Product Description
EPOCAST® 50-A1 Resin with Hardener 9816 is a two-component epoxy material system comprising EPOCAST® 50-A1 epoxy resin and Hardener 9816. The resin is supplied as an epoxy constituent with a reported dynamic viscosity of 7,770 mPa·s at 20°C and density of 1.2 g/cm³ at 25°C. Hardener 9816 is a lower-viscosity curing component with a reported dynamic viscosity of 250 mPa·s and density of 1.02 g/cm³ at 25°C. The supplied resources do not establish the mix ratio, working life, cure schedule, supported substrates, applications, or cured performance of the combined system.
Key features
- Two-component epoxy system: Combines EPOCAST® 50-A1 epoxy resin with Hardener 9816 as separate resin and curing components.
- Resin viscosity: EPOCAST® 50-A1 has a reported dynamic viscosity of 7,770 mPa·s at 20°C.
- Low-viscosity hardener: Hardener 9816 has a reported dynamic viscosity of 250 mPa·s at 25°C.
