For optimum ultraviolet (UV) curing efficiency, the material to be cured must match the specific spectral output of a UV bulb. This output, measured in nanometers at each wavelength throughout the UV range, is the defined spectral measurement used to quantify one UV bulb type from another. Each bulb has its own unique characteristic,

UV powders are generally based on unsaturated (meth)acrylate polyesters and urethane (meth)acrylates, photoinitiators and additives (pigments or fillers). All compounds are solids, which make the formulations environmental friendly.The objective of this work is to correlate the formulations characteristics with the photochemical proc

UV-initiated cationic curing is a way to create useful materials for coatings, sealings and adhesives in diverse application areas. From the past three decades up to now several special development examples are presented from the field of electronics and electro technology.For optimum results from reactive resin chemistry it is neces

The synthesis of organic-inorganic sol-gel coatings was performed using alkoxysilanes bearing either an epoxy or a methacrylate reactive function. These hybrid materials combine numerous advantages such as good adhesion to substrates, abrasion and chemical resistance. Usually, they are synthesized through the successive conventional

• AFP-coated stainless steel is a high-end “design” product.• The trend for the adoption of AFP stainless is growing (future?)• Quality and function requirements are extremely high.• UV-cured coatings help reduce the “plastic-like” effect of AFPs.• Also: reduction of surface defects, energy consumption, emissions.

Cellulose-based materials are one of the most widely used materials provided by nature to mankind. In particular, cotton fibres have been used for millennia to produce clothing items due to its properties such as hydrophilicity and permeability to water vapour. However, increasingly sophisticated uses for cotton-based clothing (e.g.

Coil coating - a modern way of applying paint to the metal roller facing materials. Coating process is carried out on automated production lines. The technology was invented in the U.S. 60 years ago. In the production of profiled metal sheets there are practically no competitors.

Graphene, a new class of two-dimensional sp2 carbon nanostructure, holds great promise for potential applications in many technological fields such as optoelectronics. One of the most common preparation method of graphene starts from the oxidation and exfoliation of graphite oxide to graphene oxide (GO). raphene oxide sheets consists
