  • 1. Environmentally friendly Dispersions for Paints Our Path to Greener Paints…….Dr. Satish GaonkarDispersions & PigmentsBASF India Ltd 01/02/2011
  • 2. ContentsPart 1: Low VOC, odorless paint for premium Interiors • Driving force for Low VOC/odorless paint • Role of Dispersion • Comparison • Value CurvePart 2: Water Based paint for Gloss enamel • Present scenario • Comparison of Different chemistries • Whats the future01/02/2011
  • 3. Zero VOC & Low VOCAccording to EPA (Environmental Protection Agency) standard• Technically, the term “zero VOC” paint applies to paints that have < 5 g/L of VOC.• The term “low VOC” paint has been applied to paints having a wide range of VOCs from 30 g/L to as much as 250 g/L01/02/2011

  • 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. 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. 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. 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. 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
