Polytec PT adhesives selector guide - .PDF file.

Polytec PU 1000 is a single-part adhesive from Intertronics that cures quickly at room temperature to a flexible, electrically conductive polymer. It can replace traditional epoxies that are rigid and require thermal processing, giving production efficiencies and enabling new applications where pliability and conductivity are important.

Polytec PU 1000 is an electrically conductive polyurethane that addresses applications in die attach, bonding of components in hybrid circuit applications and surface-mount technology (SMT) — areas where silver-filled electrically conductive adhesives have been used for many decades.

Usually such adhesives are epoxy-based, two-component or premixed and frozen single-component systems, but now the Polytec PU 1000 polyurethane option provides a flexible bond and cost-saving and performance advantages in the production process when compared with a standard two-part conductive epoxy adhesive.

Polytec PU 1000 has found applications in smart cards and RFID circuitry, where cure can be effected in seconds. It may be suitable for use in wearable technology — clothing and accessories incorporating computer and advanced electronic technologies. It is also suitable for electrically conductive bonding and coating applications on absorbing substrates such as fabric, paper, leather and cork and non-absorbing substrates including glass, ceramics, PMMA, metals and most plastics.

Key benefits

  • Polytec PU 1000 offers the simplicity of one-part application without mixing and an indefinite pot life with rapid cure at room temperature, for example 10 minutes at 23°C compared with 15 minutes at 120°C for a typical two-part epoxy.
  • The adhesive can be both stored at room temperature and can be cured quickly at room temperature. It is flexible and elastic, which makes it ideal for the bonding of flex circuits, temperature-sensitive substrates or substrates with dissimilar coefficients of thermal expansion.
  • Performance of the adhesive is considered excellent for the electrical contact of both active and passive components, especially when coupled with its ease of processing and high flexibility.
  • The adhesive can be dispensed automatically or applied manually and has rheological properties that make it particularly suitable for the requirements of the jet-type dispensers.
