High purity solvents
Oxygenated Solvents
SEQENS offers a range of high quality oxygenated solvents.
Upstream integrated in high quality acetone we have developed unique own technology to produce
- Isopropanol (CAS 67-63-0), 5 grades: Techincal, Cosmetic, Pharma GMP (EXCiPACT certified) Electronic, Recovered
- Isopropyl acetate (CAS 108-21-4)
- Di isopropyl ether (CAS 108-20-3)
Our oxygenated solvents are of low toxicity, environmentally friendly and several are non VOC, allowing wide formulating opportunities.
Low VOC Solvents
Everybody is familiar with the strong and distinct odour of paint and nail varnish remover. These odours are due to certain compounds evaporating. The ability of a compound to evaporate is known as its volatility. A Volatile Organic Compound or VOC is a carbon-based chemical that has the tendency to evaporate quickly. This speed of evaporation makes them difficult to work with and can cause harmful effects, not only to the environment but to health. Therefore low or non VOC solvents have become increasingly important for industrial purposes. One of those applications being paints and coatings into which Seqens offer our non VOC Coasol ® range of coalescent products.
Other solvents
- Diisopropyl adipate (DIPA) – CAS 6938-94-9
- Speciality solvent in household cleaners. Function as low temperature resistant and low viscosity plasticizer for PVC and its copolymers and cellulose esters.
- Dimethyl adipate – CAS 627-93-0
- A low toxicity, low odour, non VOC, readily biodegradable solvent that can be used in a variety of applications including agrochemicals, polymer intermediates, screening creams and lotions.
- Ethylene glycol diacetate – CAS 111-55-7
- A colourless, low odour solvent with a very slow evaporation profile that finds major applications in foundry core-binding and in thermoplastic acrylic coatings.
- 2-Ethylhexyl acetate – CAS 103-09-3
- A clear, high boiling polar solvent with low volatility, suitable as a carrier solvent for nitrocellulose production and many other natural and synthetic resins used in a wide range of industrial applications.
- Di-n-butylether (DnBE) – CAS 142-96-1
- A speciality solvent that is finding increasing use as a replacement for THF in Grignard, Wittig and other organo-metallic reactions and is used in the production of CD-R.
