Methyltetrahydrophthalic Anhydride (MTHPA), identified by CAS number 26590-20-5, is a chemical compound that plays a crucial role in various industrial applications, particularly as a curing agent for epoxy resins. For R&D scientists and product formulators, understanding its properties and procurement nuances is essential for successful product development. As a leading chemical manufacturer and supplier, we aim to provide clarity on MTHPA and facilitate your purchasing decisions.

MTHPA is an unsaturated cyclic anhydride, a derivative of phthalic anhydride, known for its unique chemical structure that enables effective cross-linking reactions with epoxy resins. Key properties include its appearance as a slightly yellow liquid, a specific anhydride content (typically above 41.0%), low volatile content, and a low freezing point (below -15℃). These characteristics make it a preferred choice for applications requiring high performance and ease of handling.

The versatility of MTHPA is evident in its wide range of applications. Primarily, it serves as an excellent curing agent for epoxy resins, contributing to materials with superior mechanical strength, thermal stability, and chemical resistance. This makes it invaluable in the manufacturing of solvent-free paints, durable adhesives, and robust laminated boards. Furthermore, MTHPA is a cornerstone ingredient in high-voltage electrical apparatus, including capacitors, transformers, and switchgears, due to its outstanding electrical insulating properties.

When considering the purchase of MTHPA, several factors are important for B2B clients. Firstly, sourcing from a reputable manufacturer in China ensures competitive pricing and a stable supply chain. We, as a dedicated supplier, offer MTHPA that meets strict quality specifications and provide necessary documentation such as COAs and MSDSs. Secondly, understanding the packaging and storage requirements – typically in 25kg or 220kg drums, stored in cool, dry places – is vital for maintaining product integrity.
