Key Applications and UsesTriethylenetetramine (TETA) is extensively used as an epoxy curing agent, chelating agent, corrosion inhibitor, fuel additive, and in water treatment processes. Its unique chemical structure makes it valuable in a variety of industrial settings, where it supports durability, efficiency, and enhanced chemical performance.
Physical and Chemical CharacteristicsTETA is a liquid at room temperature with a refractive index of 1.4975 and viscosity of 21.3 mPas at 25C. It possesses a strong ammoniacal odor, is alkaline, and absorbs moisture from the air. Its flash point is 143C, and it has a density of 0.984 g/cm, making it stable for industrial handling with proper care.
Safe Handling and Storage GuidelinesDue to its corrosive properties, TETA must be stored in tightly sealed containers in a cool, dry, and well-ventilated location, away from heat and sources of ignition. Proper protective equipment is essential during handling to prevent burns. When stored as recommended, TETA maintains its quality for up to 24 months.
FAQs of Triethylenetetramine (TETA):
Q: How should Triethylenetetramine (TETA) be stored for maximum shelf life?
A: TETA should be stored in tightly closed containers in a cool, dry, and well-ventilated area. Keeping it away from heat sources and ignition points will help ensure a shelf life of up to 24 months.
Q: What are the main industrial applications of TETA?
A: TETA serves as an epoxy curing agent, chelating agent, corrosion inhibitor, and fuel additive. It is also used in water treatment processes, contributing to improved material strength and enhanced chemical resistance.
Q: When is TETA typically used as a curing agent?
A: TETA is used as a curing agent primarily in the manufacturing of epoxy resins, where its chemical properties help cure and harden resins for coatings, adhesives, and composite materials.
Q: Where can TETA be sourced for industrial purposes in India?
A: TETA is available through a network of distributors, exporters, importers, manufacturers, retailers, suppliers, traders, and wholesalers throughout India in commercially available drums or IBC packaging.
Q: What precautions are necessary when handling TETA?
A: Due to its corrosive nature, personal protective equipment such as gloves and goggles should be worn when handling TETA. Contact with skin or eyes may cause burns, so immediate washing and medical attention are advisable if exposure occurs.
Q: How does the hygroscopic nature of TETA affect its storage?
A: As TETA readily absorbs moisture from the air, it must be kept in tightly sealed containers to maintain purity and prevent degradation. Exposure to air can affect its efficiency in industrial applications.
Q: What are the benefits of using TETA in chemical processes?
A: TETAs high purity and versatile chemical properties make it ideal for enhancing epoxy systems, improving metal corrosion resistance, and optimizing chelation processes, resulting in cost-effective and durable industrial solutions.
