WEST SYSTEM 205 Fast Hardener / 200 g
WEST SYSTEM Fast Hardener 205 / 1 kg
Hardener 205 is used when you need to have the resin cure particularly quickly. Mixed with resin 105, the cured mixture yields a rigid, high-strength, moisture-resistant solid body with excellent bonding and barrier coating properties.
Product details
Thanks to the chemically activated polyamine system, 205 Hardener ensures good curing even at 5°C. The mixture cures quickly and has a short open time in its uncured state, thus reducing the likelihood of incomplete curing due to low temperatures.
Possible applications:
- Bonding
- Filleting
- Affixing hardware and flowing out to create a base for hardware
- Fastener bonding
- Laminating
- Filling
- Laminating with fiberglass
- Barrier layering
Substrates:
- Wood
- Fiberglass
- Composites
- Various metals
Use at cold temperatures
Even when using the Faster Hardener 205, it should be noted that cold temperatures increase the viscosity of epoxy resin, making it more difficult to dose, mix and apply the mixture correctly. It is therefore advisable to preheat the containers of resin and hardener, e.g. by placing the containers under a heat lamp. Pre-warmed resins and hardeners adhere less to the mixing pumps, they are easier to mix and have better flow properties. More detailed information can be found in the technical manual.
