Consortium publishes an overview of our work in Steel Construction

We have published an overview of the outcomes of a European-funded project called BarrierPlus. We developed a new type of water-based barrier coating was developed for structural steel applications, which included scaling the latex up to 15 kg quantities by an SME partner. A life cycle assessment found that the BarrierPlus coating has a better environmental profile than an industry benchmark solvent-borne coating and showed promising results relative to commercial waterborne benchmarks.

Steel Construction is the official journal of the European Convention for Constructional Steelwork (ECCS).

Strengthening a coating with a RAFT

The Lyon and Surrey teams have recently published work using reversible addition–fragmentation chain transfer (RAFT) polymerisation, to make tough, surfactant-free, latexes for coatings. The work was published in the leading journal Macromolecules. The paper by Lesage de la Haye et al., uses state-of-the-art RAFT polymerisation to avoid the use of surfactant — surfactant can reduce the water-barrier properties of the final film — while producing final film’s with high Young’s modulus.

BARRIER-PLUS will represented at Eurosteel 2017 by ECCS, please drop by!

Eurosteel 2017 will be in Copenhagen in September. This is the 8th European Conference on Steel and Composite Structures, and is part of a series that takes place every three years and is Europe’s leading conference on structural steel. The consortium will be represented at Eurosteel 2017 by ECCS. Please come along, we will be very happy to talk to you about our work developing one-component waterborne coatings for steel.

Consortium scientists uses computer simulations to study mixtures of many components

tmpppTypical coatings have not one or two, but several species of colloidal particles, and inevitably the particles of each component are not all made with identical diameters but with some spread of diameters. Andrea Fortini and Richard Sear of the consortium studied these effects using computer simulations, and their results have recently been published the American Chemical Society’s Langmuir journal.

Consortium probes coating with neutrons

isis_bpteamIn April 2016, a team from the University of Surrey conducted experiments on Barrier-Plus materials at the ISIS pulsed neutron source at the Rutherford Appleton Laboratory. They used small angle neutron scattering (SANS) to understand the film formation of surfactant-free latex. These materials were labelled with deuterium, a heavy isotope of hydrogen, by the team at the Université Claude Bernard Lyon 1 and CNRS so that the molecular structure inside the barrier coatings could be revealed. At the left, we have the team working at ISIS at the Rutherford Appleton Laboratory. From left to right: Phil Richardson, Nacho Martin-Fabiani, David Makepeace, and Joe Keddie.
