New UV adhesive series, the crystal-clear solution for rational and safe bonding, even for special application such as a laminating adhesive to manufacture glass touch panels.
The headline -“Stencil Perfection & More” - aptly summarises the series of product innovations for stencil-making, adhesive bonding, resists and surface protection – all ofwhich KIWO had presented at the FESPA 2013.
Emulsions, the heart of the stencil, are the focus of the FESPA product presentation. With new developments specifically for high-end printing applications, KIWO is launching a number of new products, with properties which were previously unattainable.
KIWO is also showcasing the CLEANLINE series of advanced cleaning solutions for automated and manual cleaning systems.
Screenprintable adhesives are an important part of the KIWO range of products. Whether solvent, water or UV- based, KIWO has the right screenprintable adhesive for graphic and industrial applications. Amongst others, specialties include heat-activated adhesives and new conductive adhesives.
New at FESPA 2013:
These belong to the specialty programme KIWO is introducing for the first time at FESPA. A new and technically interesting field of development, which opens up many additional possibilities for screenprinters.

Thanks to further developments in quality, screenprintable pressure-sensitive adhesives have made their mark in many industrial applications. Which screenprintable pressure-sensitive adhesives are available on the market and where are their preferred areas of application?
For processing liquid adhesives, the screen printing method has established itself alongside the conventional systems like curtain coating, spraying, anilox and knife. The specific advantages of using the screenprinting method for processing adhesives was already recognised in the early 1970’s. Today pressure-sensitive adhesives, which have been printed on substrates can be found in many industrial areas of application, as for example, the automotive industry, household white goods and the electronic industry. More can be found in the production of optical displays as well as the advertising and sign making industry.

In the cleaning of a screenprinting stencil, a variety of chemicals are used which vaporise, are discharged into wastewater or are subject to expensive special waste disposal procedures. From an environmental and economic point of view, it is obviously desirable to reduce these polluting factors to a minimum.
Screen printers have several different technologies at their disposal, which will be presented here in detail with their respective advantages and disadvantages.
Dr. Roland Studenroth, KISSEL + WOLF GmbH
In the course of the 80s, a new technology from Japan edged its way into the screenprinting market. This was the technology of single-component emulsions based on SBQ. The abbreviation SBQ is derived from the product name "Stilbenium quarternized" and specifically means that a water-soluble, UV light-sensitive stilbene group is chemically bonded with the polyvinyl alcohol (PVA) contained in emulsions (see Figure 1), so that for light sensitizing a second component, such as diazo is no longer needed. Because of it being a single-component product, the SBQ emulsion technology first experienced a boom, but also contributed at the same time to the perfectioning of the alternative dual-cure diazo technology. Today both technologies are firmly established in the market and complement each other, i.e. there is dual-cure technology also found in SBQ-sensitized products and to achieve specific properties, SBQ emulsions can be additionally mixed with diazo compounds.
KISSEL + WOLF GmbH, market leading manufacturer of screenable adhesives, now offers KIWOPRINT UV 92, which is a new UV pressure-sensitive adhesive for decorative foils, front panels and visual instrument panels.
Due to its good tack properties, it is also suitable for labels and decals.
Typical applications include:
The adhesive’s fast curing is a special advantage giving short cycle times.
