Resists & coatings showcasing at Glasstec 2014 - for functional and decorative glass design

We offer our customers resists & coatings for functional and decorative glass design with application-oriented solutions.

 

These include heat-curable etching and plating resists for use in acidic and alkaline etching and plating baths for sharp contoured screen printing of glass or mono- and polycrystalline solar wafers; or peel and water-resistant, screenprintable masks with good resistance to aqueous cleaning processes, as they are commonly used in the pre-cleaning stage prior to glass processing. KIWO offers a wide variety of product solutions.

 

As an innovative product, KIWOMASK W 140 is particularly noteworthy, for this can be easily removed without the use of chemicals after the finishing process.

Glass adhesives showcasing at Glasstec 2014 - for durable and crystal-clear bonding

A very good capillary action, which is advantageous for glass lamination and edge-bonding, is best achieved with low-viscosity adhesives. High viscosities allow selective application of the adhesive.

 

The bond strength of the different grades was tested on different materials. In addition to high tensile shear strengths when bonding glass to glass and various metals, secure bonding of plastics such as ABS, polyamide or PMMA is also possible.

 

Coloured UV glass adhesives are available in addition to the colourless versions. This provides the user with a wider variety of applications without losing bond strength, transparency and UV stability.

KIWOPRINT UV 92 - UV-curable pressure-sensitive adhesive for technical applications

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:

  • Visual instrument panels for the automotive and electronic fields
  • Decals for bicycle and vehicle decoration
  • Labels and stickers for indoor and outdoor use

The adhesive’s fast curing is a special advantage giving short cycle times.

SBQ-based Screenprinting Emulsion Technology

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.
