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.

105 Epoxy Resin® is the base material on which all West System 105 System
epoxy compounds are built. The resin is a clear, pale yellow, 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.
105 Resin is formulated without volatile solvents and does not shrink after
curing. It has a relatively high flash point and no strong solvent odor, making
it safer to work with than polyester or vinylester resins. Resin viscosity is
approximately 1000 centipoise (cp) at 72 F (22C),
105 Resin is designed
specifically to wet out and bond with wood fiber, fiberglass, reinforcing
fabrics and a variety of metals when mixed at the proper ratio with a West
System hardener. An excellent adhesive, 105 mixtures will bridge gaps and fill
voids when modified with West System fillers and 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 resin and hardeners are sold in matched sets according to the
letters A, B and C. An "A" Kit (resin plus hardener) is 1 quart, "B" is 1 Gallon
and "C" is 5 Gallon. Each part must be purchased seperately, however make sure
you order both parts (hardener and resin) in the same size A, B or C.
These convenient kits are pre-packaged with West System 105 resin, 205/206
hardener and pumps included. Choose your size A/Quart or B/Gallon and the
hardener you need 205 Fast or 206 Slow.
205 Fast Hardener® is 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. Not intended for clear
coating. Pot Life at 72F (22C): 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 (4°C)

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.
Pot life at 72°F (22°C): 20 to 25 minutes Cure to
a solid state: 10 to 15 hours Cure to maximum

207 Special Clear Hardener™ was 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.
Professional and first-time builders like 207 because it is reliable and easy
to use. 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. Boats can be built faster.
Builders also appreciate the excellent fiberglass wet-out characteristics
achieved with 105/207, yet it won't drain from vertical surfaces like the very
slow curing, low-viscosity epoxies.
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.

This strong, wood-toned filler is good for use in glue joints and fillets on
naturally finished wood. It mixes easily with epoxy and lets you create fillets
that are smooth and require little sanding. Its color is a consistent brown, so
405 can be used to modify the shade of other WEST SYSTEM fillers.
406 Colloidal Silica is a 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 our most versatile filler. 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.

WEST SYSTEM pigments are epoxy-based liquid colorants used to tint the epoxy
mixture to provide an even color base for the final finish system. The colored
surfaces also tend to highlight flaws and imperfections. Cured, pigmented epoxy
surfaces are not a final finish surface, but require an additional opaque or UV
filter coating for ultraviolet protection. Add to the mixed resin/hardener at a
rate of approximately one teaspoon of pigment to 8 fl oz of epoxy. More pigment
will increase opaqueness and mixture viscosity. One 4 fl oz bottle will tint
approximately 2/3 gal of epoxy.
Available in white or gray. 4 oz containers.

Woven fabric tapes are electrical grade fiberglass that come in
various widths: 729 (2"), 731 (3"), 732 (4”) and 733 (6"). They weigh
9 oz per square yard. These woven tapes have a selvaged edge that
prevents fraying. Tapes are ideal to toughen and protect corners as
well as for a myriad of other applications.
Available in 2", 3", 4" and 6" widths. 10' long or 50' long.

727 Biaxial Tape is 4" wide, 15 oz (per square yard) electrical grade
fiberglass referred to as E glass. Biaxial is essentially two layers
of unidirectional fiberglass placed 45° to the ‘0’ axis off the roll.
The layers are held together with a light stitching, thus it is
referred to as a stitched tape. It should not be confused with braid,
which is woven. Biaxial has good utility as the strands are
oriented to allow the tape to pass over a tighter corner. Biaxial is
generally stronger on a per thickness basis than a woven fabric. 727
is .018" per tow in thickness and has a specific gravity of 2.54.
Woven tape has half its fibers taking the full brunt of the bend
whereas with biaxial they pass as a more gradual 45° angle.
However, Biaxial materials will take more filling with resin or
fillers to finish smooth.
Comes in 2 pack sizes: 4" x 10' and 4" x 20 yards

702 and 703 Unidirectional Carbon Tapes are designed to be used
with WEST SYSTEM Brand epoxy. The hardener choice is dependent
on laminate thickness (dimensionally), the time required to perform
the operation, and ambient temperature when cure will take place.
702 and 703 carbon fibers are in tow form. A tow is like a
ribbon. The tow of this material consists of 12,000 fiber bundles per
inch of width, so it is referred to as 12K material. The tow is
continuous, and unidirectional on the ‘0’ axis (along the tow length).
The fibers are not twisted or woven. The white strands running on the
90 (degree) axis are polyester threads that hold the fiber bundles in
place and are non-structural. This 12K material is on the order of 11
oz (per square yard) material and measures .025" thick. Carbon fibers
are electrically conductive and have a specific gravity of 1.75.
Available in 4 sizes. 1 1/2" and 3" wide. 12' and 50' long
