Packaging Specifications: 20 kg/blue iron drum, 160 kg/blue iron drum. The 20 kg small specification is suitable for small - batch production, laboratory debugging or scenarios with low usage, with flexible handling and storage; the 160 kg large specification is suitable for large - scale industrial production, which can reduce the frequency of packaging replacement, lower unit procurement and logistics costs, and meet the continuous production needs of enterprises.
Core Component: Organosilicon - based substances. With the unique molecular structure of organosilicon, while reducing the surface tension of the system and optimizing leveling properties, it also has efficient defoaming ability, suitable for various coating and resin systems with dual requirements for defoaming and leveling.
Product Performance and Advantages
Integration of Dual Functions: It integrates "defoaming" and "leveling" in one, without the need to additionally match two single - function additives, simplifying the formula system and production process. For example, in the production of solvent - based automotive topcoats, it can not only eliminate bubbles generated during stirring and spraying to avoid pinholes on the paint surface; but also improve the leveling property of the coating, reduce surface defects such as brush marks and orange peel, and enhance the smoothness and aesthetics of the paint surface.
Wide System Adaptability: It can be used in solvent - based coatings (such as alkyd enamel, acrylic topcoat), solvent - free coatings (solvent - free epoxy anti - corrosion paint), powder coatings (coatings for electrostatic powder spraying), as well as polyurethane systems (polyurethane elastomers, polyurethane coatings) and epoxy systems (epoxy floor paint, epoxy adhesive). The applicable scenarios cover two core fields of coatings and resins, and the applicability far exceeds that of single - system additives.
Efficient Optimization of Surface Performance: When used as a leveling agent, it can significantly reduce the surface tension of the coating or resin system, improve the wettability to the substrate (especially for difficult - to - adhere substrates such as plastics and metals), and effectively inhibit Benard swirls (irregular lines formed due to differences in surface tension during coating drying), ensuring a smooth and uniform surface after curing. For example, when powder coatings are sprayed on metal workpieces, it can avoid uneven coating caused by poor wettability and reduce surface defects caused by Benard swirls.
Stable System Compatibility: Although it contains organosilicon components, through special molecular design, it has good compatibility with most solvent - based, solvent - free resins and powder coating carrier resins, and there will be no problems such as turbidity, delamination, affecting curing speed or reducing coating adhesion, ensuring the stable performance of the final product.
Scope of Application and Scenarios
Main Application Fields
Coating Industry: Solvent - based industrial coatings (machinery, equipment coating), solvent - free anti - corrosion coatings (pipeline, tank inner wall anti - corrosion), powder coatings (home appliance shells, building materials spraying), solving bubble and leveling problems in various coating constructions.
Resin and Adhesive Industry: Polyurethane resins (polyurethane elastomer casting, polyurethane sealant), epoxy resins (epoxy floor construction, epoxy potting compound), improving the surface quality and performance of resin after molding.
Typical Application Scenarios
Automotive Parts Coating: In the construction of solvent - based anti - corrosion coatings for metal parts such as automobile wheels and chassis, BYK - A525 can eliminate bubbles in coating stirring and spraying, and optimize leveling properties at the same time, ensuring uniform coating coverage and improving anti - corrosion effect and appearance texture.
Solvent - free Epoxy Floor Construction: The solvent - free system has high viscosity, and it is easy to generate bubbles due to air entrainment during construction, and the leveling property is poor, which is easy to leave roller marks. After adding this additive, it can quickly defoam and improve the leveling of the coating at the same time, creating a flat and flawless floor surface.
Powder Coating Spraying for Home Appliances: In the electrostatic spraying of powder coatings on home appliance shells, it can improve the wettability of the coating to plastic or metal substrates, inhibit Benard swirls, avoid "orange peel texture" on the coating, and make the appearance of home appliances smoother and more delicate.
Usage and Storage Recommendations
Adding Method: The recommended addition amount is 0.1% - 0.5% of the total formula (specifically, it needs to be determined by small tests according to the system type, bubble severity and leveling requirements). It can be added directly during the stirring and mixing stage of coating or resin production. If the system viscosity is high, it can be diluted with a small amount of the corresponding solvent before adding to ensure uniform stirring (stirring time is recommended to be no less than 10 - 15 minutes) to make the additive fully dispersed and exert the best defoaming and leveling effects.
Compatibility Test: When using for the first time or replacing raw materials such as resins, pigments, and curing agents, a small - scale compatibility test is required to observe whether there are problems such as system turbidity, delamination, abnormal curing or reduced coating adhesion, and then apply in batches after verifying the adaptability.
Storage Conditions: It needs to be stored in a cool, dry and well - ventilated environment, avoiding direct sunlight and high temperature (recommended storage temperature is 5 - 35℃), and preventing freezing. The product should be sealed immediately after opening to avoid moisture, oxidation or contamination by impurities; the shelf life of unopened products is usually 12 months, and the performance needs to be retested after expiration to see if it meets the standards.
