Basic Information and Parameters

The product is Hexahydrophthalic anhydride (hhpa) with the CAS number 13149-00-3. It is factory - supplied at a low price, which provides significant cost - effectiveness for users. Hexahydrophthalic anhydride is a white crystalline solid. Its molecular formula is C₈H₁₀O₃, and the molecular weight is approximately 154.16 g/mol. It has a relatively low melting point, usually around 32 - 34°C, and a boiling point of about 255°C. The density of hhpa is about 1.18 g/cm³. These physical properties make it suitable for a variety of industrial applications.

Uses of the Product

Hexahydrophthalic anhydride (hhpa) has a wide range of uses in different industries. In the coating industry, it is used as a curing agent for epoxy resins. When combined with epoxy resins, hhpa can significantly improve the coating's hardness, chemical resistance, and adhesion. This is particularly useful for coatings applied in harsh environments, such as industrial factories and marine vessels. In the electrical insulation field, hhpa - cured epoxy resins are used to manufacture high - performance insulation materials. These materials can effectively prevent electrical leakage and ensure the safety and reliability of electrical equipment. Additionally, hhpa is also used in the production of plastics and composites. It can enhance the mechanical properties of plastics, such as tensile strength and impact resistance, and improve the overall performance of composites.

How to Use the Product

When using Hexahydrophthalic anhydride (hhpa), certain steps and precautions should be followed. Firstly, proper personal protective equipment, such as gloves and goggles, should be worn to avoid direct contact with the skin and eyes. If it comes into contact with the skin, wash thoroughly with plenty of water. For the curing process with epoxy resins, the ratio of hhpa to epoxy resin needs to be accurately controlled according to the specific requirements of the application. Generally, the mixing ratio is determined by the equivalent ratio of the epoxy groups in the resin to the anhydride groups in hhpa. The mixture should be stirred evenly under appropriate conditions, usually at a certain temperature and for a specific period of time to ensure complete reaction. After mixing, the mixture can be applied to the target surface or used for molding operations.

Detailed Use Cases

Case 1: Marine Coating
A shipbuilding company used hhpa - cured epoxy coatings on the hull of a large - scale cargo ship. The coating had excellent resistance to seawater corrosion, preventing rust and damage to the hull. The high - hardness and adhesion properties of the coating ensured that it could withstand the impact of waves and the friction of seawater for a long time. This not only extended the service life of the ship but also reduced maintenance costs.
Case 2: Electrical Transformer Insulation
An electrical equipment manufacturer used hhpa - cured epoxy insulation materials in the production of high - voltage transformers. The insulation materials effectively reduced the risk of electrical breakdown and improved the efficiency and reliability of the transformers. The high - temperature resistance and electrical insulation properties of hhpa - cured epoxy resins ensured stable operation of the transformers under high - voltage and high - temperature conditions.
