Methyl Tetrahydrophthalic Anhydride (MTHPA) 11070-44-3
Category : Catalyst and Auxiliary/Other Auxiliary Agent
CAS NO : 11070-44-3 EC NO : 234-290-7;251-823-9 MF : C9H10O3 MW : 166.1766 Specification : light yellow transparent liquid Packing : 20 kilograms, 25 kg, 220 kg and 240 kg IBC barrel packaging Product description : 1.Light color, pre-addition 0.5-3% tertiary amine accelerator (BDM A, DMP-30) basically unchanged. It is a light yellow transparent liquid, which can be used to cast light or natural solids. 2. Low viscosity: the process of casting, sealing and impregnation is good. A large number of fillers can be added when casting to make the curing material perform well. When used for impregnation, it is easy to adjust it into suitable impregnation conditions. Laminaring is conducive to the affinity of the basics. 3. Stable performance, low freezing point, long application period, can be stored for a long time at room temperature, which is convenient for pipeline transportation. It is conducive to production automation and adapts to cold areas. 4. Low volatility, small heating loss, low toxicity, and only amine curing agents1/20~1/40.less irritating to human eyes and skin. 5. Good mutual solubility. This product is mutually soluble with all epoxy resins, and the mixing viscosity is low.At the same time, the contraction and exothermic effect of the system are relatively low when heated and curing.Main uses： 6.Small heating loss, small volume shrinkage of curing, high thermal deformation temperature, excellent mechanical and electrical properties, and small dielectric loss angle tangent(110℃). Uses : It is used as epoxy resin curing agent, widely used in electronic components, LED digital tube filling glue, FRP composite wind power blades, automotive parts, dry transformers, high-voltage switches, high-voltage capacitors, transformers, household app Synonyms : tetrahydromethylphthalic anhydride;Tetrahydromethyl-1,3-isobenzofurandione;4-Methyl tetrahydro phthalic anhydride;1,3-Isobenzofurandione, tetrahydromethyl;3a-methyl-3a,4,5,6-tetrahydro-2-benzofuran-1,3-dione;7a-methyl-3a,4,5,7a-tetrahydro-2-benzofuran-1,3-dione;1,3-Isobenzofurandione, tetrahydromethyl-;cis-4-Methyl-1,2,3,6-tetrahydrophthalic anhydride;4-Methyl Tetrahydrophthalic Anhydride;4-Methylcyclohexane-1,2-dicarboxylic anhydride;5-methyl-4,5,6,7-tetrahydro-2-benzofuran-1,3-dione;6-methyl-3a,4,5,7a-tetrahydro-2-benzofuran-1,3-dione;4-Methylhexahydrophthalic anhydride;MeH-HPA;MTHPA;Methyl tetrahydrophthalic anhydride;Methyltetrahydrophthalic anhydride;Methy tetra-Hydro Phthalic Anhydride;Methyltetrahydrophthalicanhydride;Methyl tetrahydro phthalic anhydride; Molecular Structure :
