LIOPUR PFL 1154

LIOPUR PFL 1154 is described as an aqueous, aliphatic polyurethane dispersion based on a combination of polyester and polycarbonate.

Supplied Form: It is supplied as a 35% solution in water.

Properties:

• Appearance: Transparent to slightly colloidal.
• Non-volatile content: 35 +/- 2%.
• pH-value: 7.0 - 8.5.
• Viscosity: 20 - 500 mPas.
• Minimum film forming temperature: Approximately 20°C.
• Organic solvents: Less than 1%.

Properties and Fields of Use:

• LIOPUR PFL 1154 forms transparent films that are tack-free and exhibit good surface hardness after air-drying.
• It is characterized by high toughness, resilience, and tear strength.
• It has high abrasion resistance and excellent chemical resistance, making it suitable for use in combination with water-emulsifiable polyisocyanates for air-drying, aqueous, 2-pack parquet floor varnishes.
• It enhances the wood grain for water-thinnable formulations.
• It contains NCO-reactive groups, allowing for a binder/hardener ratio of 100:10 based on applicational tests.
• It can be used in DIY applications due to its simple manual incorporation of the hardener component into the base paint in two-pack formulations.

Storage: The dispersion should be stored in tightly sealed containers in a frost-free place and contains preservatives.

In summary, LIOPUR PFL 1154 is a polyurethane dispersion primarily used for coating applications, particularly for producing transparent films with various desirable properties such as hardness, toughness, resilience, and abrasion resistance.
