Specialty Plastics Polyurethane Plastic
Simpact® Tough 60A & 85A Urethane
Simpact® 60A & 85A are low odor, fast-setting urethanes that offer very high
tear strength, impact resistance and wear resistance. They are phthalate free,
mercury free and MOCA free. Cured rubbers have exceptional
performance characteristics and dimensional stability.
Simpact® 60A & 85A can be colored with
SO-Strong®, UVO® or Ignite® colorants.
They are suitable for making impact resistant
props, prototypes and display pieces.
Simpact® 60A & 85A are both on the border between being a rubber
and a plastic. This attributes to their toughness and durability, and makes
them a favorite among aquarium customers.
Plasti-Paste® II Plasti-Paste II,
®
Trowelable Plastic Paste Fully Paintable!
Plasti-Paste® II is a low-cost fiber-filled resin that holds a vertical surface
without sagging and cures to a strong, durable and lightweight plastic.
Developed originally as a mother mold material, this plastic can also be used
for creating themed environments or special
effects. Cured plastic can be sanded, machined
and painted with acrylic enamel paints.
Shell Shock® Plasti-Paste® II holds a vertical
surface without sagging for
making lightweight mother molds.
Brushable Liquid Plastic
Shell Shock® FAST and SLOW are thixotropic plastics that self-thicken when
mixed and can be brushed onto a variety of surfaces or into rubber molds.
Material cures at room temperature with minimum shrinkage to a hard,
durable plastic. Fully cured castings are rigid and can be sanded, primed
and painted. Shell Shock® is ideal for making fast, lightweight rigid
molds for creating silicone appliances and effects.
Shell Shock® rigid molds are used to
create film-quality silicone masks.
