Silicone UV-cure hardcoat technology: A tunable protective coating for plastics

This presentation shows how the use of silicone based UV curing monomers is helpful to propose monocomponent primer-free protective coatings for plastic substrates. Thus, the importance of deep understanding the behaviour of these specific monomers in a formulation in order to reach different properties is stressed out. The balance b

Silica nano particle composites in optically high transparent hybrid UV-curable formulations

This paper explains two different mechanisms of UV-curing: free radical curing and cationic curing.

Relating the Mechanical Properties of UV-cured Coatings to the Molecular Network - A new Approach to predict the Cross-Linking of Coatings

A new approach to simulate the cross-linking reaction of UV-cured coatings and to generate realistic atomistic model structures in dependence of the formulation and the ambient conditions has been developed. With these models, the mechanical properties of UV-cured coatings can be related to the molecular network. At first, an extensi

Real 3D Writing by Two Photon Induced Polymerization

Photo induced polymerization is utilized in stereolithography and rapid prototyping to provide 3D structures with greatly improved resolution in comparison to melt based 3D printing. Traditional stereolithography tends to be limited, however, to the diffraction limit of the light used. Achieving even smaller features is possible, and

REACH: review of past activities and outlook until 2013

Items included in this paper: Brief introduction to REACH & CLP2010 submitted dossiers : the story isn’t yet ending …2013 : the next deadline is coming soon!2015 : the challenge for DU’sREACH is still a business issue

Radiometry, how to compare different light sources

Nowadays, in the quality control of UV coatings usually broadband radiometers are applied to monitor lamp power. These meters will be calibrated to only one type of lamp and differ in their sensitivity. Thus, comparison between instruments from different manufacturers is not possible. If the spectrum of the lamp changes or if an

Quick and Easy Way to Characterize Low Voltage (80-125 kV) EB Accelerators Using Fast Check Strips

With the increased use of low voltage electron beam accelerators for curing coatings, inks, laminating adhesives and crosslinking films for packaging applications, there is an increased demand to accurately, quickly and easily measure the required dose delivered to the product. To meet this demand, Energy Sciences collaborated with S

Powder In Mould Coating as a superior finishing solution for SMC in automotive applications

This paper describes the powder in mould coating process (PIMC) in combination with sheet moulding compound (SMC). A powder coating is applied to a preheated mould to pre-gel. SMC is placed into the mould and pressed as one with the PIMC to cure together inside the mould. When the SMC is removed from the mould it comes out coated wit
