Chemical Composition: Polyether - modified polydimethylsiloxane (fluorine - free).
Core Functions:
Significantly improve the substrate wettability of water - based coatings and solvent - free UV coatings, and enhance the leveling effect of the coating.
Prevent surface defects such as craters and fisheyes, enhance the uniformity of the coating, and be suitable for difficult - to - wet substrates (such as metals and plastics).
It does not affect the gloss of the coating and has good recoatability.
Application Fields
Main Scenarios:
Water - based coatings: architectural coatings, industrial coatings, wood coatings, etc.
Applicable Substrates: metals, plastics (such as ABS, PVC), glass, wood, etc.
Recommended Dosage and Usage Methods
Dosage: 0.1% - 0.5% based on the total formula (calculated by the purchased form), and the specific dosage needs to be adjusted according to the system.
Adding Method:
It can be added at any stage of the production process, and it is recommended to add it slowly under low - speed stirring.
When used in UV systems, it is necessary to ensure compatibility with photoinitiators to avoid affecting the curing performance.
Storage and Transportation
The recommended storage temperature is 5 - 40°C, avoiding freezing or high temperature, and the shelf life is 60 months.
It is handled as a non - dangerous goods during transportation, avoiding direct sunlight and severe vibration.
Competitive Advantages
Comprehensive Performance: It can efficiently improve wettability and leveling in both water - based and UV systems, especially suitable for difficult - to - wet substrates. It solves the problem of craters without affecting the gloss of the coating.
Process Compatibility: 100% active ingredient (solvent - free), has strong compatibility with water - based and UV curing processes, and can be added later to adjust performance, with flexible operation.
Environmental Compliance: It does not contain fluorine elements, meets environmental regulations, and is suitable for coating systems with higher environmental requirements.
High Cost - Effectiveness: A small amount of addition can achieve significant effects, reduce formula costs, and improve the qualification rate of finished products.
Technical Support: BYK provides professional formula optimization suggestions and after - sales technical services to ensure that customers obtain the best use effect.
