The 4310-20X Anti-sinking and thickening thixotropic agent is a high-performance rheological additive specifically engineered for solvent-based coating systems. Formulated as a pre-activated polyam…
Superior Anti-Sinking: Effectively prevents the hard-packing of metallic pigments, glass beads, and heavy mineral extenders during long-term storage.
Excellent Sag Resistance: Enables the application of high-build coatings on vertical structures without compromising surface smoothness or uniformity.
Rapid Thixotropic Recovery: Immediate viscosity rebuild after application ensures optimal film thickness and prevents “edge pull” on complex geometries.
Temperature Stability: Maintains consistent rheological performance across varying processing temperatures without the risk of seeding or graininess.
Enhanced Flake Orientation: Facilitates the uniform alignment of metallic and pearlescent pigments, significantly improving the optical “flop” and metallic brilliance.
规格
技术亮点
Chemical Composition: A specialized pre-activated organic polyamide wax dispersion delivered in a precise hydrocarbon and alcohol solvent carrier system.
Active Content: Features a high concentration of thixotropic fibrils (20% ± 1%), ensuring potent rheology control at exceptionally low addition dosages.
Broad Compatibility: Demonstrates excellent solubility parameters with acrylics, alkyds, epoxies, chlorinated rubbers, and unsaturated polyester resin systems.
Zero-Heat Activation: Unlike traditional waxes, this grade is fully pre-activated and does not require specific temperature windows for effective dispersion.
Surface Integrity: Engineered to provide rheology control with negligible impact on intercoat adhesion or final surface gloss levels.
实际行业应用
应用领域
Marine and Protective Coatings: Essential for high-build anti-corrosive primers and antifouling paints requiring extreme vertical sag resistance in harsh environments.
Industrial Machinery Paints: Used in heavy-duty equipment finishes to prevent pigment sedimentation and ensure uniform color consistency across large batches.
Automotive Refinish: Optimizes metallic flake orientation in solvent-borne basecoats while providing critical viscosity control for high-solids clearcoat applications.
Wood Finishes: Improves the suspension of flatting agents and stains in polyurethane and acid-curing wood coatings for a more consistent finish.
Adhesives and Sealants: Acts as a primary thickening agent in solvent-based mastics to prevent slump during the curing process.
