The slow hardener 206 is an epoxy hardener, which consists of a low viscosity mixture of polyamines. It can be mixed with the resin 105 in he ratio of 5 parts resin to 1 part hardener, the cured mixture yields a high strength, rigid, moisture-resistant body that is perfectly suited as a coating or adhesive and for wetting of glass fabric.The hardener 206 is typically used for larger areas and bondings that take a longer time. Pot life at 21°C: 25 to 30 minutes. Cured at 21°C in about 9 hours into a solid mass, and reaches full cure in about nine days.
