Applications:

Mesitol® P LQ 50% is a versatile anionic dispersing and fixation agent used across several industrial sectors, particularly where resin control, pigment dispersion or dye fixation is required.  Typical applications include:

• Pigment dispersion – enhances the uniformity and intensity of inorganic and organic pigments

• Dyestuff production – used as a varnishing and fixation agent for basic (cationic) dyestuffs

• Paper manufacturing – prevents pitch agglomeration, reduces deposits, improves machine runnability, and levels dye uptake

• Cement and construction materials – functions as a dispersant in mineral systems

• General industrial use – dispersing agent in systems requiring improved stability and homogeneity

Description:

Mesitol® P LQ 50% is an anionic dispersant produced via condensation of formaldehyde and naphthalenesulfonic acids. It offers excellent dispersing efficiency, pitch control capability, and dye-fixation properties. In papermaking, it suppresses pitch agglomeration, preventing deposits, holes, and runnability issues. Its strong dispersing power makes it effective for pigment preparations and improving color uniformity.

In acid conditions (pH < 5.5), Mesitol® P LQ 50% also acts as a fixation agent for basic dyestuffs, enhancing dye uptake and improving fastness. The product can be incorporated in a wide range of aqueous industrial formulations.

Note: The product has been stored for more than 10 years, well past its nominal shelf-life. No warranty or liability can be provided regarding stability, performance, or suitability. Material is offered strictly as-is.

Reason for Sale: The product remained unused after production was discontinued due to lack of market demand for this type of dispersant. The remaining inventory is being liquidated.

Key Features:

• High-performance anionic dispersant

• Effective pitch control agent for pulp and paper

• Improves dye uniformity and fixation

• Enhances pigment dispersion and stability

• Suitable for use in cement and construction materials

• Compatible with a wide range of aqueous systems
