Product Name: Dispersant MF

Chemical Name: Methylnaphthalene Sulfonate Formaldehyde Condensate

Primary Applications: High-temperature textile dye dispersant, concrete superplasticizer, and pigment stabilizer.

1. Product Overview

Dispersant MF is a premium-grade anionic surfactant engineered for extreme industrial environments. At its core, it is a highly refined methylnaphthalene sulfonate formaldehyde condensate that excels at breaking up particle agglomeration in liquids.

Whether you are trying to keep disperse dyes stable in a 130°C pressure vat or aiming to drastically reduce the water content in a high-strength concrete mix, Dispersant MF acts as a heavy-duty chemical referee. It attaches a negative charge to individual particles (like dye molecules or cement grains), forcing them to repel one another and remain evenly suspended. It is fully soluble in water—even hard, acidic, or alkaline water—making it incredibly versatile across different manufacturing sectors.

3. Key Industrial Benefits

Dispersant MF is a multi-industry workhorse. Here is how it performs in its primary applications:

For Textiles & Dyeing:

• Flawless Leveling: It prevents vat, reactive, and disperse dyes from clumping together in the dye bath. This completely eliminates the risk of color spots, streaking, or weak color yields on the final fabric.
• Extreme Heat Resistance: Unlike standard dispersants that break down under thermal stress, Dispersant MF maintains full particle suspension even in the aggressive, high-temperature (130°C+) environments required for dyeing synthetic fibers like polyester.

For Construction (Concrete & Mortar):

• High-Range Water Reduction: Acting as a potent superplasticizer, it allows ready-mix concrete producers to cut water usage by up to 15% without sacrificing flowability.
• Early Strength Gains: Lowering the water-to-cement ratio directly translates to denser, significantly stronger cured concrete, accelerating the timeline for large-scale construction projects.

For Pigments & Inks:

• Viscosity Control: When milling inorganic pigments (like titanium dioxide or iron oxide), adding this dispersant lowers the fluid thickness, speeding up the grinding process and ensuring long-term shelf stability without sediment settling.

4. Recommended Dosage & Application

Because of its high purity and ultra-low insoluble matter (under 0.05%), Dispersant MF mixes cleanly and requires relatively low dosing.

• Textile Dye Baths: For standard disperse or vat dyeing, add 0.5 to 1.5 g/L to the dye bath. For color-fixing or original padding baths, higher concentrations of 2 to 5 g/L may be required.
• Concrete Mixes: Typically dosed at 0.5% to 2.0% by weight of the total cementitious material. It is best dissolved in the mix water prior to being added to the dry aggregates.
• Pigment Grinding: Add directly to the mill alongside the raw dye or pigment powder to reduce mechanical grinding time and improve color strength.

5. Packaging & Storage

• Standard packaging is supplied in 25 kg woven bags with a robust, moisture-proof inner plastic liner.
• The powder is highly hygroscopic (it will actively pull moisture from the air). It must be stored in a dry, ambient warehouse. Ensure bags are hermetically sealed after opening to prevent the powder from caking into hard lumps.
