In addition, these products are volatile. The presence of these cyclotetrasiloxanes has a negative impact on the eco-label in architectural coatings and also a negative impact on the food contact classification of products. BYK has developed special technology for removing these substances almost completely.

BYK´s approach to cyclotetrasiloxanes is discussed during this presentation.

UV curing technology is one of the fastest-growing coatings technologies with disproportional growth rates annually and globally. Recently, there has been an ongoing trend for wood and furniture coatings toward the development of deep matt 100% UV-curing systems, which is a challenging task and requires tailor-made raw material selection as well as well-suited application and curing equipment. Besides specially designed matting resins or agents, the use of solid particles such as non-treated or treated silica is common practice when it comes to reducing gloss significantly. However, the absence of volatile solvents, minimal film shrinkage, and the high curing speed of 100% UV-curing coatings require high silica matting agent loading, resulting in a tremendous viscosity increase in the coating systems.

To meet the demanding technical requirements and overcome the stress field between the necessity of high silica matting agent loadings on the hand and excellent formulation and application viscosity on the other, a specially designed wetting and dispersing additive has been developed. This product is perfectly tailored to interact with untreated and treated silica matting agents in 100% UV-curing coatings, resulting in excellent viscosity reduction and deeply and homogeneously matt coating surfaces, which will be shown in this presentation using different application examples.

To protect surfaces against natural impact has been the target of this product development.
BYK-SILCLEAN 3701 can be integrated into the binder matrix to achieve long-lasting effects. Paint surfaces will get an easy-to-clean character and be protected against mechanical stress. Originally developed for 100% epoxy binders systems, the product can be used in solvent or high-solid epoxy systems as well. A product which seems to be simple in the beginning, but which turns out to be very efficient in the end!

Today's coatings technology is driven by a number of technical and commercial challenges. Additives being important ingredients in the formulation of coatings can be advantageously used to valorize the related materials and advance the technology. Surface properties - such as leveling, slip, ease of cleaning, recoatability, hydrophobic or hydrophilic properties - are strongly influenced by the surface-active additives. These additives segregate toward the coating-air interface and tailor the surface properties. The performance and properties that these additives attribute to the coating depend on their chemical compositions and their structures. This presentation will update sophisticated additive technologies, with their highly structured polymer architectures derived from the macromonomer technology.
