SOLVENCY
CHARACTERISTICS OF DMS
Dimethyl
sulfide (DMS) is a nonpolar, stable, water-white organic solvent which is
capable of
dissolving a wide range of both organic and inorganic materials. In general,
DMS will dis-
solve the following organic materials:
Ethers
Amines
Esters
Monobasic
organic acids
Alcohols
Rosins
Ketones
Polyisobutyl
methacrylate
Aromatic
hydrocarbons
Polystyrene
Aliphatic

Polybutylene
Halogenated
compounds
