Efficient Low to Medium Shear Thickening | Technical Control Polyurethane Associative Thickener

The thickener serves as a crucial rheological additive, enhancing the viscosity of coatings, textile adhesives, and facilitating smooth ink transfer while preventing drips during application. It not only improves mechanical properties but also ensures long-term storage stability. This additive is vital for both low-viscosity water-based inks and coatings, as well as high-viscosity textile adhesives.

The market offers a diverse range of thickeners, which can be broadly classified into four categories: inorganic thickeners, cellulose-based thickeners, polyacrylate thickeners, and polyurethane associative thickeners. Each category exhibits distinct performance characteristics. In water-based systems, the demands on thickeners are particularly rigorous, requiring a balance of efficient thickening, excellent flow properties, and stable long-term performance.

Technical Control’s Low to Medium Shear Polyurethane Associative Thickener

The polyurethane associative thickener developed by Technical Control demonstrates exceptional compatibility with a wide range of water-based resin systems. This product line not only delivers high thickening efficiency at low to medium shear but is also APEO-free, ensuring a favorable balance between thickening effectiveness, flow characteristics, and gloss retention. As a result, it effectively meets the diverse requirements of various coating formulation designs.

Product Features

Stable System
Provides excellent thickening effects, along with a balance of leveling and gloss.

Broad Compatibility
Demonstrates excellent compatibility with both ionic and non-ionic emulsions, without affecting the water resistance of the film.

Excellent Leveling
Features outstanding leveling performance and certain anti-sag properties, ensuring good screen passing for textile adhesives.

Good Film Formation
Delivers exceptional coverage with uniform and full film thickness, without compromising the original gloss of the coating.

Environmentally Friendly and Safe
Free from APEO components.

Application Areas

Various industrial coatings, including printing inks, shoe material thick pastes, leather finishes, and water-based adhesives.

Applications

The thickening capability of this product line is influenced by the emulsion’s structure, particle size, and the types of emulsifiers, as well as the film-forming agents and surfactants used in the coating.

This thickener can be incorporated during the grinding and tinting stages, with a recommended dosage ranging from 0.5% to 2% of the total formulation. The precise amount should be tailored to meet the specific formulation and viscosity requirements.
