Transcript

  • 1. Neutralizing amine beyond your imagination JJ chemical customer day 22 June 2010
  • 2. Typical reasons to use amine How about low VOC solution??
  • 3. The total zero-VOC Solution
  • 4. ® Benefits of Vantex®-T 1) No odor 2) Zero VOC additive according to both EU and EPA definition 3) Further reduce VOC/odor by partially or completely replacing coalescent solvent 4) Co-dispersing performance 5) Excellent storage stability (pH/Color/Viscosity) 6) Enhanced Freeze-thaw stability 7) Open time extension
  • 5. Major physical properties highlight Vapor Pressure mmHg 20 <<0.01 Molecular Weight (g/mol) 161.3 Boiling point at 760 mmHg (283 ) Similar to most coalescent solvent! Freezing point at 760 mmHg (- 70 ) Base strength (pKa @ 22 in water) 8.9
  • 6. Coalescent performance Two angles to demonstrate 1. Minimum Film Formation Temperature (MFFT) study of PURE LATEX and ACTUAL FORMULATION 2. Low temperature cracking study
  • 7. MFFT study of pure latex Emulsion Primal AC-261P Test method MFFT of AC-261P was measured under different loading of Vantex-T Vantex-T loading MFFT ( ) 0% 18 1% 15 3% 10 5% 10
  • 8. MFFT study of pure latex Emulsion Primal dirtshield K2 Test method MFFT of K2 (500 parts) was measured under different loading of Vantex-T Vantex-T loading MFFT ( ) 0% 50 2.4 % 40.3 4.8 % 21.4 9.6 % 11.8 * At least 9.6 % (48 parts) of Texanol is needed to reduce the MFFT of K2 to 0

More than 70% replacement is possible with AC-261P.
  • 10. 100% replacement of coalescent solvent Component Part per weight AMP-95 0.38 ------ Vantex-T ------ 0.38 0.38 DALPAD C (Coalescent additive) 0.6 ------ VANTEX-T ------ 0.6 0.22 EcoVAE 1608 28 28 28 MFFT 4.4 3.5 4.6 Reference formula of a low odor product selling in market *Almost the same MFFT was showed by using Vantex-T to 100% replace the coalescent solvent
  • 11. Low temperature cracking study Paint films are commonly evaluated as “draw-downs” (rectangular patch of paint applied to a surface at a set thickness). One common test involves assessing the number of cracks that develop in a paint film that is dried at low temperature (4 ). A value of 10 = no cracks, 1 = cracks over the entire surface.

  • 14. Commercial case of 100% take out glycols by using Vantex-T "I have had a chance to evaluate the Vantex T in several different formulas and I am very pleased with the results. I am actually currently using it for a new low VOC paint formulation project. I have used the Vantex T in three separate formulas with three different resins and in each case I have been able to achieve good film build without the use of any glycols. I have already recommended the Vantex T as part of a formulation and will continue to do so as long as the results stay this positive. Thanks again for the sample. I'm sure I will be needing another soon, as I have been using it so frequently."
  • 15. Comment from Coating Research Group Inc in the US “Compared to NH3/other amines, Vantex-T was comparable in paint performance. There were no yellowing issues. Important value is Good coalescent effect that other amines do not have.”
  • 16. Co-dispersing benefit 1. AMP as industrial standard 2. Two hydroxyl group to further enhance pigment dispersion
