Light Colored Cycloaliphatic Amine Hardener Transparent Low-Viscosity Modified 8219
light-colored transparent low-viscosity modified cycloaliphatic amine epoxy resin hardener 8219
Epoxy hardener 8219 a modified cycloaliphatic polyamine curing agent intended for ambient is a modified cycloaliphatic polyamine curing agent intended for ambient curing of liquid epoxy resin. It has low viscosity and good acid and chemical resistance. Epoxy resin systems cured with 8219 at temperatures above 10 °C show tack-free and colorfast surfaces. It has an outstanding early water resistance.curing of liquid epoxy resin. It has low viscosity and good acid and chemical resistance.
Epoxy resin systems cured with DEH 488 at temperatures above 10 °C show tack-free
Advantages
• Low viscosity
• High reactivity
• Not manufactured with nonylphenol
and colorfast surfaces. D.E.H. 488 has an outstanding early water resistance.
