Hardener 205 is used in most situations to achieve a fast cure that produces an epoxy with rapid physical properties.
It is useful for bonding, and at lower temperatures.
When mixed with 105 resin, at a ratio of 5:1 (resin:hardener), the cured resin/hardener mixture produces a rigid, high-strength solid with excellent cohesive properties and outstanding water vapor barrier with excellent bonding and coating properties.
Pot life at 25°C: 10 to 15 minutes
Cure to solid at 21°C: 5 to 7 hours
Curing to full strength at 21°C: 5 to 7 days
Minimum recommended working temperature: 5°C
Dosing: The mini-pumps allow you to pour the exact proportions of resin and hardener. In order to have the correct proportions, it is sufficient to make one pressure of resin for one pressure of hardener.
Mixing: Mix the resin and hardener for two minutes or longer at low temperatures. Scrape down the sides and bottom of the pot when mixing.
Consumption :
- for a 1kg mixture on a porous surface at 25°C: 6.5 - 7.5 m².
- for a 1kg mixture on a non-porous surface at 25°C : 8.5 - 9.5 m².
