Polypropylenglycol-bis-(2-aminopropylether) - Amine Type Curing Agents

Amine types curing agents are derivatives from ammonia (NH3). They are named according to the number of amines in a molecule, like: mono-, di-, tri- and polyamines. According to the type of hydrocarbon involved, they are classified as:

Aliphatic - Aliphatic amine types curing agents can be selected to enhance the chemical resistance. In general, they are low viscous and have a low color impact on the film. This allows fast curing even at room temperature. Such products are:
- Aminoethylpiperazine
- Diethylenetriamine
- Triethylenetetramine
Through modifications they can have adjusted reactivity and targeted enhanced properties, such as:
- Chemical resistance
- Blush resistance
- Water spot resistance, or
- Adhesion

Cycloaliphatic - Cycloaliphatic amines from IPDA are one of the most commonly used curing agents for their excellent influence on chemical and mechanical properties. They can be used for low VOC coatings with:
- Fast cure rate
- Short pot life, and
- Low temperature curing suitability

Aromatic - Mannich type curing agents are usually amine types modified to get further improvement such as :
- Enhanced chemical resistance
- Influence the curing time, even under low temperatures
- Good adhesion, even on wet surfaces
- Longer pot-life

Aromatic amines have better chemical resistance than aliphatic amines.

Melamine curing agent will react with the OH functionalities at high temperature (above 140°C). Mainly used in stoving curing systems, this reaction can be accelerated using a catalyst.

Polypropylenglycol-bis-(2-aminopropylether) - Reference Information

LogP	1.34 at 25℃
EPA chemical substance information	information provided by: ofmpeb.epa.gov (external link)
Introduction	polyetheramine (Amine-TerminatedPolyether, abbreviated as ATPE) is a class with a soft polyether backbone, the Polyolefin compound is terminated by a primary or secondary amine group. Because the molecular main chain is a soft polyether chain, and the hydrogen on the end of the Polyether amine is more active than the hydrogen on the hydroxyl group of the Polyether terminal, the Polyether amine can be a good alternative to the Polyether in some material processes, and can improve the application performance of new materials. It is widely used in the field of polyurethane reaction injection molding materials, polyurea spray, epoxy resin curing agent and gasoline detergent.
Application	epoxy resin cured with polyetheramine has relatively long construction period, low exothermic temperature peak, colorless and transparent high gloss materials can be obtained, which can improve the state of the coating surface and is very suitable for casting and potting applications. Polyether amine cured product has good alkali resistance and water resistance, moderate acid resistance. Epoxy resins cured with polyetheramines have good electrical properties. Polyetheramines have unique properties, involving almost all epoxy applications, such as coatings, potting materials, building materials, composite materials and adhesives. Compared with other amine curing agents, polyether Amine has low viscosity, light color, good compatibility with many organic compounds, moderate reactivity, and can meet the special requirements.
preparation	acetoacetate groups are attached to both ends of the Polyether by transesterification with diketene or by Ethyl acetoacetate, the Polyether end-capped with an acetoacetate group is then aminated with a primary monoamine, an alkylalcohol amine or a primary diamine to give an imine compound having an aminobutenate end group and a very low viscosity.

Use and synthesis method of polyether amine

Introduction Polyether amine (Amine-TerminatedPolyether, abbreviated as ATPE) is a type of polyolefin compound with a soft polyether skeleton and terminated by primary or secondary amine groups. Since the molecular backbone is a soft polyether chain, and the hydrogen on the polyether amine end is more active than the hydrogen on the polyether end hydroxyl group, polyether amine can be a good substitute for polyether in some material processes. And can improve the application performance of new materials. It is widely used in polyurethane reaction injection molding materials, polyurea spraying, epoxy resin curing agent and gasoline detergent.
The physical and chemical properties are light yellow or colorless transparent liquid at room temperature. It has the advantages of low viscosity, low vapor pressure and high primary amine content. It can be dissolved in ethanol, aliphatic hydrocarbons, aromatic hydrocarbons, esters, glycol ethers, and ketones. And water and other solvents.
The epoxy resin cured with polyetheramine has a relatively long construction period and a low exothermic temperature peak, which can obtain a colorless and transparent high-gloss material, which can improve the state of the coating surface and is very suitable for casting and potting applications. Polyether amine cured product has good alkali resistance and water resistance, moderate acid resistance. Epoxy resin cured with polyetheramine has good electrical properties. Polyether amine has unique properties and involves almost all epoxy applications, such as coatings, potting materials, building materials, composite materials and adhesives. Compared with other amine curing agents, polyether amine has low viscosity, light color, good compatibility with many organic substances, moderate reactivity, and can meet special use requirements.
Preparation
First, use dienone or through the transesterification reaction of ethyl acetoacetate and polyether polyol, connect the acetoacetate group at both ends of the polyether, and then combine the acetoacetate group-terminated polyether with a mono-based primary amine, alkyl alcohol amine or binary primary amine is aminated to obtain an imine compound with a low viscosity as an amino butene ester.
