Hybrid Photoinitiator Sensitization
The sensitization of 3 photoinitiators was studied by FTIR spectroscopy. The tested initiators were: HP1 – (5-2,4-cyclopentadien-1-yl){(1,2,3,4,5,6-)-{-[4-(2-hydroxy-2-methylpropanoyl)-phenoxy]ethoxy}-benzene}-Fe(II)-hexafluorophosphate) prepared in our laboratory and two commercially available photoinitiators for comparison (radical ph

How to decide on the right UV primer for wood
For industrial parquet applications, 100% UV coatings have been very well established as primers, sealers and topcoats for many decades. They combine ultimate productivity, high quality and very low VOC. Another option is the use of waterborne UV primers in combination with 100 % UV sealers and topcoats. Waterborne primers are used d
Visible light photoinitiating systems using borate salts as coinitiators applied to the laser imaging area
This paper describes the photochemistry of visible light photoinitiating systems (PIS) developed for free radical photopolymerization (FRP). These PIS consist of borate salt used as coinitiators combined with different dyes absorbing the UV-visible range. It was shown, that these systems lead to high rates of polymerization and high
High performance radical and cationic initiators with low emission properties
High UV curing performance alone is no longer sufficient for sensitive applications. Low emission and low migration have become critical requirements for photoinitiators. A new, tetrafunctional -hydroxyketone radical photoinitiator showing a unique combination of low migration and high cure speed in spite of its high molecular weigh
High Performance Fillers in Wood Coatings and Decorative Melamine Films
The usage of micronized fillers in UV curing parquet lacquers is not common due to lack of transparency. Nevertheless there is the tendency, to use fillers more and more to increase scratch resistance and for cost reduction reasons.Nano additives are able to increase scratch resistance but the usage cannot be recommended in term
Globally Harmonized System (GHS) of classification & labelling of chemicals
GHS is a global system for standardizing and harmonizing the classification and labelling of chemicals, which has been developed and agreed at UN level. It defines physical, health and environmental hazards of chemicals and creates classification processes that use available data on chemicals and mixtures for comparison with the defi
Frontal polymerization using UV curable resins
State of the art light-curing polymer fillings are good alternatives to amalgam dental fillings due to their very short curing time and their suitability towards mechanical and esthetic requirements. One of the important problems that is associated with these types of materials is the limited penetration depth of light which causes p
