Product Applications
Epoxy Resin Curing Agent: It is widely used in epoxy resin systems, which can endow epoxy resins with good mechanical properties, electrical properties, and chemical corrosion resistance. It is commonly used in the manufacture of electronic components, electrical insulating materials, coatings, adhesives, etc. When mixed with epoxy resins, the curing reaction rate is moderate, and the operability is good. The cured product has high hardness and heat resistance.
Modifier for Polyester Resin: In the production of polyester resins, the addition of 3 - Methyltetrahydrophthalic anhydride can improve the performance of polyester resins, such as enhancing their flexibility, weather resistance, and gloss. It can be used to manufacture various polyester plastic products, such as films, sheets, fibers, etc.
Other Fields: It can also be used to prepare plasticizers, surfactants, pesticide intermediates, and other fine chemicals. In some special chemical reactions, it participates in the reaction as an acid anhydride - type reagent to introduce specific functional groups, thereby synthesizing organic compounds with special properties.
Product Specifications
Purity: The purity of general industrial - grade products can reach over 95%, and that of high - purity products can reach 99% and above, which is used in fields with high - purity requirements, such as electronics and aerospace.
Acid Value: Usually within a specific range, such as 450 - 500 mgKOH/g. The acid value affects its reaction activity and curing performance with epoxy resins and other substances.
Color: Generally, a light color is required, usually expressed by the platinum - cobalt colorimetric method, such as not exceeding 50 color numbers, to ensure that it will not have an adverse effect on the appearance of the product during application.
Packaging and Storage
Packaging: It is usually packaged in plastic drums or iron drums. The net content of each drum is generally 25kg, 50kg, 200kg, etc. Packaging specifications can also be customized according to customer requirements.
Storage: It should be stored in a cool, dry, and well - ventilated warehouse, away from fire sources and heat sources. Avoid contact with strong oxidants, strong alkalis, and other substances to prevent chemical reactions. The recommended storage temperature is generally 5 - 35ºC. Avoid high or low temperatures that may affect the product performance.
Safety Information
Toxicity: It is toxic to a certain extent and has a stimulating effect on the skin, eyes, and respiratory tract. Inhaling its vapor or dust may cause respiratory irritation, headache, nausea, and other symptoms.
Safe Operation: Operators should wear protective glasses, gloves, masks, and other protective equipment during use to avoid skin contact and inhalation. In case of contact with skin or eyes, rinse immediately with a large amount of clean water and seek medical attention in a timely manner. Use it in a well - ventilated environment and avoid long - term exposure to this substance in a confined space.
