PEOPLE
SAFE USE, TRANSPARENCY AND INFORMATION
- Low VOC content (< 1wt.% acc. to ISO 11890-2)
- Free of human hazard label (non irritant to eye and skin)
- Free of alkyl phenol ethoxylates
ADDRESSING MEGATRENDS AND SOCIETAL TRENDS
- Reflects market trend towards low odor waterborne paints having less impact on the environment than solvent borne paints
- Suitable for hazard-label free formulations (acc. EU/CLP directive)
PLANET
RESOURCE EFFICIENCY AND ENVIRONMENTAL PROTECTION
- High active content: 70 %
- Effective at low use concentrations (usage in emulsion polymerization: 2 % active based on monomers; usage in paints: 0.1-0.3 %)
- Free of environmental hazard label
- Less impact on aquatic life (LC50 > 500 mg/l)
- Readily biodegradable (biodegradation > 75 % in 28 days according to OECD 301 D)
PERFORMANCE
INTEGRATED SUSTAINABLE BUSINESS
- Assistance in formulation development and regulatory guidance
PERFORMANCE ADVANTAGES
- Improves latex quality with longer shelf life
- Increases scrub resistance in paints
- Compliant with eco label criteria (European Ecoflower, German Blue Angel, Scandinavian Nordic Swan, French NF Environment)
- Easy to handle (low solid point and low viscosity of aqueous solutions)
