Page 14...An eco friendly removable grass paint (more class than grass)

by Mark Slater

All major sporting arenas paint signs on their field grass for advertising.  Up until now the ads were virtually non-removable and had to be painted over in green paint.  Signs were often paint on signs and previous signs were evident underneath or would show as shadows on TV.  Environmental considerations are now paramount for all such venue, even golf clubs and airports as lakes, dams and rivers are often nearby.  There is already a move to specify only genuinely removable coatings at the venues.  Shieldcoat spent some 18 months researching possibilities that meet the requirements of removability at will, anywhere from 1 day to 30 days, and that will not damage the grass.  A 9000 Square metre sign (the largest in the world) was undertaken at Brisbane Airport demonstrating fast airless application.  It was completed in under two days thus showing the way for large signs to be a viable marketing opportunity.  The removability, speed of application and environmental solution provided will open up further markets at major airports, car and horse racing tracks, and gold clubs and tournament circuits.

Page 16...Easy dispersible pigments - a new cost efficient way to disperse pigments

by Tim Boyce, Wolfgang Winter and Chong Su Fah

ED (easy Dispersible) pigments are powder pigments which have been specially surface treated using proprietary technology.  By using ED pigments, it is now possible to disperse organic pigments with a dissolver without any milling process.  In these times when "cost down" is of paramount importance to the paint manufacturer, these pigments offer an ideal opportunity to reduce energy cost and increase factory throughput, and generally simplify teh production process.  This paper deals with the available range of products for solvent based paint systems, teh processing techniques of using them and subsequent benefits for the customers.
