Hydroxyl-free solvents for polyurethane
Hydroxyl-free solvents for polyurethane:
ASTROBIO™ NV, sample on request.
ASTROBIO™ NV grades are sustainable, bio-based solvent blends that are completely hydroxyl free, so they are compatible with systems containing reactive -NCO groups. They are used to formulate urethane coatings, adhesives, paints and inks, and bio-based paint strippers, PU cleaners and industrial detergents. The family has six grades: NV, NV3, NV5, NV9, NV11 and NV13.

ASTROBIO™ NV grades are completely hydroxyl free, so they are compatible with systems containing reactive -NCO groups.
6 grades
The NV family has six grades with the same functionality and a different evaporation rate: NV, NV3, NV5, NV9, NV11 and NV13.
Safer
ASTROBIO™ NV is safer than other urethane grade solvents due to its hazard statements, GHS and CLP classification.
2006
Astrobio has been developing bio-based solvents in Italy since 2006.
Six ASTROBIO™ grades, one hydroxyl-free family.
The six NV grades have the same functionality and differ in evaporation rate. Tell us your process and we suggest which one to test first.

NV grades
Hydroxyl free, for -NCO systems
ASTROBIO™ NV, NV3, NV5, NV9, NV11 and NV13 are hydroxyl-free specialties for polyurethane (PU) coating formulation and for cleaning. They have the same functionality and a different evaporation rate (RER). No single solvent is replaced: you choose the grade that suits your process.
Technical data sheet of NVThe evaporation rate and the other values of ASTROBIO™ NV are in its technical data sheet, available after registration. For the other grades, ask our chemists.

Chemistry
Completely hydroxyl free
ASTROBIO™ NV grades are completely hydroxyl free specialties, so they are compatible with systems containing reactive -NCO groups. Solvents that carry hydroxyl groups can react with -NCO groups, which is why urethane systems call for hydroxyl-free solvents.
Origin
Bio-based, from renewable raw materials
ASTROBIO™ NV is a sustainable, bio-based solvent blend of organic acid esters, made from renewable raw materials.
Safer
A safer choice among urethane grade solvents
ASTROBIO™ NV is safer than other urethane grade solvents due to its hazard statements, GHS and CLP classification. Check your specific case against the safety data sheet.
A summary for orientation, not legal advice: always check the current texts and your safety data sheets.
ASTROBIO™ NV works in -NCO systems with a lighter label.
