Evaluation method using the RCA wear testing machine (Wazau test) - Two samples coated on a glass plate are evaluated. A paper with abrasives is pulled across the coating surface with a constant pressure. After pulling for 10 cm, the coating is completely scraped off. In systems where wax is blended to improve abrasion resistance, the distance increases from 10 cm to 80 cm. At 10 cm, almost no wear is observed, while at 80 cm, the condition is better than that of the control at 10 cm.

Using two cans to demonstrate the role of foam paint: one can is coated with regular direct metal paint and the other with fire-resistant foam paint. The cans are stacked with metal blocks to apply pressure, allowing flames to reach the paint film. The regular paint film deteriorates until the can bursts, and high temperatures weaken the metal, while the foam paint prevents the can from bursting through expansion and the formation of char.

Behavior of polysiloxane-based additives in three different solvents - After shaking three types of solvents (ethanol, xylene, butyl acetate), no foam remains. A certain amount of silicone-based additive (BYK-323) is added to each solvent. After shaking, the left bottle is cloudy, the middle bottle is clear but foams strongly, and the right side is clear with no foam. The effectiveness of silicone-based surface modifiers strongly depends on the compatibility in the solution state.

Expansion of Applications for Thermoplastic Resins - Polymers Our products are suitable for a wide range of plastic materials, including polyolefins and engineering plastics. In addition to processing aids, new coupling agents, and modifiers like BYK and SCONA, BYK-MAX and POLYAD products play a major role in the applications of thermoplastic plastics. Most of them are designed specifically for these purposes. Functional additives are used to achieve many physical properties and have become essential in today's cutting-edge applications of thermoplastic plastics in the automotive and electrical/electronic industries. These properties include weather resistance, heat resistance, flame retardancy, crystallization, and drying properties. Additionally, there are additives that provide effects such as anti-fogging, scratch resistance, and antistatic properties. - Five product brands for thermoplastic resins

Without the wetting dispersant, there is strong aggregation, resulting in large agglomerates and a lack of hiding power. With the wetting dispersant, the fine particles are well de-agglomerated and deflocculated, achieving excellent hiding power and high gloss. Lobout test; When mixing multiple pigments or particles, if the pigments are not sufficiently stable, separation occurs. This issue is referred to as color floatation/color separation, and it can be observed as a color change when performing the lobout test (rubbing the lower part of the paint film with a finger). The pigments are stable with BYK wetting dispersant, and no separation of pigments occurs.

Samples without additives show poor wetting (beading). The samples contain BYK polysiloxane additives that reduce surface tension, resulting in improved wettability on the substrate. Aggregation and de-aggregation of red pigments; The pigment dispersion was prepared without the wetting dispersant additive. The pigments strongly aggregate, and large clumps are clearly visible. In the second dispersion, the pigments are fully stabilized by the appropriate BYK wetting dispersant. As a result, the pigments are completely de-aggregated, and large particles are no longer visible.

The paint is flowed onto a vertically positioned (slightly inclined) polyester film. The difference in foam stability is clearly visible between the sample on the left (without defoamer) and the sample on the right (with BYK defoamer). Wetness of Pigments; Organic pigment (Phthalocyanine Blue) is added to water. The pigment remains floating on the surface of the water and does not get wet (the process is very slow, and wetting is not visible). When BYK additive droplets are added, the organic pigment becomes instantly wet. The speed of pigment wetting dramatically improves.

Coil application (with stirring / without stirring) test; This is a testing method that evaluates the stability of pigments through a lab-out test by blending the paint just before application. The paint sample is stored at room temperature overnight and then divided into two parts. One is stirred for 1 minute at 6 m/s using a serrated blade (this simulates the high shear stress in a coil coating line during application). The other is not stirred. Both are applied side by side on a panel using a wire bar coater. A color difference is observed between the stirred and unstirred samples. Next, a lab-out test is conducted, where a color difference is also evident. Then, the panel is baked (320 °C, 30 seconds). Poor performance of the paint is due to insufficient stability of the pigments. The same procedure is repeated with another paint sample where the pigments are fully stabilized by additives. In the lab-out test, no color difference is observed between the blended and unblended samples (or the difference is minimal).

BYK-329 is a silicone-containing surface additive for both solvent-free and solvent-based systems. It significantly reduces surface tension in floor and general industrial coatings, improving leveling and defoaming properties. Additionally, as a defoamer, we have launched the new VOC-free silicone-containing additive BYK-092 for water-based paints, printing inks, and adhesives. Effective BYK defoamers for a wide range of applications BYK-092 is a highly effective defoamer, particularly for water-based clear coats and high-gloss systems. It also performs excellently in matte and pigment systems. Due to its balanced compatibility, this product does not affect transparency or gloss. BYK-092 is effective not only in general applications but also in challenging applications such as HVLP and roller coating. This additive can be added at any stage of production. User-friendly surface additive BYK-329 significantly reduces surface tension in paint coating systems, affecting leveling and defoaming properties. This product enhances substrate wetting and is particularly effective in two-component epoxy resin systems for floor coatings.

Phthalocyanine blue and titanium dioxide blue paint. When observed under a microscope, Benard cells can be confirmed. Material rises from the center of the cell to the surface, then flows along the surface and sinks back into the interior at the periphery of the cell. In this system, the pigment particles are not sufficiently stabilized, and due to this strong flow in the cell, the two pigment particles separate. The mobilities of the white and blue pigment particles are different, leading to their separation at the cell periphery. - Blue paint de-foaming test; Defoam the foam of the water-based blue paint with a defoamer. Shake the blue paint in the container. The foam disappears with the addition of the defoamer.

One does not contain a surface modifier. The other contains BYK-3565. Due to the increase in surface free energy from BYK-3565, the water droplet spreads significantly. After the water is dropped, the contact angle rises to 60 degrees for both, but due to the interaction between the water and the panel surface, the system with BYK-3565 retains the water droplet. - Leneta PVC Big Chemie BYK-333 and BYK-346; Wettability spreading of water on PVC Leneta foil. Comparison of BYK-333 and BYK-346 Water droplets are dropped on two PVC foils. The wettability of the water droplets is poor and does not spread. Two types of silicone-based additives (20 µl) are added to the water droplets. BYK-333 and BYK-346. The silicone surfactant BYK-346 is more active than the polymer-type silicone additive BYK-333, resulting in greater expansion and spreading of the water droplets.
