Storage stability inhibitor - extends shelf life with minimum effects on gel time (unsaturated polyesters).
Eastman™ DTBHQ (2,5-ditert-butylhydroquinone) is a crystalline solid that has low vapor pressure and short induction periods in peroxide-catalyzed polymerizations. Insoluble in water and caustic solutions, used as an antioxidant or co-inhibitor to prevent oxidation and extend shelf life in many industrial applications. Appearance: White to tan crystals Flash point: 216°C (420°F) Melting point: 215°C (419°F) Boiling point: 321°C (610°F) Specific gravity: 1.07 CAS: 88-58-4 Scavenges radicals slowly Storage stability inhibitor with minimum effect in gel time Stabilizes against odor and color development Used as a stopping agent in rubber emulsions and anti-skinning agent in paints.
Secondary inhibitor (co-inhibitor) and antioxidant for nonfood fats and oils.
Eastman™ MTBHQ (mono t-butyl hydroquinone) is commonly used as a polymerization inhibitor and antioxidant in many industrial applications. Effective in higher temperatures due to its higher solubility and potency compared to unsubstituted hydroquinone. Appearance: Light tan solid Flash point: 171°C (340°F) Boiling point: 295°C (563°F) Melting point: 125°C (257°F) Specific gravity 20°C/20°C: 1.05 Molecular weight: 166.22 CAS: 1948-33-0 Very effective polymerization inhibitor Good performing antioxidant in unstable organic liquids Excellent performance as a heat and stabilizer for pressure-sensitiveness adhesives Used as a polymerization inhibitor and industrial antioxidant in many applications.
Highly effective process inhibitor used in the production of highly reactive unsaturated polyesters.
Eastman™ THQ (Toluhydroquinone) is a tan to white crystalline solid that goes through similar chemical reactions as Hydroquinone. However, due to the presence of a methyl group in the ortho position, THQ becomes a highly active inhibitor in the free radical polymerization of vinyl monomers and unsaturated polyesters. Appearance: Off-white solid Flash point: 172°C (342°F) Boiling point: 279°C (534°F) Melting point: 127°C (261°F) Specific gravity: 1.3 Molecular weight: 124.13 CAS: 95-71-6 Better solubility in styrene than Hydroquinone Highly effective cook stabilizer in unsaturated polyesters Good performing antioxidant for oleates, linseed oil, and other nonfood fats and oils Used as an inhibitor, antioxidant, and intermediate manufacturing.
