Intertronics has released Polytec PU 1000, an electrically conductive polyurethane adhesive designed for applications such as die attachment and the bonding of components in hybrid circuits and surface-mount technology.

Polytec PU 1000 is a single-component, silver-filled paste adhesive that can be cured quickly at room temperature and is flexible and elastic. It is particularly suitable for the bonding of flex circuits, temperature-sensitive substrates or substrates with highly dissimilar coefficients of thermal expansion. It has found applications in smart cards and RFID circuitry, where cure can be effected in seconds.

According to the company, the adhesive is considered suitable for the electrical interconnection of active and passive components, particularly if convenient processing or high flexibility of the adhesive is desirable. This PU dispersion is suggested 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.
