TMQ

Antioxidant TMQ

2,2 ,4-Trimethyl- 1 ,2-dihydroquinoline,

CAS NO.:26780-96-1
Chemical Molecular ( C 12H15N)n

Chemical Structure

APPLICATION
A rubber antioxidant. A kind of amine antideteriorant. The property of anti-heat oxide is good. A radical scavenger in a
wide range of elastomers to protect against oxidative aging. TMQ provides oxidation protection to nearly all elastomer types
in a variety of applications, having a wide range of temperatures exposure. The long persistence in rubber allows it to provide
long term heat aging resistance to rubber compounds. Inhibits oxidation catalyzed by heavy metals such as copper and
manganese. As a result of its high molecular weight, it migrates slowly within the rubber matrix and does not bloom. Used in
light compounds, but will cause some minor discoloration. It causes only minimal staining.
HANDLING PRECAUTIONS
For detailed information on toxicological properties and
handling precautions please refer to the current Safety Data
Sheet.

STORAGE RECOMMENDATIONS

Store TMQ in single stacked pallets in a cool, dry,
well-ventilated area, avoiding exposure of the packaged
product to direct sunlight. Double stacking of palletized
material and/or exceeding 3 5 c a n result in unusual
compaction of product.
PACKAGING: 25kg paper bag.
