Lanphos PS6-25A

Product Category: Anionics

Emulsifier for Emulsion Polymers

INCI Name: Ammonium Trideceth‑6 Phosphate

Quick Links

Lanphos PS6‑25A is a high‑performance anionic emulsifier specifically developed for emulsion polymerisation applications. As a powerful primary emulsifier, it can be used across a wide range of polymer systems without the need for a secondary stabilising surfactant, offering formulators a simple and effective route to highly stable latex systems.


The product is designed to produce extremely small polymer particle sizes while providing an in‑built stabilisation mechanism that helps prevent re‑agglomeration of polymer particles. This enhanced stabilisation contributes to excellent latex stability and improved shear resistance throughout the polymerisation process.


Lanphos PS6‑25A is suitable for use in a broad range of polymer chemistries, including styrene‑acrylic, vinyl acetate homopolymer, and pure acrylic systems. The product is APE‑free and VOC‑free, making it an attractive choice for modern emulsion polymerisation formulations where performance, stability, and regulatory compliance are key requirements.

Applications

 

Lanphos PS6‑25A is used in a wide range of emulsion polymerisation applications where excellent emulsification, particle size control, and latex stability are required, including:


Styrene‑Acrylic Polymers
– Produces sub‑micron particle sizes and excellent shear stability in styrene‑acrylic copolymer dispersions used in architectural coatings, adhesives, fillers, and glass fibre binders.


Vinyl Acetate Homopolymer (PVAc) Emulsions
– Suitable for the manufacture of PVAc emulsions used in wood glues, water‑based adhesives, carpet backings, paper coatings, and construction products.


Pure Acrylic Emulsions
– Provides effective emulsification and latex stabilisation in 100% acrylic systems used in decorative coatings, industrial coatings, building materials, and non‑woven fabrics.


Emulsion Polymerisation
– Functions as a powerful primary emulsifier that can be used without the need for a secondary stabilising surfactant, simplifying formulation design and improving process efficiency.


Latex Stabilisation
– Delivers built‑in emulsion stabilisation, helping to prevent polymer particle re‑agglomeration and providing excellent long‑term latex stability.


Coatings and Adhesives
– Suitable for polymer systems used in architectural coatings, industrial coatings, adhesives, sealants, and related applications requiring stable, high‑performance latex binders.
