  43. 43. Water based paint for gloss enamel Options for 2011• Alternatives to solvent based alkyds• high solids (solvent based alkyds) – “alkyd like” (familiar) rheology – still significant solvent level needed (not “really green”) – difficult to achieve for tinted systems (coloured pigment distribution)01/02/2011
  44. 44. Water based paint for gloss enamel Options for 2011• Alternatives to solvent based alkyds – water based alkyds – no major change in chemistry (film properties) – no technical selling point vs. solvent based alkyds • “typical“ alkyd problems, such as yellowing, bad weathering performance 01/02/2011
  45. 45. Water based paint for gloss enamel Options for 2011• Alternatives to solvent based alkyds – water based acrylics • acrylic benefits (weatherability, whiteness) • limited gloss level 01/02/2011
  46. 46. Water based paint for gloss enamel Options for 2011• Alternatives to solvent based alkyds – water based PUs • good surface characteristics (chemical resistance) • expensive • limitations in achievable gloss level 01/02/2011
  47. 47. Water based paint for gloss enamel Options for 2011• Alternatives to solvent based alkyds – Polymer blends • combine benefits and deficiencies of different systems • need cobalt siccatives 01/02/2011
