CARBODILITE™C-218

  • Compliant with VOC regulations

    Water crosslinking agent carbodiimide

    C-218

    carbodiimide C-218 is a new product in the carbodiimide series with high crosslinking and economy. Whether the substrate is hard or soft, it can be applied to improve various performance aspects.

  • Use

    Surface coating of synthetic leather,fhlm surface coating,paint,letterpress printing,glue,

    Textiles(surface coating, printing and dyeing) etc.

  • What is CARBODILITE?

    Waterbone polycarbodiimide resin which contains carbodiimide [-N=C=N] group with hydrophilic segments

    Very safe for use and environment friendly crosslinker Applicable for VOC regulatory compliance products

    Wide range of products(Customers can choose the most suitable ones)

  • Features

    Economical

    · Drug resistance: (MEK resistance) test
    · Test: When added to acrylic lotion for coating, the drying temperature and time are 80℃×10min
    · Due to the affordable price of the product, we can increase the dosage to enhance its performance.

  • High Polymer

    · Drug resistance: (oleic acid resistance) test
    · Test: When added to waterborne polyurethane resin for leather, the drying temperature and time are 130℃ for 5 minutes.
    · Test method: Apply oleic acid-containing absorbent cotton to the coating film (out of 35 points)

  • Others

    Others:Long pot-life,non-yellowing

    · High storage stability, no yellowing, longer usable time compared to isocyanates, no excess by-products during reaction, and no carbon dioxide produced.
    · Due to its good dispersibility, no preliminary dilution is required.
    · Usable time: Viscosity test (when added to waterborne polyurethane resin) Storage Conditions 50℃ Test method. TVB-10 Type viscosity meter Measured at 25℃

    Reaction mechanism

    • The carbodiimide group can react with carboxylic acid at room temperature.
      Carbodiimide achieves a longer pot life through the following mechanism.

    Usage direction
    • 01

      Suggested dosage level

      The ratio of CARBODILITE solid content to resin solid content is approximately 3-7%

    • 02

      For faster reaction

      Increase curing temperature

    • 03

      For extending pot-life

      Increase pH with neutralizer (ammonia, amine etc.)
