105 Resin is the base material of the West System family of products, on which all of the compounds are built.  The resin is a clear, pale amber, low-viscosity liquid epoxy resin.  Formulated for use with West System hardeners, it can be cured in a wide temperature range to form a high-strength solid with excellent moisture resistance.  It is designed specifically to wet out and bond with wood fiber, fiberglass, reinforcing fabrics and a variety of metals.  An excellent adhesive, 105 will fill gaps and bridge voids when modified with West System filler and can be sanded and shaped when cured.  With roller applications, it possesses excellent thin-film characteristics to flow out and self-level without “fisheyeing”.  The resin cures clear so that you can achieve a natural finish when coating with varnish.   It has a relatively high flash point and no strong solvent odor, making it safer to work with than polyesters. 105 Resin is the base material of the West System family of products, on which all of the compounds are built.  The resin is a clear, pale amber, low-viscosity liquid epoxy resin.  Formulated for use with West System hardeners, it can be cured in a wide temperature range to form a high-strength solid with excellent moisture resistance.  It is designed specifically to wet out and bond with wood fiber, fiberglass, reinforcing fabrics and a variety of metals.  An excellent adhesive, 105 will fill gaps and bridge voids when modified with West System filler and can be sanded and shaped when cured.  With roller applications, it possesses excellent thin-film characteristics to flow out and self-level without “fisheyeing”.  The resin cures clear so that you can achieve a natural finish when coating with varnish.   It has a relatively high flash point and no strong solvent odor, making it safer to work with than polyesters.
205 Epoxy Hardener
A medium-viscosity epoxy curing agent. It is used in a majority of situations, at lower temperatures and to produce a rapid cure that develops its physical properties quickly at room temperature. When mixed with the 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. Mixing ratio is 5:1.
Potlife at 72° F.: 9 to 12 minutes
Cure to a solid state: 6 to 8 hours
Cure to maximum strength: 1 to 4 days.
Minimum recommended temperature: 40°F

Developed for coating and fiberglass cloth application where an exceptionally clear, moisture-resistant, natural wood finish is desired. 207 Hardener will not blush or turn cloudy in humid conditions. Thin film applications roll out and tip off smoothly, requiring less sanding in preparation for finish coatings.
Three coats or more can be applied in one day without additional surface preparation. Fewer coats are required to fill fiberglass weave and in most cases the final coating can be sandd the following day.
105/207 has strong physical properties, so it can be used as a structural adhesive for gluing and l aminating. It has excellent compatibility with paints and varnishes. An ultraviolet inhibitor in 207 helps provide a beautiful, long lasting finish when used with quality UV filtering varnish. 105/207 cures clear and colorless.

Thickening additive used to control the viscosity of the epoxy and prevent epoxy runoff in vertical and overhead joints. 406 is a very strong filler that creates a smooth mixture, ideal for general bonding and filleting. It is also the most versatile filler in the West System. Often used in combination with other fillers, it can be used to improve strength, abrasion resistance, and consistency of fairing compounds, resulting in a tougher, smoother surface.

A toughened, versatile, liquid epoxy for permanent waterproof bonding of fiberglass, ceramics, metals, plastics, damp and difficult-to-bond woods. With a modulus of elasticity of 150,000 PSI, it is a bit more flexible than standard epoxies and polyester, but much stiffer than adhesive sealants. This gives G/flex the ability to make structural bonds that can absorb the stress of expansion, contraction, shock and vibration. It is ideal for bonding dissimilar materials. It can be modified with West System fillers and additives, and used to wet-out fiberglass tapes and fabrics. Mixed at a 1:1 ratio, G/flex gives you 45 minutes of working time at room temperature. It reaches an initial cure in 7 to 10 hrs and full cure in 24 hrs. 8 oz. kit (2 4 oz. bottles).
