General Description
1,0512;06 Epoxy is used for general coating and bonding applications when extended
working and cure time are needed or to provide adequate working time at higher
temperatures.
lOS1206 forms a high-strength, moisture-resistant solid with excellent bonding and
barrier coating properties. It will wet out and bond to wood fiber, fiberglass, reinforcing
fabrics, foam and other composite materials, and a variety of metals.
t1S1206 Epoxy can be thickened with’WEST SYSTEM fillers to bridge gaps and fill voids
and can be sanded and shaped when cured.
‘With
roller applications, it has excellent thin-
film characteristics, allowing it to flow out and self-level without “fish-eyeing.” Multiple
coats of 1,051206 Eporry ueate a superior moisture barrier and a tough, stable base for
paints and varnishes. It is formulated without volatile solvents resulting in a very low
VOC .o.rt.trt. It has a relatively high flash point, no sffong solvent odor and does not
shrink after curing. It is not intended for clear coating natural finished wood.

To prevent water spotting, avoid contact with moisture until epoxy is thoroughly cured and top coated.

Store PRO-SET Epoxy resins and hardeners at room temperature in sealed containers until shortly before use. As with many high-
performance epoxy resins, repeated exposure to low temperatures during storage may cause the resin to crystallize. If this occurs,
warm the resin to 125 F and stir to dissolve crystals. Hardeners may form carbamation when exposed to CO
2 and moisture in the
atmosphere for extended periods of time. Prevent carbamation by protecting hardeners from exposure until immediately prior to
processing.
Test specimens were neat epoxy (without fiber reinforcement).

General Description
1,0512;06 Epoxy is used for general coating and bonding applications when extended
working and cure time are needed or to provide adequate working time at higher
temperatures.
lOS1206 forms a high-strength, moisture-resistant solid with excellent bonding and
barrier coating properties. It will wet out and bond to wood fiber, fiberglass, reinforcing
fabrics, foam and other composite materials, and a variety of metals.
t1S1206 Epoxy can be thickened with’WEST SYSTEM fillers to bridge gaps and fill voids
and can be sanded and shaped when cured.
‘With
roller applications, it has excellent thin-
film characteristics, allowing it to flow out and self-level without “fish-eyeing.” Multiple
coats of 1,051206 Eporry ueate a superior moisture barrier and a tough, stable base for
paints and varnishes. It is formulated without volatile solvents resulting in a very low
VOC .o.rt.trt. It has a relatively high flash point, no sffong solvent odor and does not
shrink after curing. It is not intended for clear coating natural finished wood.

Store at room temperafure. Keep containers closed to prevent contamination.
rVith
proper storage, resin and hardeners should remain usable for many years’ After a long
storage, verify the metering accvracy of the pumps. Mix a small test batch to assure
proper curing.
Over rime, 105 Resin will thicken slightly and will therefore require extra care when
mixing. Repeated freezelthaw cycles during storage may cause crystallization of 105
Resin.
‘S0arm
resin to 125’F and stir to dissolve crystals. Hardener may darken with age,
but physical properties are not affected by color. Be aware of a possible color shift if very
old and new hardener are used on the same project.
