UV-Curable Powder Coatings on 3-D, MDF Substrates - A New Technology
Uv-curable powder is very well suited for coating 3-dimensional objects made from medium densityfibreboard (MDF), typically for use in kitchen, bathroom and general furniture applications. In thispaper, the advantagesand limitations of uv-powder over conventional adhesive laminates and liquiduv-coatings are outlined. The physical and chemical requi
The Influence of Oxygen on Crosslinking Photopolymerization, Post Effect and Cooresponding Rate Coefficients
The inhibitory effect of oxygen on the radical photopolymerization is well known. Oxygen reacts with carbon —centered propagating radicals at the diffusion-controlled limit to form peroxy radicals much less reactive towards double bond, thereby reducing the efficiency of initiation. This generally leads to significant retardation (or even inhibitio
Smart Priming -Superior Adhesion of UV-cured Layers on Polymer Substrates
Many polymers, especially those without functional groups like polyethylene PE, polypropylene PP,polytetrafluoroethylene PTFE etc., need a pretreatment to alter their surface properties in order to improve the adhesion to other materials which are applied by subsequent coating, printing or laminating process steps. Conventional surface modifying te
UV - Basics Benefits and Market Trends
Although UV light curing technology has been used for over 30 years in the printing industry, it is still a new technology by comparison with conventional printing. More and more printers are converting to UV printing and the technology is being used in an increasing number of printing applications. Its growth rate is far above that of the printing
The Photoinitaled Polymerisation of 4-Methylene-1,3-dioxolanes
The radiation curing industry is searching for new polymerisable materials as alternatives toacrylates. Whilst acrylates possess many admirable features such as speed of cure, and there is a plethora of commercially available materials which give coatings having a wide range of properties, there is still concern about their toxicity and this is fue
Solvent effects in photografting MMA and CT complexs te cellulose, wool and plypropylrnr Significance of studies in radiation curing.
The role of solvents in photografting a typical methacrylate monomer, methyl methacrylate (MMA)to polypropylene (PPE) and cellulose is reported. A wide range of solvents of varying polaritieshave been studied for grafting to these substrates. The effect of additives which represent typicalcomponents used in radiation curing on the grafting reaction
Uv-Curable Acrylic Pressure Sensitive Adhesives Features, Mechanisms, Milestones
Although UV curing of acrylic pressure sensitive adhesives is known for more than 30 years, theinterest has grown rapidly in the last years 1]. The challenge to develop adhesive coatings free from organic solvents, while retaining the performance properties of solvent-based acrylic, is the major motivation in the concept of UV curing, It has been a
Deinking Of Recoverd Papers, Difficulties Related To Waterbased Inks And U.V. Varnishes
The aim of this paper is to describe some of the difficulties encountered when recycling indeinking plants in order to produce high-quality white deinked pulp (DIP). The deinking processrequires, after reslushing recovered papers, an optimal size of ink particles. This size depends onthe recycling techniques, but mainly on the nature of the ink.Fir
