Packaging Specifications: 25 kg/blue iron drum, 185 kg/blue iron drum
Chemical Composition: Low molecular weight unsaturated polycarboxylic acid polymer solution
Product Characteristics
Appearance and Physical Properties: Generally appears as a colorless to light yellow transparent or slightly yellow transparent liquid with a slight special odor. The density is typically in the range of 0.9 - 1.1 g/cm³ (at 20℃), and it has a relatively high flash point, ensuring safety during storage and transportation. It has good solubility in common medium to high polarity solvents and can be uniformly dispersed in solvent - based coating systems.
Core Functions
Controlled Flocculation: As a controlled flocculation type wetting and dispersing agent, it can make pigment particles form a controllable weak flocculation state. This state maintains the dispersion stability of pigments during coating storage and prevents precipitation; under the action of shear force during coating application, the flocculation structure is destroyed, and pigments can be uniformly dispersed. After application, a weak flocculation can be re - formed to prevent floating and blooming.
Prevention of Floating and Blooming: Especially for the case of titanium dioxide being mixed with colored pigments, it effectively prevents the separation phenomenon of different pigments caused by differences in surface properties, particle sizes, etc., ensuring uniform color of the coating and improving the appearance quality of the coating film.
Improvement of Pigment Dispersibility: It enhances the wettability and dispersibility of pigments in solvent - based medium to high polarity coating systems, reduces the possibility of pigment agglomeration, enables pigments to better exert their tinting strength and hiding power, and reduces pigment consumption.
Application Fields
Main Application Scenarios
Automotive Coatings: Used in original automotive paints and automotive refinish paints to formulate coatings of various colors, ensuring color uniformity and consistency and improving the appearance quality of automobiles.
Industrial Coatings: Such as metal protective coatings and mechanical equipment coatings, to ensure uniform coating color and improve the decorative and protective properties of the coatings.
Wood Coatings: Used to formulate wood paint colors, prevent color unevenness, and make the surface of wood present a beautiful and uniform color effect.
Applicable Coating Systems: Suitable for solvent - based medium to high polarity coating systems such as alkyd resins, acrylic resins, and polyurethane resins.
Recommended Dosage and Usage Methods
Recommended Dosage: Based on the amount of pigments in the coating formula, the dosage is usually 0.5% - 3% (calculated by the purchased form). The specific dosage needs to be adjusted according to the coating system, pigment type, and actual requirements.
Usage Methods: During the coating production process, it is recommended to add BYK - P104 in the grinding stage and perform dispersion and grinding operations together with pigments to ensure that the dispersant is fully adsorbed on the pigment surface and exerts the best dispersion and anti - floating and blooming effects. It can also be added in the paint mixing stage, but it needs to be fully stirred to ensure that the dispersant is fully mixed with the coating system.
Storage and Transportation
Storage Conditions: The recommended storage temperature is controlled at 5 - 35℃, and the storage environment should be dry, ventilated, and away from direct sunlight and heat sources.
Shelf Life: Under proper storage conditions, the shelf life is usually 60 months.
Transportation Requirements: Transport as general chemicals, avoiding severe impact, extrusion, and inversion during transportation to prevent packaging damage and product leakage.
