BP4122
BP 4122 is a fast-set, high-temperature, aluminum-filled epoxy casting resin. It will cure
rigid overnight but requires a post-cure to achieve optimum properties. The filler in the
resin will not settle into a hard-pack even after prolonged standing. BP 4122 is formulated
to have minimum skin irritation potential and avoids all carcinogenic materials in both
the resin and hardener.
Features:
Mix ratio(by wt.): 100:9.5
Viscosity (mixed): 26,500cps
Pot life (hrs): 2
*Cure time (hrs)(72°F): 16
Hardness (shore): 82D
Heat Deflection (°F):315
Color: Gray
Datasheet
*note: different cure schedule in the case of high temp tools

BP4123
BP 4123 is a medium-set time, high-temperature, aluminum-filled epoxy casting resin. It will cure
rigid overnight but requires a post-cure to achieve optimum properties. The filler in the resin
will not settle into a hard-pack even after prolonged standing. BP 4123 is formulated to have
minimum skin irritation potential and avoids all carcinogenic materials in both the resin
and hardener.
Features:
Mix ratio(by wt.): 100:8
Viscosity (mixed): 23,750cps
Pot life (hrs): 3
*Cure time (hrs)(72°F): 16
Hardness (shore): 82D
Heat Deflection (°F):300
Color: Gray

BP4124
BP 4124 is a slow-set, high-temperature, aluminum-filled epoxy casting resin. It will cure rigid
overnight but requires a post-cure to achieve optimum properties. The filler in the resin will
not settle into a hard-pack even after prolonged standing. BP 4124 is formulated to have minimum
skin irritation potential and avoids all carcinogenic materials in both the resin and hardener.
Features:
Mix ratio(by wt.): 100:7
Viscosity (mixed): 11,250cps
Pot life (hrs): 5
*Cure time (hrs)(72°F): 16
Hardness (shore): 85D
Heat Deflection (°F):280
Color: Gray

BP9024
The 5-minute Epoxy Adhesive
BP 9024 is a fast-set epoxy adhesive specially formulated for the bonding of wood and urethane
model board. It can also be used for making quick patches and fast laminates. The resin is color
indicated (green) and will turn to a clear amber color as the hardener is mixed into the resin.
This indicator system promotes fast and efficient mixing of the resin and hardener, insuring
that they are thoroughly mixed, yet wasting no time overmixing.
Features:
Mix ratio(by wt.): 100:100
Viscosity (mixed): See datasheet
Pot life (min): 5
Set time (min)(72°F): 15
Hardness (shore): 60D
Color: Lt Amber
