Powder coatings.(part 3)
July 1, 1999... Powder coating is undergoing rapid growth. Worldwide production of powder coatings in 1996 was estimated to be about 450,000 metric tons.[1] Powder coatings are used most extensively in Europe and Japan; North American production in 1996 was...

Cure of secondary carbamate groups by melamine-formaldehyde resins.
July 1, 1999... INTRODUCTION Amino resins are reported to be the predominant crosslinking agents for thermosetting industrial coatings, and melamine-formaldehyde (MF) resins are the most widely used type of amino resin.[1] MF resins have been used...

Photocuring activity of several commercial, near UV activated photoinitiators in clear and pigmented systems.
July 1, 1999... Some of the most important commercial near UV photoinitiators have been analyzed by UV spectroscopy to evaluate the type of electronic transitions occurring upon absorption of light. Photocuring studies have been undertaken by real time...

UV-curable, special coding inks for optical fibers.
July 1, 1999... A UV-curable, special coding ink for optical fibers consists chiefly of UV-curable prepolymers, coloring materials, and a photoinitiator. The UV-curable prepolymers are silicone epoxy benzoic acrylate (SEBA) and alicyclic hydrocarbon epoxy...

Application of digital image analyses to measure print quality.
July 1, 1999... An important aspect of poor print quality in high-speed printing is color density variation in solid print areas, which is described as mottle. Armel and Wise provide a more detailed description and the various types of mottle.(1)...

The coating chemist as expert witness.
July 1, 1999... Introduction The call for a chemist to serve as a technical expert in legal matters is fairly common and the expert must address various questions in the field of polymer and coatings science. The referrals often come from: a coatings or...
