Right: Verimas- ter technology, from Addmas- ter UK, can be used in all polymers to

create a unique identifier signature

technology is unique and is not based on infrared or UV fluorescent taggants; he does not disclose precisely what it comprises, however. Verimaster from Addmaster (UK) is available in

masterbatch, liquid or powder forms, and is said to be suitable for use with plastics, as well as paper, textiles and coatings. According to Karl Shaw, Marketing Manager at the company, the Verimaster technology is used in a wide range of industries from high end fashion goods to car components. “Our additive can be identi- fied even at very low dosage levels, making the product itself the brand security tool,” he says. “Verimaster works in all polymer types, including engineering grades. It will not interfere with any colour, physical property or transparent finish of a product.” There are three standard detection methods for

Cenisio says. “Converters using the masterbatch will be audited regularly. We will make sure that nothing is lost along the production chain, even scrap is accounted for. We have to make sure all the material stays within the specified production process.”

Taggant reassurance Another masterbatch producer working on anti-coun- terfeit products is Teknor Apex. Earlier this year, its Teknor Color division introduced a series of colour masterbatches with what it says are “exceedingly small” traces of an anti-counterfeit marker (a taggant) that enables plastics manufacturers to ensure product safety, supply chain integrity, and brand reputation with no effect on colour quality or product performance. The company says that its DeTek colour master-

batches can be used at standard let-down ratios in a wide range of thermoplastics. “DeTek concentrates can also help provide assurance to automotive, electronic, medical device, and other OEMs that use components from multiple contractors for regulated or high-specifi- cation applications,” the company claims. The taggants contained in products with DeTek

masterbatches respond to detection equipment and are difficult for fraudulent manufacturers to identify or copy, Teknor Color says. As a service to customers, the company can carry out an analysis of suspect products to avoid the need to invest in analytical systems. John Wood, Technical Manager at Teknor Color, says

the Teknor Color permanent marking technology is easy to identify in-house or in the field without the require- ment of skilled analytical professionals or sophisticated test equipment. “Even in long term outdoor applica- tions, non-technical staff can determine if a part is genuine or not,” Wood says. “The time required would only be a few minutes at most.” He adds that the

Verimaster - visual, audible and lab testing. The visual detector is a pen-sized laser that causes the Verimaster additive to glow. The audible detection device is a proprietary detector similar in size to a key fob that emits a noise when the Verimaster additive is detected. Addmaster will create additives on a licensed basis, accessible only to the one customer. The detectors can be programmed to locate a single

additive, or up to one hundred different combinations of additives. Each signature can be made unique to the client or to an application. “The detection devices are completely controlled by Verimaster, so it is virtually impossible to replicate a specific signature to fool the device,” Addmaster says.

Extended options Microtrace, which has been involved in anti-counterfeit- ing taggant technologies for more than 30 years, recently expanded its offering to include phosphor and infrared taggant systems. “There continues to be a wide range of anti-counterfeit security options for plastic compounders, each having their own pros and cons and levels of security,” says a spokesperson for the company. “Microtrace offers a variety of proprietary taggant technologies to fit any project.” Microtrace Microtaggant Identification Particles, for

example, are microscopic opaque particles, which through a multi-coloured layered structure provide a unique code exclusive to each customer or application. They provide a quick and easy field identification with inexpensive devices, such as handheld UV lights or laser pens. The colour layered code can be read with a microscope. Microtrace Molecular Taggants provide yes/no

authentication as well as quantification to detect levels of dilution and mix ratios. Their advantage is that they can be incorporated into plastics at trace levels. On the
