Frequently Asked Questions

As a leading Moderate Ester Hardener RC 901 supplier, we deliver high-quality products across diverse grades to meet evolving needs, empowering global customers with safe, efficient, and compliant chemical solutions.

What are the main ingredients of Moderate Ester Hardener RC 901?

Moderate Ester Hardener RC 901 is a class of materials widely used in the industrial field. Its main components, viewed from a chemical perspective, contain specific esters. Esters occupy a central position in this hardener. These esters have delicate structures and play a key role in the hardening process. Their interaction with other substances can promote the curing reaction of the material, shaping specific physical properties and chemical stability. In addition, such hardeners may also contain auxiliary components, such as catalysts. Catalysts play a role in accelerating the reaction, making the curing reaction more efficient and rapid. It can reduce the activation energy required for the reaction, so that the reaction that may have occurred under more severe conditions can be carried out smoothly in a relatively mild environment. There may also be some additives designed to adjust the performance of the hardener. For example, to improve its fluidity, making it easier to distribute uniformly during application, thereby ensuring the uniformity of the overall properties of the material; or to enhance its storage stability, maintain good quality during storage, and extend its effective service life. All in all, the main components of Moderate Ester Hardener RC 901 are esters, with catalysts, additives, etc., working together to achieve specific functions and effects such as material hardening.

What materials is Moderate Ester Hardener RC 901 suitable for?

Moderate Ester Hardener RC 901 is suitable for a variety of materials and is used in many process fields. In the field of casting, this hard ener is suitable for sand molds with phenolic resin as a binder. Phenolic resin sand has the characteristics of high strength and low gas production, and is widely used in metal casting. Moderate Ester Hardener RC 901 is suitable for it, which can quickly harden phenolic resin sand, improve the strength and dimensional stability of sand molds, and ensure the accuracy and surface quality of castings. For example, when precision casting metal parts with complex structures, this combination allows the sand mold to reach the required strength in a short time, preventing the sand mold from deforming during pouring. In the manufacture of composite materials, it is suitable for some unsaturated polyester resin systems. Unsaturated polyester resins are low cost and have good processing properties, and are often used in the manufacture of composite products such as fiberglass. RC 901, as a hardener, can promote the cross-linking and curing of unsaturated polyester resins and improve the mechanical properties of composites. For example, when manufacturing large fiberglass reinforced plastic storage tanks, the use of this hardener can quickly cure the resin to form, improve production efficiency and ensure the structural strength of the storage tank. Furthermore, in some specialty coatings, Moderate Ester Hardener RC 901 can also play a role when the coating system contains specific ingredients that can react with ester. It promotes the cross-linking and hardening of related components in the coating, and improves the wear resistance and chemical corrosion resistance of the coating. If applied to the surface protective coating of industrial equipment, after its hardening treatment, the coating can resist harsh environmental erosion and prolong the service life of the equipment.

How long does Moderate Ester Hardener RC 901 take to cure?

Generally speaking, the curing time of ester hardeners is not a fixed value and is affected by many factors. Taking the ester-hardened alkaline phenolic resin system as an example, its curing speed depends on the activity of the organic ester. The higher the activity, the faster the curing. At the same time, factors such as the amount of curing agent added, ambient humidity, temperature, mold material, mold size, and mold exhaust will also affect the curing time. Usually, by selecting ester hardeners with different activities, the usable time can be controlled to about a few minutes to an hour, and the demolding time of the sand mold (core) will also vary due to the above factors.

What are the precautions for using Moderate Ester Hardener RC 901?

When using Moderate Ester Hardener RC 901, you need to pay attention to the following things: First, it is related to the dosage. The dosage of this agent is crucial. If the dosage is too small, the hardening will be difficult to meet expectations, the material strength will be insufficient, or it will be soft, which will be overwhelmed in practical application and damage its effectiveness. If the dosage is too much, the hardening will be too fast, the operation time will be greatly reduced, and it will be difficult to carry out the shaping, smearing and other processes when there is sufficient time, and the material may be brittle, the toughness will be lost, and the risk of fracture will easily occur. Therefore, the amount must be precisely controlled according to the material characteristics and instructions for use. Second, about the environment. Environmental temperature and humidity have a great impact. If the temperature is too low, the hardening reaction will be slow, If the temperature is higher than the appropriate range, the hardening is too fast, and it is difficult to operate finely. The same is true for humidity. If the humidity is too high, or water stains, bubbles and other defects on the surface of the material will damage its appearance and performance. Therefore, a suitable temperature and humidity environment should be selected. Generally speaking, the temperature should be 15 ° C - 35 ° C, and the humidity should be 40% - 60%. Third, pay attention to mixing. When mixing with other materials, be sure to be uniform. If the mixing is uneven, some areas will be overhardened, some will not be fully hardened, and the overall performance will be uneven, which will seriously affect the use. When mixing, use appropriate appliances, such as an electric mixer, and stir at a certain speed for a certain period of time to ensure that the ingredients are evenly integrated. Fourth This agent may contain chemical substances, which are irritating to the skin and eyes. When operating, wear protective equipment, such as gloves and goggles. If you come into contact accidentally, rinse with plenty of water immediately, and seek medical attention immediately in severe cases. Fifth, the need for storage. Storage needs to be done properly. It should be placed in a cool, dry and ventilated place, away from direct sunlight and high temperature. Improper storage, or cause it to deteriorate, affecting the hardening effect. If it exceeds the shelf life, do not use it easily. Test the performance first, and then apply it if it is qualified.

What are the advantages of Moderate Ester Hardener RC 901 compared with other similar products?

Compared with some traditional hardeners, ester hardeners usually have better environmental performance and produce less harmful gases during use.
