The dearomatised paraffin that ASTROBIO™ K40 is made to replace.

Origin

A bio-based blend instead of a petroleum paraffin

ASTROBIO™ K40 is a bio-based solvent blend developed in Italy since 2006 as an alternative to the petroleum-based dearomatised paraffin D40.

Evaporation

Slow evaporation, high boiling point

ASTROBIO™ K40 has a high solvent activity, a slow evaporation rate, low density and a high boiling point, and it dries completely and leaves no residue. The measured values are in the technical data sheet.

Safer

Safer than D40

ASTROBIO™ K40 is safer than D40 due to its hazard statements and GHS and CLP classification. Check the classification of your current D40 in its safety data sheet.

A summary for orientation, not legal advice: always check the current texts and your safety data sheets.
