What is West System epoxy used for?

Based on 105 Epoxy Resin, WEST SYSTEM Epoxy is a versatile low-viscosity epoxy system. It is used for boat building, composite construction and repairs that require high-strength, waterproof coating, bonding, and filling.

How do you use 105 epoxy resin?

Using gel coat over WEST SYSTEM 105 Epoxy Resin and Hardener

  1. Mix your epoxy resin and hardener at the proper ratio (Mini Pumps make this a snap).
  2. Allow the epoxy to fully cured.
  3. Before applying gel coat, remove any amine blush from the cured epoxy surface.

How long does it take for West System epoxy to cure?

6-8 hours
#205 Fast Hardener, mixed at a 5:1 ratio with #105 Resin, results in a pot life of 9-12 minutes at 72°F, with solid cure in 6-8 hours.

How thick can I pour West System epoxy?

While it is a slower curing system, it still should not be poured more than ¼” deep at a time. We have found that building up castings ¼” at a time allows the epoxy to cure without overheating.

Is epoxy resin permanent?

Epoxy glue is long-lasting, designed to create permanent bonding. So naturally, it’s not the easiest substance to remove so you should take care when applying the epoxy adhesive. Removing uncured epoxy is very simple.

Why is epoxy not hardening?

If your epoxy resin hasn’t cured properly, this means that the chemical reaction between the resin and hardener was not able to take place. Sticky resin is typically caused by inaccurate measuring or under mixing. Try moving your piece to a warmer spot: if it doesn’t dry, re-pour with a fresh coat of resin.

Will epoxy crack in cold weather?

While epoxy coatings themselves do not crack in extreme heat or cold, concrete does. Epoxy coatings cannot withstand the stresses associated with concrete cracks due to settling, dry shrinkage or other factors.

What do you need to know about West system 105 epoxy?

WEST SYSTEM 105 Epoxy Resin, Hardeners, Fillers, Additives, Reinforcing Materials, Dispensing Pumps and Application Tools were designed and developed with the end-user in mind. Start with the Product Selection Guide to determine which products you need for your specific project.

What does 105 epoxy resin do for wood?

105 Epoxy Resin is a clear, light amber, low-viscosity liquid epoxy resin formulated specifically to wet out and bond with wood, fiberglass and a variety of metals. Multiple coats of a 105 Epoxy Resin create a superior moisture barrier and a tough, stable base for paints and varnishes.

Is it safe to use epoxy with West system fillers?

Unlike polyester or vinylester resins, our epoxy virtually does not shrink after curing. With a relatively high flash point and no solvent odor, it’s safer to use than styrenated resins. Modifying this epoxy with WEST SYSTEM fillers creates an excellent structural adhesive or fairing compound.

Can you use gel coat over West system 105 resin?

WEST SYSTEM 105 Resin/207 Special Clear Hardener does not blush. Gel coat manufacturers shy away from approving the use of non-air inhibited gel coat over epoxy because they’re concerned amine blush will interfere with the gel coat’s cure. All you need to do to remove the blush is wash the surface with plain water.
