ENVIRONMENTAL PROTECTION BY EMISSION-FREE LACQUERING, PRINTING AND GLUING

The pollution of the air with volatile organic compounds is growing to an alarming extent. In order to protect our environment in the future, it is essential to reduce ecological damages. Tightening environmental regulation force the users of lacquers, printing inks and adhesives containing solvents, to look for environmentally harmless processes. The aim is to emit considerably less solvent or cracked harmful products into the atmosphere than previously, and improved quality standard.

The solventfree converting system will be required for the future.

 

EB – THE SOLVENT-FREE, NON-THERMAL HIGH-TECH CONVERTING

EB is the abbreviation for a new environmentally safe, heat and solventfree technique: Electron-Beam curing.

The advantages of this technique:

	Environmentally friendly due to a 100 % solid system. EB works absolutely without emissions.
	No substrate heating.
	Substantial production increase compared with conventional heat-treatment methods and UV-technology, also with pigmented layers.
	Immediate further treatment of converted products without postcuring.
	Low space requirement. Integration into existing production processes without any problems.
	Exact repeatability of production conditions is obtained due to high dose accuracy. There is also no wastage when starting up and shutting down the plant.

 

IN THE WOOD TECHNOLOGY, METAL AND PLASTIC PROCESSING

In the surface converting of solid materials the EB-technology has already been used successfully in the following operating fields:

	Curing of top lacquer on doors Curing of top lacquer on furniture front parts
	Curing of the coating on raw boards in the wood industry
	Curing of coatings on three-dimensional parts, e.g. rims and pump housings on plastic or metal
	Curing of coated edges and panels in the wood and laminate industry All-around curing of coated profiles in one step
	Curing of the coating on architectural claddings for outside applications Curing of the coating on wood-cement boards for outside and inside application
	Curing of coatings on MDF boards (Medium-Density-Fibre-board) Curing of bonded composite materials
	Curing of impregnation and top lacquer on laminated boards
	Curing of impregnation and top lacquer on flooring materials

 

IN THE ADHESIVE-TAPE TECHNOLOGY, PAPER CONVERTING AND PRINTING INDUSTRY

In the surface converting of flexible materials the EB-technology has already been used success-fully in the following operating fields:

 

	Curing of release coatings Crosslinking of films and foils Production of films out of the liquid phase
	Crosslinking of thin insulation of wires Crosslinking of jackets for cables
	Post-vulcanisation of O-rings and sealing elements for improvement of friction Sterilization / decontamination Stabilisation of rubber raw materials by partial vulcanisation
	Vulcanisation or crosslinking of pressure-sensitive adhesives Post-crosslinking of binding agents of magnetic materials
	Curing of high-gloss lacquering of special paper (e.g. photographic paper) Curing of web offset printing inks, perhaps finishing varnishes Curing of intaglio prints
	Crosslinking of flock adhesives Crosslinking of laminating adhesives Colouring of textiles Production of antistatic finish Curing of metal coating from roll to roll (coil coating)
	Metallizing of paper, e.g. curing of basic lacquer and adhesives for selective or plane transfer metallizing as well as curing of overpaints Curing of labels

The surface treated with EB-technology is

	free of harmful substances
	non-ageing
	weather-resistant
	scratch-proof
	colour-fast
	resistant to organic solvents
	resistant to a wide range of chemicals.
