Conductive Coating

Clear, best all round performer.
Our new clear coating has been under test for over 2 years and is now available for sale. This material does not rely on ambient humidity to make it conductive and is stable in dry or humid conditions. Exceptionally thin film coating adds negligible mass to the diaphragm. Can be diluted to produce desired surface resistance. 25ml of concentrate will make 100ml of usable coating. Typical coverage is 1ml per 900 sq cm (1 square foot)

Adhesives

Why mess with 2 pack epoxies? We have the answer to bonding diaphragms quickly and reliably to the air gap spacers
.

Polyurethane,
very strong bond in shear and peel. Slow curing gives time to get things exactly right.  Can also be used to damp stators to prevent ringing.

100ml

Cyanoacrylate + Primer,
bonds diaphragms to spacers instantly.
Excellent for achieving fast results.
Primer is brushed onto the film where the adhesive will contact it

Copper EHT Foil


It is essential to provide an EHT rail around the perimeter of the diaphragm. This is best applied to the surface of the air gap spacer that comes into contact with the conductive coating. Our foil is 4 and 6mm wide, 25 microns thick, self-adhesive and can be soldered.
