M.W.:266.38
Assay:99.5%
Boiling point: 180 ~ 182 ℃ (0.67kPa)
Refractive index: 1.477
Viscosity: (20 ℃) 590mPa · S
Application:
Used as epoxy curing agents adhesive toughness, the reference amount of 120 to 150 parts, easily mixed with epoxy resin for period of up to 3 ~ 4d. Curing conditions 100 ℃ / 2h + 150 ℃ / 2h or 85 ℃ / 2h + 150 ℃ / 20h. The cured product has a certain toughness, heat distortion temperature 66 ~ 78 ℃. Due to poor heat resistance and chemical resistance, DDSA mixed acid anhydride can be used with other. |
