Conventional silicone release coatings have been, to date,thermally cured. The performance. and production techniquesassociated with thermal curing are well known ' and welladvanced into high speed production. There are, however, somedisadvantages associated with thermal curing and this is thearea we wish to address with our radiation curable silic

INTRODUCTIONThis paper will describe the equipment and process currently used and how a relatively new and extremely versatile and compact high irradiance light source can totally eliminate the low intensity light tunnel and significantly reduce operating costs.

INTRODUCFIONThis paper reviews some recent developments in EEC chemicals control legislation governingdangerous chemicals, dangerous preparations, and food contact' 'materials.' After briefly'reviewing the content of the legislation, it will attempt to highlight changes from previouslegislation, cost implications for industry; and anomalies or grey

However, asearch of the patent literature shows (ref. 3) that many-attempts have been madeto develop melamine acrylates and perusal. of product data sheets from the 1970's and early 1980's reveals that several products had been introduced to the market (ref. 4) . However( to the best of our.knowledge, noneof these products has survived to this day.

1. INTRODUCTIONWeb-offset printing has shown strong growth in recent years because itimproves the competitive positions of both folding-carton and flexible-packagingconverters. For the carton printer, instead of four separate, low-speed operationsfrom roll to finished carton (sheeting, printing, die-cutting and stripping), theyare choosing higher s

Raw materials'for lithographic offset printing must meet, apartfrom viscosity and rheology,a number of requirémeñts related tothe printing process. The process is based on a chemicaldifference between image and non image areas (in contrast toprinting 'systems with a physical 'relief differentiation). Toobtain an the lithographic ink is in competiti

IntroductionLightwave data transfer based on fibre optics is an almost mature technology, which enabled an increasing effiency of telecommunicationwithin last decade. As thetechnology grows in use so does the demandfor reliability and economical fibre productionContrary to LAN's and related applications — where fibres are embeddedin a polymer matri

1.Introduction.Photosensitive polymer coatings for imaging applications haveachieved a high levelof performance at the end of this century.Since their introduction in 1957 as relief printing plate anda few years later,in other important fields of the graphicarts,their market share has been characterized bya constantgrowth rate.Simultaneously photor
