Introduction and application of CAS: 542-28-9 | delta-Valerolactone
Delta-Valerolactone is a multi-purpose chemical intermediate and is used in different fields. It is mainly used to replace caprolactone in inks and coating additives. delta-Valerolactone replaces caprolactone in inks and coating additives. The inks and coatings produced have the advantages of better viscosity reduction and non-solidification at low temperatures than those produced using only caprolactone.
