Anjeka 4410 Prevents settling and sagging No adverse effect on gloss and leveling
DESCRIPTION
Anjeka-4410 is a liquid rheology additive designed for medium-polarity and solvent-free coating systems, as well as ambient-curing resin systems. It imparts highly thixotropic flow behavior, improving anti-sagging and anti-settling properties. The additive can also be introduced at a later stage of production for viscosity adjustment.

STORAGE AND TRANSPORT
This product is sensitive to temperature and should be stored in dry conditions. Any slight cloudiness observed in the material during storage does not affect its ability to control flow properties.
Application
Industrial Coatings
When added to a coating system and mixed thoroughly, this additive forms a three-dimensional network structure. This creates a thixotropic flow pattern that effectively prevents particle sedimentation and improves anti-sagging properties, all while maintaining smooth leveling.
Special Notes
Use with drying agents: Discoloration may occur, possibly due to the formation of metal complexes. In such cases, rheological effectiveness should be re-evaluated.
Yellowing risk: Under standard dosages, no negative effect on yellowing is observed. For sensitive systems or higher dosages, evaluation is recommended.
Reactive & catalytic systems: When used in systems containing cellulose nitrate, storage stability testing is advised.
PVC Resins
Properties & Benefits:
Anjeka-4410 is widely used in various PVC resin systems to:
Additional advantages in PVC systems:
-
Minimizes color bleeding in pigmented slurries
-
Controls coating set during baking
-
Increases stability of PVC foam during mechanical mixing
RECOMMENDED ADDITION LEVEL
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.
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.
