it's not for a boat. But for the manufacture of an airplane used with dosing pumps, this resin contributes to the bonding and internal protection of the formwork on the wings of my plane. It's a Pitts model 12 intended for aerobatics.

Product details

This 2-part epoxy resin set consists of the 105 Epoxy Resin and 206 Slow Hardener. The professional epoxy system was developed specifically for the boating sector. It has high strength and outstanding versatility, making it suitable for a wide range of work and repairs on your boat. The system is also highly suitable for domestic use and other DIY projects. It can be used on a variety of surfaces such as wood, GRP or metals.
206 Slow hardener is an epoxy hardener, which consists of a low viscosity mixture of polyamines. It can be mixed with the 105 Epoxy resin in the ratio of 5 parts resin to 1 part hardener, the cured mixture yields a rigid, high-strength, moisture-resistant solid body with excellent bonding and barrier coating properties, perfectly suited as a coating or adhesive and for wetting out fiberglass. For an optimal mixing ratio, it is recommended to use the West System 300 Mini pumps. One whole pump of the resin and hardener yields the correct mixing ratio.
The hardener is typically used for larger areas and bondings that take a longer time. Pot life at 22°C: 25 - 30 minutes. Hardens to a solid mass in about 10 hours at 22°C and reaches full hardening after about nine days.

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

Adding fillers
WEST SYSTEM offers a range of fillers that are used to thicken the base mix of resin and hardener for specific applications. By adding filler, a "thicker" consistency can be achieved (suitable for filling cavities, fillets, making large, uneven bondings and for use as a filler).

Hardener overview

Hardener	Resin/hardener use	Minimum temp	Pot life at 22 °C (100g)	Processing time at 22 °C (thin film)	Curing time at 22 °C (thin film)
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 cures faster at higher temperatures and when thicker layers are applied.

Good but expensive

The product is really good, but there are comparable resins on the market for a third of the price. And if you only want to mix small quantities, the savings could even cover a €10 postal scale. Then you wouldn't have to clean the pumps anymore either.

Sorry, but it's true.
