Name: Eastman TMA-40 40% Trimethylamine Solution Trimethylamine 40% Solution
Brand: Guangzhou Eric Wei Chemical Co., Ltd.

Features Of Eastman TMA-40 40% Trimethylamine Solution Trimethylamine 40% Solution

Stable, aqueous solution containing precisely 40 wt% trimethylamine (TMA), optimized for consistent reactivity and handling safety.
Manufactured under strict Eastman quality control to ensure low levels of impurities such as dimethylamine and methylamine.
Engineered for reliable performance in quaternization and catalytic reactions requiring controlled amine strength and volatility management.
Supplied in UN-approved, corrosion-resistant packaging suitable for industrial-scale chemical transfer and storage.
Offers improved process safety versus anhydrous TMA due to reduced vapor pressure and minimized inhalation hazard.
