Product details


The 2-component epoxy resin complete set consists of the 105 resin and a 205 hardener as well as the accessories required for direct processing: 301-5A pump set, 2 pairs of disposable gloves, 6x 60 ml mixing cups, 3x mixing sticks.

The epoxy system has high strength and outstanding versatility, making it suitable for a wide variety of work and repairs on board. The system is also a good choice for domestic use and other building projects. In addition, the 2-component system is suitable for a wide variety of substrates such as wood, GRP or various metals.
Hardener 205 is used when a particularly fast hardening of the resin is required. WEST SYSTEM Fast Hardener 205 is the best choice in cold weather, as it ensures good hardening even at temperatures as low as +5 °C. When mixed with Resin 105 at a ratio of 5 parts resin to 1 part hardener, the cured mixture produces a high-strength, rigid body with very good cohesive properties and excellent moisture vapour tightness. For an optimal mixing ratio it is recommended to use the West System 300 Mini pumps. One full stroke of resin and hardener gives the right mixing ratio. Pot life: 9 - 12 minutes at 22°C. Hardens to a solid mass in five to seven hours at 22°C. Full hardening after several days.

Possible applications:
  • Bonding
  • Joining of fillets
  • Fastening fittings and casting foundations for fittings
  • Fastening of bolts
  • Laminating and laminating
  • Filling
  • Laminating with glass fabric
  • Barrier coating

Substrates:
  • Wood
  • glass fibre
  • Composite materials
  • Various metals

Addition of fillers

WEST SYSTEM offers a range of fillers that are used to thicken the basic mixture of resin and hardener for specific applications. By adding an appropriate amount of filler, a "thicker" consistency can be achieved (suitable for filling blowholes, filler grooves, for producing large, uneven bonds and for use as a levelling compound).

Use at cold temperatures

Even when using Schneller 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 resin and hardener containers, e.g. by placing them 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.

Hardener overview
Hardener Use of resin/hardener Minimum temperature Pot life at 22 °C (100g) Processing time at 22 °C (thin layer) Curing time at 22 °C (thin layer)
205 Fast hardener General bonding and coating 5 °C 9-12 minutes 60-70 minutes 6-8 hours
206 Slow hardener General bonding and coating 16 °C 20-25 minutes 90-110 minutes 10-15 hours
Note: Epoxy resin cures faster at higher temperatures and when applying thicker layers

Works as described
The material comes with very detailed instructions and extensive safety information. It is highly recommended to read the instructions completely. They also include processing variations for all possible applications. The instructions were extremely helpful to me. The resin mixture is very easy to work with. I can't give precise information about the drying time, as I was laminating in an unheated basement at approximately 12°C. At this temperature, the resin remains workable for about 45 minutes.
