Dartek Cast Nylon Film

Description

[DuPont (Canada)] A registered trademark for a thermoplastic, nylon film composed of Nylon 6,6. Dartek is a clear, strong film with low permeability and resistance to abrasion, oil, chemicals, and vapors. The soft, transparent, stretchable film will conform to any shape using vacuum or gentle heating, such as with a hair dryer. Dartek is sold for use as a covering membrane for lining paintings on a vacuum table (Conservation Support Systems, 1998) and is marketed by its manufacturer for wrapping, handling, transporting and storing paintings and fine art. The tear resistant film has low oxygen and moisture permeability and can easily be adhered to other surfaces or itself with heat, hot melt or double sided tape. Dartek is used in industry for lamination and packaging.

Handling and Workability

The tear resistant film has a 'saran-wrap' feel and clarity that is softer and more pliable than Mylar or glassine. Moisture and heat should be avoided as is may cause the film to stick. (PACCIN). In dry environments, the films can be brittle. Dartek C-917 can be treated on both sides for ink, adhesive and coating receptivity.

Forms and Sizes

Available in rolls from 10” to 88” wide and in gauges from .0075" (.19 mil) to 0.75” (1.9 mil).

Applications for Storage Exhibit and Transport

  • Dust cover where light sensitivity is not an issue
  • Replacement for glassine when wrapping paintings susceptible to tackiness or abrasion
