This article will discuss what is cycloaliphatic amine epoxies, the curing agent, and their physical, thermal, and chemical properties. You’ll also learn about the mercaptan curing agent. If you’ve been asking yourself, “what is cycloaliphatic amine epoxy?” you’re not alone. There are many other questions you might have, too.
Cycloaliphatic amine epoxy
Cycloaliphatic amines, such as XTA-801 Amine, are a new type of highly reactive cycloaliphatic amine epoxy. These new resins are capable of delivering enhanced glass transition temperature, chemical resistance, modulus, hardness, and abrasion resistance. This resin is suitable for ambient curing, and is manufactured by Huntsman Performance Products. Its primary products include amines and alkaline carbonates, a range of surfactants, dispersants, and latex paint amine neutralizers.
APCHA is an important ingredient in cycloaliphatic amine epoxy formulations. It has good thermal and mechanical properties, and outperforms other cycloaliphatic amines. It also provides lower viscosity, extended pot life, and a reduced exothermic during curing. This material also works well in combination with other primary and secondary amines to provide a versatile coating system.
Mercaptan curing agent
Among cycloaliphatic amine epoxy hardeners, mercaptan is the most common. Its role is to control the speed of cure and flexibility of the final product. Its amine-based counterparts are usually formulated with amidoamines. Currently, the amine-based cycloaliphatic amine epoxy market is dominated by BASF, which is one of the few companies to handle this technology and offer a broad portfolio of amine-based curing agents.
The Polymercaptan Resin curing agent in a cycloaliphatic amine epoxy is derived from a polyiodide with more than one epoxy functional group. Its synthesis is a stepwise process, whereby an epoxy group is converted to a halohydrin group through the reaction with hydrogen sulfide. The halohydrin group is then formed by reacting with sulfhydride.
Physical, thermal and chemical properties
Polyamines form the majority of curing agents used in two-part epoxies. Polyamines include cycloaliphatic amine, diethylene thiamine, and polyether amides. Other curing agents used in DGEBA adhesives are mercaptans. A five-minute epoxy adhesive cured with mercaptan showed a significant peel strength.
Modified cycloaliphatic amines are the most commonly used curing agents in epoxy resins today. They exhibit good curing properties and fast curing rates compared to aliphatic amines. They exhibit excellent resistance to solvents and high temperatures, and are used in coatings where low or high-level oxidation is an issue. They also have good bonding performance and mechanical properties.
Reactivity: The reactivity of the formulations was determined using a Brookfield viscometer (RV-27). The test used twelve grams of cycloaliphatic amine-epoxy resin composition. The temperature range of reactivity was 40 degrees C. The temperature was then adjusted to achieve the desired level. A typical cure time of an epoxy system using APCHA is between two and four hours.
The cycloaliphatic amine is a chemical compound that is typically blended with Epoxy Curing Agent resins at room temperature to accelerate the curing process. These amines are highly reactive and provide excellent curing performance, though the post-curing temperature is a critical factor. As a result, the cured thermoset is hard, with excellent bonding properties. Listed below are a few advantages of cycloaliphatic amines.
In certain applications, such as marine construction, the application of amine-epoxy coatings has the potential to enhance the performance of the composite material. While cycloaliphatic amines cure at room temperature, their reactivity increases when they are used in the post-curing process. This property may prove useful in marine applications where fast drying and corrosion resistance are vital. However, these benefits should not be overlooked.
Cycloaliphatic amines are used for a variety of applications, including floor repair systems, sewage treatment plants, and industrial and commercial flooring. The compound is a combination of piper dine and N-aminoethylpiperazine. These compounds are superior to the DETA series in impact strength and durability. The high impact resistance of cycloaliphatic amine epoxy makes it a suitable choice for applications where durability is crucial.
