Back to overview Permacol 2035Z-serie

The Permacol® 2035Z-series are smooth, thixotropic, one component adhesives on epoxy base for SMD/SMT purposes. Adhesives of the 2035Z-series can be applied, dispensed or screen printed, without stringing and will not sag whilst curing. These thixotropic adhesives hold electronic components in position and prevent movement due to vibration even before curing.

The cured adhesive has excellent electric properties and heat resistance during soldering.

In the 2035Z-series, we supply adhesives in different viscosities, adjusted to the method applied or type of electronic component to bond. This viscosity assigned by the extensions /15, /25, /30 and /40 are:

VISCOSITY TYPE MAIN APPLICATION
2035Z/15 Dispensable adhesive for larger components, High dispensing temperatures possible, Stencil printing.
2035Z/25 SMD-adhesive for stencil printing. High viscosity.
2035Z/30 SMD-adhesive for stencil printing / dispensing with high viscosity.
2035Z/40 SMD-adhesive for stencil printing / dispensing.

2035Z/15 2035Z/25 2035Z/30 2035Z/40
Wet strength 1.200 Pa 1.500 Pa 1.000 Pa 1.900 Pa
Viscosity at D=30/s 23°C  65 Pa.sec 80 Pa.sec 130 Pa.sec 90 Pa.sec

   

 

It must be clear that the curing time depends on several parameters. Oven capacity, board design, type of components on Printed Circuit Board, and type of Printed Circuit Board (multilayers have higher heat capacity) can influence the cure speed.

Permacol 2510

Permacol® 2510 A/B is a 2-component epoxy adhesive with excellent heat conductivity. This adhesive has been developed to be conductive to heat only and not to electrically. For example it is used as adhesion medium on heat sinks.

The 2510 is cold curing, therefore complete curing takes place at room temperature.
