Good evening, depending on what type of curing you are going to do and what the end groups of your resin are involved in the reaction. Aliphatic cycloamines are generally preferred as epoxy resins, and can also be used to cure acrylic resins, modified alkyd resins, etc. In addition to the fact that polyurethane is NCO-capped and cannot be cured with amine groups (of course, if you have the ability, you can also modify it), almost all modifications except polyurethane and anhydride can be bridged with aliphatic amines.

Leaking one, there is also unsaturated resin, and this aliphatic amine also works very well. Because the active group released by many curing agents is fixed, and the resin can be modified freely, it is difficult to say 100% in one sentence whether it can be used or not, such as isocyanate, change the end, acrylic acid and alkyd can be used, such as the current bridge paint and mechanical paint. The specific problems are re-analyzed in detail.

The epoxy resin curing agent is made of phenol, formaldehyde, ethylenediamine, p-tert-butylphenol, n-butanol glycidyl ether, polypropylene glycidyl ether and other raw material components.

Epoxy curing agents are used as epoxy resin-based adhesives in the field of material technology. Provide epoxy resin curing agent with special properties under special conditions such as low temperature and underwater.

It is characterized by the ratio of raw materials such as phenol, formaldehyde, ethylenediamine, p-tert-butylphenol, n-butanol glycidyl ether, polypropylene glycidyl ether and other raw materials. It is better than general curing agent, and has positive effects such as low temperature curing, water curing, fast curing, oil resistance, flame resistance, good toughness, and easy to use.

Under the change of the ratio of the two proportions, add more curing (50% 100%) agents appropriately. Mix thoroughly, and it can also be warmed during curing (if the electronic components are not damaged).

4. Low shrinkage and good stability. It can make the epoxy resin system have outstanding dimensional stability and durability.

5. Strong mechanical properties, surface leakage resistance, arc resistance.

Curing agent, commonly known as hardener, curing agent or metastabilizer, is a class of substances or mixtures that enhance or control the curing reaction. While it improves the hardness of the ground, it can also improve its wear resistance and waterproofing effects. What are the classifications of curing agents?

What is the function of an epoxy curing agent? Let's learn about the classification of epoxy resin curing agents and the number of reputation roles of epoxy resin curing agents.

Epoxy resin curing agent.

1. Classification of epoxy resin curing agent.

1. Classification by use.

Curing agents can be divided into room temperature curing agents and heating curing agents according to their uses. The difference between the two is that the room temperature curing agent is suitable for fields without heating process, while the high temperature curing agent can release the isocyanate group during heat treatment and react with the hydroxyl group and other groups on the molecular chain of the water-based resin to form a cross-linked structure, which can significantly improve the performance of the water-based resin.

2. Classified according to chemical composition.

According to the classification of chemical composition, it can be divided into aliphatic amines, aromatic amines, amide amines, latent curing amines, and urea substitutes. These types vary depending on the chemical composition in the field of use.

Epoxy resin curing agent construction.

Second, the role of epoxy resin curing agent.

The performance of epoxy resin curing at high temperature is relatively good, but it is difficult to use materials such as coatings in the construction industry when heating, so it needs to be cured at room temperature, and the effect of epoxy resin curing agent is particularly obvious. Epoxy resin curing agent is widely used in electronics, electrical appliances and other aspects.

In the classification of epoxy resin curing agents, aliphatic polyamine cures have excellent adhesion, alkali and water resistance, and aromatic polyamines are also excellent in terms of product resistance. Since the nitrogen element in the curing agent component forms hydrogen bonds with the metal, it also has an excellent anti-rust effect.

The role of epoxy resin curing agent.

The above is the classification of epoxy resin curing agent and the role of epoxy resin curing agent for you to share or enjoy, I hope it will help you. If you want to know more about the void cavity of epoxy resin curing agent, please stay tuned.

Summary. For example, epoxy resin curing agents include organic amines, organic anhydrides, imidazoles, polymers and other modified varieties. Acrylic curing agents have a redox system composed of organic peroxides and organic nitrides; Unsaturated polyester resins use organic peroxides and metal salts; Rubber viscosity uses various vulcanizing agents (such as metal oxides, sulfur), etc.; Others are cured by moisture in the air, such as room-temperature curing silicone rubber sealants, certain polyurethane adhesives and cyanoacrylate adhesives.

In short, there are many types of curing agents, which should be treated and selected separately under specific conditions.

The concept of curing agent: Curing agent, also known as hardener, curing agent or setting agent, is a class of substances or mixtures that enhance or control the curing reaction. Resin curing is a chemical reaction such as condensation, closed loop, addition or catalysis, so that the thermosetting resin undergoes an irreversible and rapid transformation process, and the curing is completed by adding a curing (crosslinking) agent.

Curing agent is an indispensable additive, whether it is used as a binder, coating, castable, it is necessary to add a curing agent, otherwise epoxy resin can not be cured. The variety of curing agent has a great impact on the mechanical properties, heat resistance, water resistance, corrosion resistance and so on of the cured object.

Commonly used types of curing agents:1Curing agents can be divided into room temperature curing agents and heating curing agents according to their uses.

Epoxy resins generally have excellent performance when cured at high temperatures, but coatings and adhesives used in civil engineering and construction need to be cured at room temperature due to difficult heating. Therefore, most of them use aliphatic amines, aliphatic cyclases and polyamides, especially the coatings and adhesives used in winter have to be used in combination with polyisocyanates, or polyliuols with foul odors. 2.Medium-temperature curing agents and high-temperature curing agents are selected based on the heat resistance of the substrate and the heat resistance, adhesion, and chemical resistance of the cured object.

The focus is on polyamines and anhydrides. Due to the excellent electrical properties of anhydride cured products, the group chain is widely used in electronics and electrical appliances. 3.

The adhesion of aliphatic polyamine solidifiers, alkali resistance, and water resistance are excellent. Aromatic polyamines are also excellent in terms of chemical resistance. Because the amino nitrogen element silver forms hydrogen bonds with metals, it has excellent anti-rust effect.

The higher the amine concentration, the better the rust prevention effect. Anhydride curing agents and epoxy resins form ester bonds, which show high resistance to organic and inorganic acids, and generally exceed polyamines in electrical properties.
