Vantex®-T… the zero-VOC, zero-odor, alkanolamine for waterborne paint

Vantex-T is a little different“VOC, the primary focus to make coatings greener.”

The Benefits of Vantex T 1 Safe & non-VOC Additive 2 Low Odor Alternative 3 Film Formation Capabilities 4 Water whitening 5 Emulsifier in SB alkyds

1 1) Safe & non-VOC additive Vantex-T is not a VOC by calculation or measurement Physical Properties Boiling Point 283°C Melting Point -70°C Vapour Pressure @ 20°C <0.01 mm Hg Molecular Weight 161.3

1 1) Safe & non-VOC additive There are a couple of non-VOC alternatives: R phrases Symbol Label R34: causes burns C Ammonia R50: Very toxic to aquatic organisms N R41 - Risk of damage to eyes R35: causes severe burns NaOH C R41 - Risk of damage to eyes Vantex T R41 - Risk of damage to eyes Xi - irritant Vantex T is NOT A SKIN IRRITANT according to Directive 2001/59/EC and to the UN Globally Harmonized System of Classification and Labelling of Chemicals

4 4) Water whitening Water based binders have a tendency to lose their transparency and become white when in contact with water for a period of time. Experimental Set-up • Unneutralized Styrene-Acrylic resin (pH=4) • Neutralise to pH = 7 to 8 Styrene Acrylic Resin • Application on black scrub paper Brookfield viscosity 20°C 3.800 mPa.s Total solid content 50,0% • Cure: 5 min @ 70°C pH 4,0 + rest 48 hrs @ 23°C Tg 18°C • Immersion in distilled water MFFT 14°C • Measure colour variation ( E)

5) Emulsifier in SB alkyds5 Why adding water to a solvent born Alkyd paint? • Reduce VOC level of paint (mainly Europe) • Reduce the cost of the paint What are the issues with adding water? • Storage stability: H2O separates from lipophilic paint • Drying: H2O interacts with dryer system Amines form complex with Co-dryer • Gloss: Gloss reduces when adding H2O • Viscosity: Viscosity build-up with addition of H2O

5) Emulsifier in SB alkyds5 Optimized formulation Ingredient Weight (%) Remark Long Oil Alkyd WS 43.2 Vilkyd 211W70 White Spirit 13.8 Bentonite 0.4 Bentone SD-1 Dispersant 0.4 Nuosperse 657 Titanium Dioxide 26.0 Tronox CR826 Nuodex DRYCOAT 1.6 Co-free Dryer system Rockwood Pigments MEKO 0.1 Exkin OXF H2O 14.0 Vantex T 0.3 VOC level = 295 g/L

SB Alkyds: potential for Vantex T ?!What about drying?The Recorders define stages in the drying process as:Stage 1 A pear shaped impression corresponding to thetime taken for evaporation of the solvent.Stage 2 The cutting of a continuous track, correspondingto a sol-gel transition.Stage 3 An interrupted track corresponding to the surface-dry time.Stage 4 The needle no longer penetrates the film,corresponding to the final drying time.

5) Emulsifier in SB alkyds5 What about drying? Nuodex Drycoat 6 Ca ; Sr ; CK10 5 Sr ; Co 4 Stage 1 Stage 2 Stage 3 Zn ; Ca ; Sr ; Co 3 Stage 4 LP 0455 2 Ca ; Sr ; Co 1 0 2 4 6 8 10 12 14 16
