UV/EB Protocol - Requirements Related to Occupational Health and Safety Stipulated Consistently in Europe

Environmental protection requirements but also advantages in the quality and processability have up to now lead to a rapid increase of EB/UV curing paint systems in the printing industry. New paint systems and customised process engineering will in the near future establish this technology in other areas of the coating industry. However European di

3D Lithography of Organo-Soluble Mold Materials for Sol-Gel Nanocompsites

Rapid Prototyping (RP) is a suitable, manufacturing method for fabricating structures with highgeometric complexity and heavily undercut features, which cannot easily be fabricated with traditional manufacturing 1 In Scheme I the direct light processing (DLP) based machine Perfactory® (Envisiontec) is shown. For fabrication of 3D parts the CAD mode

Radical Ketosulfone Derived Photoinitiators: Cleavage Process and Polymerization Activity

Photoinitiators based on a ketosulfone KS structure have been tested in radical photopolymerizationreactions for coating applications. Molecular modelling calculations help to describe the excited state properties. A discussion of the photochemical reactivity vs the practical efficiency in polymerization is presented.

Reach - Exposure Scenarois (Categories versus UNITECH Data)

Coatings and inks play an indispensable role in our modern world and cover many things we use. Whereas coatings and paints stand mainly for protection, printing inks for information and decoration and colours for expression. Although REACH (Registration, Evaluation and Authorization of wish to ensure that harmonised, accurate information is communi

Reactivity and Network Structure of UV- and EB-Cured Bis-Phenol A Ethoxy Diacrylate

Theradiation-induced polymerization of acrylates is known to proceed in a very heterogeneous manner and the resulting networks often display heterogeneities at various dimension scales. In particular, the early formation of microgels produces a heterogeneous structure including highly cross-linked particles together with a gelled network, with dang

Hydrogen Bonding and Rate Enhancement in Photoinduced Polymerization of Monofunctional Hydrogen Bonding Acrylates

The relationship between the rate of photopolymerization, degree of hydrogen bonding in acrylates and methacylates have been investigated. The rates of polymerization for hydrogen bonding of acrylates are significantly higher than those observed for typical monofunctional alkyl-acrylate monomers and comparable to multifunctional monomers. By

Photopolymerizable Biopolymers for Rapid Prototyping of Cellular Bone Replacement Materials

The, disadvantages of materials, which are currently used in orthopaèdic surgery have' led to the development of new synthetic biocompatible and biodegradable materials. Rapid 1 offers the possibility- to fabricate cellular structures with nearly. arbitrary form and structures . out of photocurable liquid acrylate-based formulations by radical poly

Use of a new Photoinitiator in Graphic Arts

The penetration of energy curing technology in graphic arts is still marginal, even if it has all the characteristics to become the technique of choice, mainly for high printing speed, increasing quality, reduced VOC release. In order to improve these characteristics and to satisfy unmet needs, a continuous improvement of the components of the form
