BYK410 Modified Polyurea Rheology Additive For High-density pigments/fillers in industrial coatings
GENERAL DESCRIPTION
Anjeka-4410 is a liquid rheology additive for medium polarity and solvent-free coating systems as well as ambient curing resin systems. The additive produces a highly thixotropic flow behavior and improves anti-sagging and anti-settling properties. This additive can also be added later.
PRODUCT DATA
Chemical composition: Modified polyurea solution.
Typical Physical and Chemical Data:
The data given on this data sheet are typical values and are not product specifications.
Appearance Yellow to brown liquid
Density g/cm³ (23℃): 1.00-1.20
Viscosity cps (25°C): 200-3000
Active ingredient (%): 52
Solvent: N-methyl pyrrolidone
STORAGE AND TRANSPORT
Temperature sensitive, store under dry conditions. Slight turbidity may occur during storage, but it does not affect the rheological effect. The storage time is not recommended to exceed 12 months.
APPLICATION GUIDELINES
Industrial Coatings
Features and Benefits:
When added to the coating system under stirring, the additive will produce a three-dimensional network structure, forming a thixotropic flow behavior ideally suited to prevent settling and anti-sagging properties without affecting leveling.
SPECIAL NOTES
If it is used with drying agents, discoloration may occur, probably due to the formation of metal complexes. Rheological effectiveness in this case should be evaluated.
Under standard dosing, there is no negative effect on yellowing. In suspected systems yellowing and higher additive dosages should be evaluated. When the additive is in reactive and catalytic systems and contains cellulose nitrate, we recommend testing the storage stability of the product.
PVC RESINS
Properties and Benefits
Liquid additives are used in many PVC resins to improve thixotropy, enable faster processing of plastisols during manufacturing, and improve anti-settling behavior and anti-sagging behavior.Anjeka-4410 minimizes color bleeding in pigmented slurries and controls coating set during baking. Increases the stability of PVC foam during mechanical mixing.
RECOMMENDED LEVELS
0.2%-0.5% additives (as supplied) based on PVC resin to prevent settling and color float.
0.5%-1% of additives (supply form) based on PVC resin to prevent sagging.
The above data are empirical and the optimum dosage should be determined through a series of tests.
INCORPORATION and PROCESSING INSTRUCTIONS
This additive should be added to the coating system under medium shear to ensure uniform mixing and rapid dispersion. It does not require specialized temperature control and can be added to the abrasive stage, but is also suitable for post-addition to regulate viscosity. If the additive is suitable for this system, there will be a significant increase in rheology, which depends on time and polarity, and can generally be evaluated 2-4 hours after mixing. This additive is recommended for medium polarity systems.
