WEST SYSTEM
#206 Slow Hardener

206 Slow Hardener is a low-viscosity epoxy curing agent for use when extended working and cure time is needed or to provide adequate working time at higher temperatures. When combined with 105 Resin in a five-part resin to one-part hardener ratio, the cured resin/hardener mixture yields a rigid, high-strength, moisture-resistant solid with excellent bonding and coating properties. Not intended for clear coating.

Use a pump kit, sold separately to mix WEST SYSTEM #105 Resin and hardeners in the correct proportions. For hardeners #205 (Fast) and #206 (Slow) in Group Sizes A, B and C, select the #300 Mini Pump Kit, Model 3405669. For larger group sizes of #205 and #206, use the “Model A” #306-25, Model 335703.

    West System epoxy is really great to use. I use it in general applications for marine repairs and for boatbuilding. West works very well.

          I increased the hardener/resin ratio (more hardener) when working below 60 degrees ambient. It usually took overnight for my repair to completely cure. I've had very good success with this product.

          Product was bought at a West Marine store.

                I used West System 206/105/422 to seal my bottom after taking it down to clean fiberglass. The removal of material left low spots which I added colloidal to the mix for and it faired beautifully and hard as a rock.

                      Great stuff. Extremely predictable curing rate. Brush or roll a coat on lightly sanded wood, allow to cure overnight, and, the surface is ready for paint or a second coat if desired.

                        206 allows me time to get everything clamped up perfectly and also allows me time when the temperatures get a bit warmer in our hot Texas summer. Using the pumps takes all the guess work out of making a perfect mix every time.
