Dispersing Agents for the Digital Revolution in Printing Inks

TEGO® Dispers products have historically proven themselves in numerous coating and printing ink formulations. However, new and challenging applications are constantly being presented, and the products must be able to satisfy the latest demands. Of these, the use of digital printing across a variety of substrates – especially textiles and ceramic tiles – has come into focus and taken priority wi...

Additives in adhesive formulations Wetting Agents – boon or bane ?

Pressure-sensitive adhesives or PSAs are traditionally used on labels, including paper labels and clear labels, Figure 1, which are made from plastic film. Other important uses for PSAs include adhesive tapes and a wide range of graphical applications. One factor that all these applications have in common is a specific requirement relating to the end performance of the adhesive system, which is...

Properties of the cholera exo-enterotoxin: effects of dispersing agents and reducing agents in gel filtration and electrophoresis.

Initial studies, by using polyacrylamide gel electrophoresis in the presence of sodium dodecyl sulfate (SDS), led to the attractive hypothesis that the cholera exo-enterotoxin (choleragen) consisted of two noncovalently linked peptides of 56,000 and 28,000 molecular weight. The spontaneous toxoid (choleragenoid) appeared to be identical with the 56,000 molecular weight piece. The results appear...

Studies on the Action of Wetting Agents on Microörganisms: I. The Effect of pH and Wetting Agents on the Germicidal Action of Phenolic Compounds.

Soaps have been extensively used, often with added alkali, to emulsify or make soluble phenolic compounds of limited solubility (Klarmann, Shternov and Von Wowern, 1929; McCulloch, 1936). There is, however, a good deal of controversial information in the literature dealing with the effect of soaps on the germicidal action of phenolic compounds. Frobisher (1927) reported that small amounts of so...
