The chemistry of fast‐curing phenolic adhesives. I
Journal of Applied Polymer Science, 1973AbstractCertain low molecular weight, resinous polymers, such as those derived from phenol and formaldehyde, may be chemically modified with aromatic amines to produce other resins of physical properties similar to those of the original resins, but with chemical reactivity which is orders of magnitude faster than that of the unmodified resins.

Pigment & Resin Technology, 2001
UV‐radiation curing has become a well accepted technology which has found its main applications in the coating industry, the graphic arts and microelectronics. The liquid to solid phase change proceeds within a fraction of a second on intense illumination at ambient temperature.

The cure chemistry of polysulfides
International Journal of Adhesion and Adhesives, 1997Abstract Liquid polysulfide polymers can be cured by a wide variety of compounds and through a number of reaction paths. The most commonly used system is the oxidation of the thiol terminal groups in the presence of metal peroxides. Addition and substitution reactions are also possible with such diverse products as epoxy resins, isocyanates, acrylics

Studies on cure chemistry of new acetylenic resins
Macromolecules, 1993Cure studies of arylacetylene-terminated resins are described to gain some fundamental understanding of the influence of various structural aspects of a molecule on its cure chemistry. Of particular interest are the effects of the number of acetylenic substituents on the aromatic ring and their relative positions to one another.

Review of basic chemistry of UV‐curing technology
Pigment & Resin Technology, 2004The market for ultraviolet curing technology has been growing at double‐digit rates in the last 10 years. The main reason for such a rapid technological growth of UV curing is its unique process characteristic, which allow UV‐coating to be applied on virtually any substrates, including plastic, metal, composite, wood, paper, leather, vinyl, glass ...

The chemistry of fast‐curing phenolic adhesives. II
Journal of Applied Polymer Science, 1973AbstractNovolak‐like materials have been prepared by reaction of phenol–formaldehyde resoles with aromatic amines. The hydroxymethyl groups present in resoles react with the ring carbons and the amino groups of the aromatic amine. Proportions of the two types of product vary with the amine used.

The AGE of the matrix: chemistry, consequence and cure
Current Opinion in Pharmacology, 2004Accumulation of advanced glycation endproducts (AGEs) plays a crucial part in the development of age-related diseases and diabetic complications. AGEs are formed in vivo via the so-called Maillard reaction: a reducing sugar reacts with a protein to form a labile Amadori product that is subsequently stabilized, producing an irreversible, non-enzymatic ...

Vanilla- Its Science of Cultivation, Curing, Chemistry, and Nutraceutical Properties
Critical Reviews in Food Science and Nutrition, 2013Vanilla is a tropical orchid belonging to the family Orchidaceae and it is mainly used in food, perfumery, and pharmaceutical preparations. The quality of the bean depends on the volatile constituent's, viz., the vanillin content, the species of the vine used, and the processing conditions adopted.
