General Description

West System 105 (formally Z105) epoxy resin is the base material on which all West System compounds are built. West System epoxies are used extensively in the marine industry and are based on a 5:1 ratio (5 parts resin to 1 part hardener).

The unique characteristics of West System epoxy resin make it ideal for sealing, laminating, coating and bonding of various products. It has been designed specifically to wet out and bond with wood fibre, fibreglass, reinforcing fabrics and a variety of metals when mixed at the proper ratio. Users can also control the resins curing or working time by selecting a specific hardener.

An excellent adhesive, 105 epoxy resin will bridge gaps and fill voids when modified with West System fillers which can be sanded and shaped when cured. With roller applications, it has excellent thin-film characteristics to flow out and self-level without "fisheyeing."

West System Pump Dispensers are also available.

Please Note: This is a laminating resin, designed for brushing over in thin layers. It is not a casting or bench top resin, trying to use this product for that purpose will cause bubbles. For casting/bench top, please check the respective categories available on our home page.

West System

First time doing fibreglassing so a bit of uncertainty as well as trial and error starting to use products. Found that the 205 works a bit faster than I had anticipated even though temperature has dropped here recently, so a bit of learning for me. Been good that I have had a few simple filling jobs just to get used to things/experiment a bit first before getting onto a bigger glassing project soon. Second go at things was better than the first and kept getting better! West System isn't as easy to access up where I live, so have to travel to get things and definitely a lot more expensive in places that do stock product. Getting things from you guys was easy and heaps cheaper. On hindsight, probably would have been good to have a bit of a chat to someone first about ideas, but no real problems so far, just finding out how quick the stuff sets and how hot it can get! Biggest hassle has been going through a couple of measuring cups too quickly. In the end, though, you just have to get in and do things to learn.

Only having one other product to compare to this has been top notch. Does what it says on the box without issue. Pumps are great too, no mess no fuss!
