★Digital Printing Digital printing has become more widespread and common in the creation of decorations on coated fabrics and genuine leather. It is necessary to optimize the receptivity of water-based printing inks on PU or PVC substrates. The 【BYK-356X Series】 is effective. BYK-3560 BYK-3565 BYK-3566

★The Importance of Rheology in High Solid Content Polyurethane Formulations High solid content polyurethane (HS PU) is gaining popularity as an alternative to solvent-based systems (DMF coagulation process) and PVC plastisol. HS PU often exhibits relatively high viscosity at room temperature, but it has been observed that when cured in a high-temperature oven at 150-170°C, the viscosity significantly decreases. This phenomenon can potentially affect leveling properties and foaming ratios when using chemical blowing agents. By using 【GARAMITE】, it is possible to suppress the viscosity decrease in the oven. Overview of 【GARAMITE-1958】 - Pseudoplastic - Suitable for solvent-based and solvent-free systems - No polar activation required - Non-dripping - Patented - Allows for easy and rapid formulation

★Sustainable Bio-Based Wax-like Polymers @BYK-CERAFLOUR-1000 Series Manufactured from renewable raw materials. 【CERAFLOUR 1000】 A biodegradable micronized polymer with wax-like properties derived from renewable raw materials. Suitable for water-based, solvent-based, solvent-free, and UV systems. Aims to enhance surface protection and soft touch effects, as well as matting. Improves surface protection and soft feel effects. 【CERAFLOUR 1003】 A starch-based polymer that achieves slight surface texture and optimal transparency. Provides excellent matting effects from different angles. 【CERAFLOUR 1004】 Achieves subtle matting effects and high transparency through a fine particle structure. A starch-based polymer that delivers a smooth, soft, and silk-like texture.

★Hydrophilicity in High Solid Content Polyurethane Compositions High solid content polyurethane (HS PU) is gaining popularity as an alternative to solvent-based systems (DMF coagulation process) and PVC plastisol. The potential applications of HS PU include the manufacturing of coated fabrics for footwear and clothing. To provide comfort and optimal performance during sports activities, it is important to absorb moisture generated by the body. 【BYK-P 9911】 enhances hydrophilicity and moisture absorption. 【BYK-P 9911】 Features - Hydrophilic additive: High compatibility with HS PU and PUD - Improved moisture absorption enhances comfort during sports activities.

★High Solid Content PU Technology BYK-3760 ・ BYK-L 9565 – Substrate Wetting Properties High solid content PU systems require additives that appropriately adjust the wetting and leveling properties of the substrate. In the automotive industry, low fogging and low VOC are required. 【BYK-3760】 Significantly reduces the surface tension of the coating system. Therefore, it particularly improves the wetting properties of the substrate and prevents crater-like defects. BYK-3760 greatly enhances surface slip and improves the scratch resistance of the coating. This product has far less foam stabilization effect compared to other highly active additives containing silicone. It is effective even at low addition levels. 【BYK-L 9565】 BYK-L 9565 improves the wetting and leveling properties of release papers. It can be used universally regardless of the type of coating or the pattern of the release paper. Due to its -OH functional group, this additive is reactive to isocyanates, minimizing the risk of migration and providing lasting properties.

★Release paper surface modifiers and defoamers In recent years, the transition from solvent-based to water-based systems has gained significant importance. In water-based systems, the following issues frequently arise: • Low wettability of release paper • Entrapment of bubbles BYK-349 and BYK-093 are examples of additives that can solve these problems. 【BYK-349】 A silicone-based surfactant with a significant ability to reduce surface tension, improving the wettability of the substrate. It does not contribute to improved slip properties on the surface. Suitable for systems that do not contain co-solvents. General-purpose product. 【BYK-093】 Water-based defoamer • Applicable to a wide range of uses • Excellent long-term stability (during high and low-temperature storage) • Fewer surface defects (cloudiness, crater-like defects, etc.) due to high compatibility • Easy to mix, recommended for post-addition • Can be used in combination with other defoamers • APEO-free, formaldehyde-free (VdL RL-03), low VOC

Barrier clay to prevent migration of various additives in plasticized PVC • BYK's high aspect ratio synthetic hectorite exhibits excellent barrier performance against the migration of undesirable substances such as plasticizers and hydrocarbons from PVC plastisol. • BYK's high aspect ratio synthetic hectorite minimizes the impact on the color tone and haze of the film. • BYK-3410 (silicone-free leveling and substrate wetting additive) and BYK-014 (silicone-free defoamer) enhance the barrier effect and are essential for optimal processing.
