Aesthetics – minimizing the effect of coating degradation

  • The main drivers are to provide customers with best in class initial appearance and reduced maintenance/repair/repaint requirements
  • We seek technologies which could further minimize the effect of coating degradation/appearance by in-service/environmental conditions
  • Current state of the art coatings are based on polyester, acrylic urethane, acrylic polysiloxane and alkyd/modified alkyd resin technologies which are very effective with well-established track records. Introduction of alternative technologies could be a challenge but also potentially an opportunity
  • Current technology is 40-80% volume solids and the general trend is towards higher solids or solvent free. This presents a challenge to maintain acceptable initial appearance and in-service performance attributes
  • Common substrates are mild steel, aluminium, wood and GRP pus a range of coating technologies (fresh and aged)
  • Other key features include high initial gloss, excellent opacity, good edge coverage, abrasion and impact resistance
  • Surface tolerance/self-cleaning properties and resistance to dirt pick up would be desirable features in order to improve ease of maintenance and repair and reduce in-service costs
  • Easy application by brush, roller and spray application over properly prepared surfaces should be possible in order to achieve best in class initial cosmetic appearance
  • Extensive over-coating (maximum overcoat window) would be a benefit for customers in terms of flexibility of working practices
  • The ability to apply and use coatings at low temperatures ( 5°C and below) could provide a benefit to customers
