Super Dispersant LD-1652

(Similar to BYK-163)

First, summary

Ld-1652 is a high molecular super dispersant containing multiple anchoring groups. It has wide universality in various systems. It has excellent wetting and dispersion ability for various organic pigments, especially carbon black. It has excellent viscosity reduction, stability and color phase strength for carbon black. It can greatly reduce the operating viscosity of grinding system, increase the pigment filling amount, and has strong ability to prevent flocculation from coarsening, It can greatly improve the storage stability of color paste.

 

Second, physical and chemical data

Composition: high molecular polyurethane block copolymer containing pigment affinity group

Appearance: light yellow liquid

Active fraction: 45%

Solvent: propylene glycol methyl ether acetate / butyl acetate mixed solvent / xylene

 

Third, characteristic

It is suitable for medium and high polarity systems, has good matching with common coating resins, and has good universality in coating systems.

It can significantly improve the wetting and dispersion performance of the base material to the pigment, reduce the system viscosity, improve the fluidity, shorten the grinding and dispersion time, and has excellent ability to prevent coarsening. Compared with the small molecular wetting dispersant, it can greatly improve the storage stability of the color paste. It is suitable for all kinds of industrial coatings, anti-corrosion coatings, motorcycle coatings, etc.

 

Fourth, Application system and dosage

It is suitable for medium and high polarity systems. The addition amount is different according to different systems, 8% - 15% for inorganic pigments, 30% - 85% for organic pigments and 60% - 120% for carbon black (depending on the specific surface area of pigments).

 

Fifth, usage method

1. Add the dispersing agent into the base material and mix well, and then add pigment and filler for dispersion. It is suitable for any dispersion methods such as sand grinding, roller grinding, ball milling, etc.

2. High pigment carbon black, acetylene carbon black and high-grade organic dyes need to be pre soaked. The dispersant ld-1652 can be dissolved in the treatment solution, then added with pigment, stirred at high speed for 30-40 minutes, placed for 12 hours, and ground to the required fineness. The effect is particularly good.

Sixth, packing

25kg or 50kg iron drum / plastic drum

Keep away from heat and fire sources, store in a ventilated and cool environment at 0-40 ℃ and keep sealed.
