Description

Coapur™ XS 22 is a water-soluble non-ionic polyurethane thickener specifically designed for alkyd emulsion systems. Here are its typical characteristics and properties:

Nature: Water-soluble non-ionic polyurethane
Appearance: Viscous whitish liquid
Solid Content: 30%
Active Content: 25%
pH: 7
Brookfield viscosity: 5000 mPa.s
Specific gravity: 1.03
Neutralization type: Sodium
Solvent: Water

Description:
Coapur™ XS 22 is tailored for alkyd emulsion binders, which interact differently with fillers, pigments, and various hydrophobically modified additives compared to other water-based emulsion binders like acrylic, styrene acrylic, or ethylene vinyl acetate. Alkyd emulsions generally exhibit stronger reactivity, resulting in higher viscosities, particularly at low shear rates, and poorer storage stability. Coapur™ XS 22 addresses these requirements by providing specific thickening properties for alkyd emulsion systems.

Recommended Addition Level:
Half or a third of the total amount should be incorporated before adding pigments and fillers, with the rest added at the end of formulation. The typical dosage ranges from 0.5% to 2% (active on total formulation weight), depending on the desired high shear viscosity.

Standard Packaging:
Available in 1000L IBC and 220L drum. Other packaging options may be available upon request.

Handling & Storage:
Store between 5°C and 40°C, protected from weathering and direct sun exposure. Reseal packaging immediately after use. Use within 12 months under these conditions.

Health and Environmental Data:
Refer to the Safety Data Sheet for safe handling. For more information about health and environmental data, contact the manufacturer.
