It refers to materials that are added to a base material to increase its various properties such as hardness, strength, durability, etc. Hardeners are used in various industries, especially in the production of polymer materials, resins, paints and chemicals.
Hardener is added to the resin as an additional substance in resin production to start the polymerization or hardening process of the resin. In the paint industry, hardener can be added to the paint to improve the durability and hardness properties of the paint.
If we call the resin group A and it is a type that does not dry by itself in a short time, then we need a material from group B, which is the hardener, for the resin curing process.
Epoxy Hardener is a chemical substance that is used in the curing process of epoxy resin to harden and strengthen the resin. Epoxy resin alone is a liquid and soft material, and epoxy hardener gives it the power to harden and deform.
Epoxy hardener is also known as curing agent. When epoxy hardener is added to epoxy resin, a chemical reaction called polymerization occurs. This reaction is initiated by the hardener and leads to the formation of polymer and network links in the molecular structure of the resin. This process leads to strengthening, hardening and forming a hard and resistant structure in the end.
The type of epoxy hardener is usually determined by application requirements and operating temperature range. Some common types of epoxy hardeners include amine hardeners (such as amine ethylene diamine, amine triisocyanate, and aromatic amine) and epoxy hardeners (such as bisphenol epoxide).
This chemical composition is classified into different types according to the application of epoxy hardener or reactive agent. Its 10% theta type is among the aliphatic amino chemical compounds, which has a very fast cooking speed. This combination is usually used in composite industries, shoe molding, adhesive production, stone making, flooring, and tank lining.
Another type is used as a hardener and added to epoxy resin to increase its strength. Among its most important applications, we can mention the construction of platforms, flooring used in corrosive environments, and the construction of transmission pipes.
It is very important to buy transparent and quality hardener. The following are the most important advantages of this chemical composition.
– High resistance to heat
– Resistance in environments where chemical activity is carried out.
– Appropriate viscosity
– Ideal mechanical resistance in the long term
– Applicability in oil places
– Excellent adhesion to resin materials
Considering the important features of quality epoxy hardener, if the quality of this chemical compound decreases, its properties will also decrease and lead to product damage in various industries.
To ensure the quality of this chemical composition, it is better to buy it from reputable companies. One of the most reliable hardener sales centres is “ShimiAfsoon”, which can provide you with this product with the best quality.
“ShimiAfsoon” is a manufacturer of quality epoxy hardener in Iran. To buy this chemical compound, it is enough to contact our colleagues and place your order through the communication channels specified on the site.
The selling price of epoxy hardener and polyester hardener is different according to the types of hardener. On the other hand, you can buy it in half kilo, 1 kilo, 5 and 18 kilo packages. Also, for bulk purchase, you can buy this chemical compound in the form of 200 kilos (in a barrel). For this reason, its final price depends on the type and volume of compounds you buy.
Q: Can hardener be used without resin?
A: Both resin and hardener remain liquid if used without each other. So you need a hardener for the resin curing process.
Q: Is thinner the same as hardener?
A: No; Hardeners and thinners are substances that work against each other. Hardener is a substance that is added to harden another substance such as paint or varnish. Thinner is a volatile liquid that is useful for thinning paint.
Q: What happens if we pour too much hardener into the resin?
A: The ratio must be maintained in the combination of resin and hardener. One of the reasons that cause the failure of the work result is the incorrectness and non-observance of the ratio of the mixture. If too much hardener is poured, the chemical reaction will change and the resin curing process will not work properly.
Q: Why is my resin still bending after 24 hours?
A: In most cases if everything is correct in the resin and hardener combination and you have done all the conditions correctly, this problem is because the resin needs more than 24 hours to cure. Usually, in 24 hours, the resin is 95% hardened, and during this time, you can shape and bend your resin if you need. Therefore, you should wait more than 24 hours for the resin curing process to complete and finalize.
