Product for Sale: Scientific testing coupon. 1 cm x 1cm Size 304 stainless with nanometer deposits of nano-silver. Average size of nanosilver particles in the coatingis about 50-100 nm. Full surface coverage. Substrate stainless steel coupon is about 1″ x 1″ and about 1 mm thick. Coating thickness is ~250nm nominal with range and topography of ~100nmm variations. The coating will contain an amount of silver that will be in the milligram range (about 100-200mg only). This product is not jewellery but only for science lab testing purposes. Only one coupon per order. *
Use of Product: Sample to test possible efficacy for antimicrobial permament (durable)- nano silver on a support substrate of stainles steel.
The particles are firmly attached but may also wipe under abrasive conditions depending on the force (an typical scratch test result is shown). Porosity will be present.
Variations are possible from coupon to coupon. Silver is two nines pure only and may be minorly oxidized. Natural oxidation of surface is possible, product is shipped in air atmosphere. Patented deposition process.
Product (the nano layered coating) expected to contain welded silver nano-particles (particles are welded to stainless surface and to each other). Coating may contain porosity – other elements like nitrogen and oxygen may be present in minor amounts. Not all phases will have been identified for nano size coatings.
