SeperatorCoasol™ is a mixture of Di-Isobutyl Succinate, Di-Isobutyl Glutarate and Di-Isobutyl Adipate.

Di-Isobutyl Succinate      % w/w       10-25

Di-Isobutyl Glutarate      % w/w       45 - 65

Di-Isobutyl Adipate        % w/w    10 - 35

Total diester content       % w/w      min. 99

Coasol™ is positioned as a superior replacement to the 2,2,4-Trimethyl-1,3-pentanediol Monoisobutyrate. Coasol™ has a boiling range of 274°C - 289°C, as against the prevailing Pentanediol Mono Isobutyrate Esters (i.e. Texanol, UCAR Filmer IBT, NX795) which have boiling ranges in range of 255°C - 261.5°C. Coasol™ is said demonstrate and replace the Pentanediol Monoisobutyrate Esters with an efficacy of upto 50% (The benefits of the Coasol™ vary depending on the resin systems used by the Paint Formulator).

Advantages of the Coasol™ v/s prevailing Pentanediol Mono Isobutyrate Esters are as below

High Eco-Tox Profile

  • Non-VOC, biodegradable and low odour ‘on wall’.
  • Coasol™ isn’t toxic and is Non HAPS (Hazardous Air Pollutant).
  • No esters of butyric acid so no risk of unpleasant odours when paint applied to alkaline walls.

High Performance & Efficiency

  • Can use 20-50% less than the Texanol (depending on the resin system) to achieve a low MFFT.
  • Reduced solvent loading to allow incorporation of open time extenders and freeze/thaw protection systems.
  • Improved paint rheology and pigment wetting
  • Incorporated easily in low shear mixing
  • Minimal water solubility improves portioning performance

Enhanced film properties

  • Improved open time enhances film formation
  • Film integrity and durability improved by drying profile
  • Excellent water resistance
  • Improved colour development & minimal impact on gloss
  • Improved film hardness without cracking
  • Improved wet rub performance
  • Resistant to hydrolysis so useable on Alkaline surfaces
