• Environmental concerns ind increasing demands for ex-.ended warranty periods will make corrosion technology vitally important, Michael Vludge, European colour con3ultant with PPG (UK), told he British Carriage and Automobile Manufacturers annual :onference — Boditek '88 — at Keele University.
Pollutants released into the atmosphere when painting cabs and bodies will be reduced by more use of water-based prim, ar coats, two-pack non-toxic paints and poWder-based clear
coats, he told Boditek.
Pre-treatment of coated steels will use zinc alloy coatings while cathodic electropaint systems will become the norm, he said. These have better chip and rust resistance and can he applied at 25 to 45 microns thickness and need lower bake temperature.
The theme of the conference was "Body technology towards the 21st Century".
Computer-aided technology would broaden its application across all boundaries of the automotive industry, speakers told the conference.
Leyland Daf chief engineer Colin Ingram spoke of the increasing use of computers and fast colour screens showing shaded pictures threedimensionally, but nevertheless warned against obsession with technology.
IBM industrial specialist Frank Broad, while underlining the advantages of computer systems, said senior management must prevent "mini islands of select groups" forming. This point of view was echoed by MGA Developments managing director Mike Gibbs, Technology for an integrated approach is readily available, said Gibbs, but advances in design will allow full-size video projections, animations and holographs.
A development in vehicle glass will include de-icing windscreen, said BattelleEurope's L Colombin. This uses a vacuum-coated electrosensitive film of high light transmission producing up to 1,500 Watts. The film can be optimised to develop anti-solar properties simultaneously.
Attempts at replacing vehicle glass with acrylics or polycarbonates, said Colombin, have failed — but progress has been made.
