IMPRANIL® C SOLUTION

Impranil® C Solution is a polyester urethane adduct based on toluene diisocyanate, designed to be crosslinked with a polyisocyanate before use. Here's a breakdown of its characteristics and applications:

Characterization: Impranil® C Solution is a polyester urethane adduct based on toluene diisocyanate, requiring crosslinking with a polyisocyanate before application. It's suitable for formulating coatings with a medium-hard handle for various textile applications.

Form Supplied: It is supplied as a 30% solution in ethyl acetate.

Specification:

• • Viscosity: 27,000 - 53,000 mPa·s at 23°C
  • Non-volatile content: 30 ± 1%

Special Properties:

• • Good adhesion
  • Resistance to hydrolysis
  • Good weather stability
  • High abrasion resistance
  • Resistance to dry cleaning

Film Properties:

• • 100% modulus: 4 MPa
  • Tensile strength: 45 MPa (original)
  • Elongation at break: 400%
  • Lightfastness: 4

Applications: Impranil® C coatings can be applied by direct and transfer coating processes. The addition of specific crosslinkers and catalysts is necessary to achieve the desired properties.

Storage: It should be stored in the original sealed Covestro container at room temperature (20°C) and protected from moisture, heat, and foreign material. Proper sealing of containers is essential to prevent solvent evaporation.

Impranil® C Solution offers a range of desirable properties for textile coatings, providing medium-hard coatings with excellent durability and resistance to environmental factors.
