Taiwan South Asia Epoxy Resin NPES-909
South Asia NPES-909 is a high molecular weight solid epoxy resin of bisphenol A type, mainly used in canned coatings and coil steel coatings. The core technical parameters are as follows:
Core physical and chemical indicators
Appearance: Slightly yellow to yellow flaky solid
Epoxy Equivalent (EEW): 1800-2500 g/eq (some data subdivision standards are 1800-2400 g/eq)
Softening point (R&B): 130-150 ℃
Gardner hue: ≤ 1.0 Max
Dissolved viscosity: A 40% solution of butyl carbitol is prepared, with a viscosity of approximately Z3-Z5 (or corresponding range of 2300-10000 mPa · s, depending on the test solvent and concentration) at 25 ℃
Chlorine content (HyCl): usually ≤ 500 ppm
CAS number: 61788-97-4
Performance characteristics and applications
Curing characteristics: After high-temperature curing with amino resin or phenolic formaldehyde resin, it has high cross-linking density
Main performance: excellent chemical resistance, hardness, flexibility, and adhesion properties
Typical applications: specialized for canned coatings, coil coatings, and rust proof primers
Note: There may be slight differences in the parameters of different batches or specific sub grades (such as NPES-909H, whose epoxy equivalent is usually 2100-2500 g/eq and softening point is 135-150 ℃). Please refer to the latest TDS provided by the supplier for actual production.
