I. Basic Information

• Product Type: Dispersant
• Brand & Model: Disponer 904S
• Packaging Specification: 25 kg/barrel, featuring a sealed packaging design for easy storage and transportation, suitable for industrial bulk use scenarios.
• Core Composition: A mixture of high-molecular-weight dispersant and modified silicone resin, formulated into a silicon-containing special formula system through scientific proportioning.

II. Key Features

1. Efficient Pigment Dispersion and StabilizationAs a silicon-containing special wetting dispersant, its high-molecular-weight dispersant component can quickly penetrate the surface of pigment particles such as titanium dioxide, reducing interparticle agglomeration force to achieve uniform dispersion. This fundamentally prevents floating color (uneven color caused by stratification of different pigments due to density differences) and blooming (local color shade variations), ensuring consistent color in coatings or inks. Meanwhile, the modified silicone resin forms a protective film on pigment surfaces, effectively preventing particles from re-aggregating, avoiding sedimentation and hardening during product storage or use, extending shelf life, and ensuring application stability.

2. Broad CompatibilityIt exhibits excellent compatibility with medium-to-high polar solvent-based systems, solvent-free systems, and various resins (alcohol/amino resins, polyester/amino resins, acrylic/amino resins, etc.). Its addition does not affect key properties such as gloss and adhesion of the system, making it suitable for scenarios with high requirements for the appearance and performance of finished products.

3. Enhanced Application and Product QualityA uniformly dispersed system improves fluidity and leveling, reducing application defects such as brush marks and orange peel. It also lowers system viscosity, facilitating mixing, transportation, and application operations, indirectly enhancing production efficiency.

III. Application Fields

• Coating Systems: Ready-mixed paints, two-component polyurethane coatings, epoxy coatings, eco-friendly coatings (e.g., low-VOC coatings), baking paints (automotive paints, industrial baking paints, etc.), especially suitable for decorative or protective coatings requiring high color uniformity.
• Resin Systems: Compatible with alcohol/amino, polyester/amino, acrylic/amino resin systems, without interfering with cross-linking reactions, ensuring stable performance of resin products.
• Ink Systems: Screen printing inks (e.g., packaging printing, PCB screen printing, etc.), ensuring printed patterns have full color and clear edges.
• Other Scenarios: Medium-to-high polar solvent-based and solvent-free systems (e.g., adhesives, sealants), effectively solving pigment dispersion challenges.

IV. Usage Recommendations

1. Addition Timing: It is recommended to add during the grinding stage or paint/ink mixing stage. The timing can be flexibly adjusted according to the production process to ensure full contact between the dispersant and pigments.
2. Dosage: Adjust based on pigment type and content. It is generally recommended to determine the optimal ratio through small-scale tests, with a typical dosage of 0.5%–2% of the pigment weight. After addition, stir under appropriate shear conditions to ensure uniform mixing.

V. Storage & Shelf Life

• Storage Conditions: Store in a cool, dry, and well-ventilated warehouse, avoiding direct sunlight and rain. The recommended storage temperature is 5°C–35°C.
• Shelf Life: Under proper storage conditions, the unopened product has a shelf life of 12 months. Once opened, seal tightly and use as soon as possible.
