SEC BUTYL ALCOHOL
Sec-Butyl Alcohol
SEC BUTYL ALCOHOL is a clear liquid with characteristic odor, partially soluble in water and completely miscible with most organic solvents, such as esters and other alcohols. Its evaporation is moderate at room temperature.
Other denominations: sec-butyl alcohol, 2-butanol and sec-butanol.
CAS 1 number: 78-92-2.
SEC BUTYL ALCOHOL has the following advantages:
•
It is not listed as a HAP to the MIR 3
2 product;
•
Low VOC (volatile organic compound) emission due to low photochemical reactivity, according
scale;
•
Low toxicological potential;
•
Biodegradable;
•
Low retention in flexible films (polyethylene and polypropylene), reducing blocking after painting, with better organoleptic advantages than that of n-butanol and isobutanol;
•
Enables better solubilization of resins, allowing less viscous formulas and/or with less active solvents;
•
With regard to the dilution rate (toluene), it helps the active solvent in accepting diluent.
Regarded as a linking agent, it has better performance compared to n-butanol and isobutanol (60% soluble in water);
•
Low retention in flexible packages (application of flexographic inks).

2. HAP: Hazardous Air Pollutants
3. MIR: Maximum Incremental Reactivity values for quantifying relative ground-level ozone impacts of volatile organic compound
(VOC).
Leathers
SEC BUTYL ALCOHOL can be used as co-solvent, evaporation retardant solvent for leather finishing.

Due to being highly flammable, SEC BUTYL ALCOHOL must be protected from any sources of ignition, such as open flames, hot surfaces and electric discharges. It is not corrosive, therefore, it can be stored in grounded, common carbon steel tanks. It is advisable to handle the product in ventilated places or places with exhaust.
The use of personal protection equipment, such as PVC gloves, coat and safety goggles, is recommended during handling. In case of prolonged exposure, use masks appropriate for organic vapors.
The extinguishing agents are dry chemical powder, carbon dioxide and foam for polar solvents.
The shelf life of SEC BUTYL ALCOHOL is 24 months as of the manufacturing date, provided it is kept in the original pack and in suitable storage conditions.
