SILVERbac is a patented antimicrobial ingredient based on pure metallic silver that can be incorporated into a variety of substrates to confer durable antimicrobial functionality. It is not a coating or a topical treatment, and is not ‘nano-silver’

Improving your product with antimicrobial protection adds value, confidence and performance, and promises hygienic protection for your customers. SILVERbac is the obvious choice for performance, durability and for the wide range of germs it combats, including viruses and bacteria.

SILVERbac releases silver ions even when dry which disrupt metabolic processes across organism cell walls, ultimately leading to the demise of bacteria and other organisms. Learn more on our Technology page. 

No – once SILVERbac is incorporated, it will never wash out and provides antimicrobial protection for the lifetime of the product.

You can say that the article is protected by SILVERbac antimicrobial additive and support the claim with laboratory tests to internationally recognised standards. Our team can help with marketing claims.

Yes – tests prove SILVERbac confers rapid antiviral activity, but claims must be limited to the article as sold and supported by test data – our team can advise on the correct path to market.

Because unlike any other antimicrobial additive, SILVERbac will never wash out and is resistant to bleaches and detergents. SILVERbac treated fibres can be dyed without losing effectiveness, even Polyester.

SILVERbac can be incorporated into most polymeric systems, including fibres such as Polyester, Polypropylene, Nylon, Acrylic, and blends of those fibres with cotton, viscose, etc. Also, SILVERbac can be used to protect plastics such as PE, PP, ABS, etc.

SILVERbac can be used in textiles, plastics, polymers, paints and coatings. Examples of end uses include clothing, bedlinen, pillows, fiber-filling, upholstery, towelling, medical devices, coatings, carpets – the list is endless!

Incorporation of SILVERbac reduces the proliferation of bacteria such as MRSA, E-Coli, and has shown effectiveness against viruses as well as fungal contamination.

SILVERbac is made from food-grade silver and is non-toxic. We hold numerous international accreditations and hold IAC (International Antimicrobial Council) certification.

No – you cannot see or feel SILVERbac but it’s always there providing inherent antimicrobial protection.

A simple detector will confirm the presence of SILVERbac on any treated article, giving you and your customers confidence that your product is protected.

SILVERbac is registered with the EPA in the USA and is listed as an OEKO-TEX accepted ACP (Active Chemical Product).

In addition, SILVERbac is IAC (International Antimicrobial Council USA) Accredited & Certified, Bio compatibility tested, and has been tested for next-to-skin irritation.

Not as much as you might think, because the amount added is low compared to other antimicrobial treatments.

Unlike other antimicrobials, including silver-based additives, SILVERbac can’t be removed from a treated article, and so will not end up in waterways and oceans. Treated products last longer and are less of a drain on natural resources, and textiles treated with SILVERbac can be washed at lower temperatures, saving on energy resources and costs.
