Close menu Product information "West System Resin Hardener" West System 105-205 (fast hardener): Resin: 105 Epoxy resin Hardener: 205 Fast Hardener Curing time: Fast Working time: Approx. 9-12 minutes at 20°C Curing time: 6-8 hours at 20°C for functional hardness, full hardness after approx. 5-7 days Application: Ideal for lower temperature applications or when fast curing is required. Particularly useful for repairs and projects where it is important to be able to continue working quickly. Choosing the right set: The decision between the fast hardener 105-205 and the slow hardener 105-206 depends on various factors: Temperature: at lower temperatures the 205 fast hardener is more advantageous, while at higher temperatures the 206 slow hardener is more suitable. Project size: For larger projects where more time is needed for processing, the 206 slow hardener is more suitable. Schedule: If the job needs to be completed quickly, the 205 fast hardener is the right choice. Both systems are flexible and offer high performance, so the choice depends mainly on the specific requirements of your project. Similarities: Resin: Both systems use the same 105 epoxy resin, which is known for its clarity, strength and versatility. Mixing Ratio: Both systems are mixed at the same ratio (resin to hardener), typically 5:1 by volume. Uses: Both sets can be used for a variety of applications in boat building, woodworking, composites and other DIY projects.
