Key properties of the GalasterTM

biosolvent range

All GalasterTM solvents share the following properties:

1. Organic

2. Protic and Polar:

CH3 C C

H

O

O Et

OH

2. Protic and Polar:

� OH function free – Hydrogen atom able to form hydrogen bond

3. Oxygenated

� Ester alcohols

� When longer chain alcohols are used for synthesis, the solvent is more likely to be non polar

� This explains why Ethyl hexyl Lactate is not soluble in water as opposed to Ethyl lactate

Additives for solvent-based products

• As we’ve just seen, Galasters are very high polar solvents and show high solvency power with regard to polar polymers (vs. acrylic, epoxy, acetate, .... resins), their use in solvent based formulations is possible

� As co-solvents in high solid paintsAs co-solvents in resins� As co-solvents in resins

� As additives in chemical formulations

� To increase open time, to control evaporation, to slow down drying time

– (High boiling point solvent – Slow evaporation rate)� To improve the wetting properties

– (Contact angle improved on PVC, …)

Paint/Varnish Stripper

Galaster EL98 is currently used in various paint/varnish stripper formulationsSolvency power of EL98 is generally not sufficient to cover the stripping of all type of paints and varnishes.As the molecule size is too big, EL98 is use as co-solvent in combination with a powerful solvent.

Typical formulations

1.Paint Strippers:- Ethyl Lactate / DMSO / Blend of high aromatic solvents- Ethyl Lactate / DMSO / DBE (dicarboxylic acid ester)2. Varnish Strippers:- Ethyl Lactate / d-Limonene

Graffiti removers

Ethyl lactate has been tested in several formulations. In combination with Ethyl soyate, it’s highest efficiency has been shown for markers, lipstick, correctional fluid, spray paint on unpainted & painted smooth surfaces (non porous) and least efficiency on wood and painted concrete.

Before and after using SOYsolv® blend of Ethyl lactate, let it rest for about threeminutes, and then wipe with a scratchless scrub pad.Source: http://www.responsiblepurchasing.org/publications/Grafitti_Report.pdf
