Methyl hexahydrophthalic anhydride
Ι. 3,4-Methyl hexahydrophthalic anhydride Abb: MHHPA CAS RN: 25550-51-0 Molecular Formula: C9H12O3 Molecular Weight: 168.19 Specific Gravity: 1.162 Structural Formula: Soluble in benzene and propanone, etc., with hydroscopic property. Quality index: Appearance colorless transparent liquid Color(Pt-Co) <5# Iodine Value <1% Free acid <0.5% Acid value (mgKOH/g) >645 ΙΙ. Hexahydro-4-methylphthalic anhydride Abb: 4-MHHPA CAS RN: 19438-60-9 Molecular Formula: C9H12O3 Molecular Weight: 168.19 Specific Gravity: 1.162 Structural Formula: Soluble in benzene and propanone, etc., with hydroscopic property. Quality index: Appearance Colorless clear liquid Content ≥98% Features: Methyl hexahydrophthalic anhydride is produced from methyl tetrahydrophthalic anhydride by catalytic hydrogenation. It is a high-performance product among acid anhydride-type solidifying agent, not only has the typical performances as methyl tetrahydrophthalic anhydride: high purity, light color liquid, low viscosity, low volatility, low toxicity, low heating loss, stable performances, long use life, low freezing point, and can be stored for a long time under room temperature; but also has more excellent performances than that of methyl tetrahydrophthalic anhydride: colorless, transparent, basically unchange color after being added accelerant and epoxyl solidified substance appears white; good resistance to heat, especially under the temperature lower than 150°C, epoxyl solidified substance are of excellent mechanical and electric properties, excellent weatherability, not be affected by light and heat, good moisture resistance, high reaction activity, fast solidifying speed and short gelation time. Uses: 1.as solidifying agent for epoxy resins: MHHPA is heating-solidification type acid anhydride solidifying agent, mainly used in electrical and electronic field, with low melting point, the compounding matter with alicyclic epoxy resin is of low viscosity, long use life, excellent heat resistance and high-temperature electric properties, can be used in dipping of coil of electric apparatus, casting of electric parts and sealing of semiconductor. 2.as adhesive: the alicyclic epoxy adhesive made from MHHPA has similar refractive index as optical glass, low internal stress after solidifying, high adhesion strength, color unchangeable, resistance to aging, applicable for cohering large-area optical parts. 3.as insecticide, plasticizer and antirust, etc. Storage, Packing & Transportation: 25kg plastic drum or 220kg metal pail,Avoid moisture, fire and water. Kept in dry and ventilating place. |
