Curing agents, also known as hardeners, are essential components of many polymer systems, including Epoxy Resins. Curing agents react with the epoxy resin to form a three-dimensional crosslinked network, resulting in a cured polymer with improved mechanical properties, chemical resistance, and thermal stability.

There are many kinds of artificial stone, causing great differences in price. The following is a detailed introduction of artificial stone with different materials:
Composite artificial acrylic artificial stone countertops The practical artificial stone between the resin plate and the pure acrylic plate has a higher finish and a better handle than the standard resin artificial stone.
Due to the relatively moderate prices and strong practicality, it is widely recognized by consumers and its shipments in the market are still quite large.
Calcium carbonate artificial stone countertops pure acrylic artificial stone countertops bright, not yellow, not easy to crack, heat, collision resistance. From the viewpoint of the content of artificial stone, the composition of acrylic only accounts for 40%, and the other 60% is occupied by aluminum hydroxide, resin and pigment.
Due to the high technical and equipment requirements of the manufacturer and the higher raw material costs than other products, the market price has remained high.
Most of the artificial stone products on the artificial stone countertops in the resin board market fall into this category. As the manufacturer's production scale, technology, processes, equipment, etc., vary greatly, the quality of the raw materials used has not been equal, resulting in high or low product costs, directly affecting the product's price and quality.
There are several types of curing agents, each with its own unique properties and applications. The most common type is amine-based curing agents, which react with the epoxy functional group to form a secondary amine and an alcohol. This reaction is exothermic and can be accelerated by heat, making it ideal for high-temperature applications.
Another type of curing agent is anhydride-based, which react with the epoxy group to form a cyclic acid anhydride and a hydroxyl group. These curing agents are typically used in applications where water resistance is critical, such as marine coatings and adhesives.
Other types of curing agents include phenolic, acid, and catalytic curing agents. Phenolic curing agents are used in high-temperature applications, while acid curing agents are used in low-temperature applications. Catalytic curing agents are used to accelerate the curing process and are typically used in combination with other curing agents.
The choice of curing agent depends on the specific application requirements, such as cure time, cure temperature, and final properties of the cured polymer. It is important to choose the correct curing agent to ensure that the final product meets the desired specifications.
In summary, curing agents are essential components of many polymer systems, including epoxy resins, and play a critical role in improving the mechanical, chemical, and thermal properties of the cured polymer. The choice of curing agent depends on the specific application requirements and must be carefully considered to ensure the final product meets the desired specifications.
Artificial stone types and prices
Artificial stone countertops are currently the main materials used in the kitchen countertops in the decoration market, and most households will use them, so artificial stone countertops are also attracting attention. The price of artificial stone varies according to the type of artificial stone.
