In addition to Primarc’s extensive range of electrode lamps, Primarc have developed the electrodeless microwave
bulb, for use in industries such as fibre optic coating, electronics, compact disc and DVD manufacture, plastic container decorating, liquid finishing, two piece can manufacture, graphic arts and general
industrial applications.
The standard bulb has a mercury/gas fill, however, as with Primarc electrode lamps the spectral distribution can be
modified by the addition of special metal halides.
Metal halide lamps are mercury vapour lamps with metal halide additives which create specific wavelengths of
ultraviolet radiation to precision- match the photo-initiator being cured. The addition of metal halides creates a shift in the spectral output of a standard lamp, producing longer wavelengths. These
longer wavelengths enable a greater depth of cure to be achieved, making them particularly useful in the curing of pigmented and thicker coatings.
Primarc electrodeless microwave bulbs are manufactured from high-clarity, vitreous silica, normally referred to as
quartz. Quartz has the property of high-transparency to ultraviolet light, particularly at the shortwave end of the spectrum where over 90% of the UV energy generated is transmitted through the quartz.
The Primarc Quality Standard ensures that each lamp is not only manufactured to the most stringent of specifications,
but also lamp performance is consistent each time, every time.
Established in 1970, Primarc UV Technology is one of the world’s longest serving manufacturers of UV curing
lamps. During this time, our technical expertise, manufacturing processes and repeatability of lamp performance have reached a standard that has become the benchmark across the globe.
Since 1970 Primarc has played a leading role in UV lamp development. We are dedicated to providing design and
manufacturing support to end-users and original equipment manufacturers worldwide. Our R&D department works constantly with a range of companies to develop new applications for UV curing and improve
existing products.
