Smooth-Cast® General Purpose Casting Resins
semi-rigid resins Smooth-Cast Semi-Rigid Resins
are available
in different Smooth-Cast® 45D, 60D, 61D, 65D and 66D
hardnesses. are low-cost urethane casting
resins that cure quickly
to semi-rigid plastics
that offer excellent impact
resistance. These plastics
are easy to use (mix ratio
is 1A:1B by volume) and
have low viscosities for
minimal bubble entrapment.
Vibrant colors are possible by adding SO-Strong®, UVO® or Ignite® colorants. Smooth-Cast® 60D
These semi-rigid plastics will really take a beating and offer exceptional abrasion can really take
resistance. They are good for making high-impact resistance tools, prototypes, etc. a beating!

is unique among the
semi-rigid resins. It has
a gradual cure profile
making it ideal for
rotational casting
applications. It can
be cast hollow or
filled with foam
for lightweight
Smooth-Cast® reinforcement.
