Adrian Beard and Volker Thewes, both experts on flame retardants at Clariant Produkte (Deutschland), explain how inorganic systems substitute halogens and what latest technical developments are basedon.
Biocides need registration. In the case of algicides, diuron seems to fulfil all necessary requests as a study shows. Frank Sauer, Head of Technical Marketing at Lanxess, comments on the growingnecessity of this kind of biocides.
Talk about new active ingredients as well as delivery systems and controlled release technologies are being developed to address needs for in-can and dry-film preservation, as well as for newapplications such as antimicrobial surfaces at ECC "Novel Biocide Technolgoy IV”

Two-way benefits
A newly introduced neutralising amine for waterborne coatings, secondary-butyl ethanolamine or sBEA, has an amphiphilic structure, through which it can assist dispersants in separating and binding topigment particles. Tests on a blue tinting base show that sBEA provides greater pigment efficiency and better flow properties than classical amines such as DMEA.
