Packaging Specifications: 25 kg/blue iron drum, 200 kg/blue iron drum
Chemical Composition: A high - molecular - weight ammonium salt copolymer
Product Features
Multi - system Applicability:As a solvent - free wetting and dispersing additive, it can be used in solvent - based coatings, solvent - free coatings, adhesives, PVC plastisols and room - temperature curing resin systems. It is also suitable for the production of thermoplastic plastics (such as PE, PP, ABS, PVC, PET, PA) and color masterbatches. Its chemical structure can adapt to the polarity differences of different systems and can play a stable dispersing role in both solvent - based and solvent - free environments.
Efficient Prevention of Phase Separation and Fiber Wetting:It can prevent phase separation problems in the system. Especially in SMC/BMC (Sheet Molding Compound/Bulk Molding Compound) formulations, it can improve the wetting performance of glass fibers, reduce fiber agglomeration, and enhance the mechanical properties and molding stability of composite materials.
Optimized Dispersion for Carbon Black Pigments:It is especially recommended for acidic and neutral carbon black pigments. Through the electrostatic repulsion and steric hindrance effects of the high - molecular - weight ammonium salt copolymer, it can effectively break the aggregates of carbon black, improve its dispersion uniformity in the system, and avoid problems such as uneven color and increased viscosity caused by carbon black agglomeration.
Broad Spectrum Pigment Compatibility:It is suitable for various pigments (including organic pigments and inorganic pigments), and has outstanding performance in systems with high stability requirements. It can improve the tinting strength, hiding power and storage stability of coatings, plastics and other products.
Application Fields
Coatings and Adhesives:
Solvent - based industrial coatings (such as metal anti - corrosion paints, automotive refinish paints): Improve pigment dispersion and enhance coating gloss and weather resistance.
Solvent - free adhesives: Enhance filler dispersion and improve bonding strength and construction fluidity.
Thermoplastic Plastics and Color Masterbatches:
Used in the production of color masterbatches for plastics such as PE and PP to ensure uniform dispersion of pigments and avoid color streaks or performance defects in plastic products.
In PVC plastisols, it can reduce system viscosity and improve processability.
Composite Materials:
SMC/BMC formulations: Optimize the interface bonding between fibers and resin, and improve the mechanical properties and surface quality of FRP products.
Recommended Dosage
The dosage needs to be adjusted according to the specific system and pigment type (based on the percentage of pigments in the system in the purchased form).
It is generally recommended to determine the optimal addition amount through small - scale tests. For example, in a carbon black system, the dosage can be gradually increased until the dispersion effect meets the standard, while avoiding excessive dosage that causes viscosity to increase.
Addition Method
In the production of coatings or plastics, it is recommended to add BYK - 9076 in the pigment pre - dispersion stage.
Solvent - based system: First mix the dispersant with the solvent, and then add the pigment for grinding;
Solvent - free system: Directly mix with resin and pigment and then stir for dispersion to ensure that the dispersant is fully in contact with the pigment.
Storage Conditions
Store in a cool, dry and ventilated warehouse, avoid direct sunlight, and the recommended storage temperature is 5 - 30 °C.
The viscosity may increase in a low - temperature environment. Before use, it needs to be restored to room temperature and fully stirred, which does not affect the product performance.
