Multi-Purpose Urethane Casting Resins

SC-300 Series * SC-320 Series * SC-Colormatch™ Series

The Smooth-On family of multi-purpose urethane casting resins offers the user tremendous versatility and economy. These products feature the convenience of a one-to-one mix ratio by volume -- no scale is necessary. Very low viscosity ensures easy mixing, pouring and exact duplication of detail. These urethane resins cure with negligible shrinkage to hard plastics that are tough, durable, machinable and paintable. They also resist moisture and mild solvents. Vibrant color and color effects are easily achieved by adding pigments.

Applications:

Prototype Models/Parts
Plastic Mechanical Parts
Sculpture Reproductions
Architectural Models
Artistic Creations
Durable Miniatures & Toys
Special Effects
Theater Props
Cold Cast Bronze (Bonded Metal) Castings

SC-300, SC-305 and SC-310 - the lowest viscosity of any casting resins available. They literally pour like water and yield castings that are bright white and virtually bubble-free. They have no odor and contain no solvents (low shrinkage factor). SC-300 is ideal for making fast castings and can be consistently foamed. SC-310 has a 20 min. pot life for applications requiring a longer cycle time.

SC-320, SC-321 and SC-322 - lower cost version of SC 300 Series. Off-white in color.

Epoxy Casting Compounds

Smooth-On Epoxy Casting Compounds are suitable for a variety of industrial applications. Epoxy Compounds are harder than our urethane plastics and offer superior resistance to impact, abrasion and heat distortion. They are also widely used for electrical encapsulation & bonding applications. Consult technical bulletins for complete details. Most of the epoxies can be used with the fast, medium or slow catalyst.
EpoxAcast 650 is a mineral filled general purpose epoxy. It can be used for dies, metal stamping, patterns and electronic encapsulation.

EpoxAcast 655 (was A-30) Aluminum Filled - Non-settling, low viscosity with low overall shrinkage.
It is used in making vacuum forming dies, injection molds, and foundry patterns.

EpoxAcast 670 HT (was 20-136 HT) Mineral Filled - Superior heat resistance, low viscosity, readily degasses itself. Can be used as a high temperature epoxy adhesive (resists temperatures up to 350 F / 177 C).

EpoxAcast 690 Clear casting epoxy is ideal for making jewelry or lenses for car kits.

Applications:

  • Vacuum Form Molds
  • Forming Dies
  • Foundry Patterns
  • Fixtures
  • Industrial Gears
  • Hard Rollers
  • Encapsulation
  • Base Pads
  • Core Box Liners
  • High Impact Models/Special Effects Props
  • Tracing Patterns For Pantagraph And Deckel Modeling Machines

C-1509- Has some flexibility, is strong and very tough.  Originally developed for high inpact tooling (Drop Hammer Punch).  C-1509 also offers good abrasion and chemical resistance.  This product is suitable for some FDA/USDA applications (Dry Food Contact Only).

C-1515- A soft semi-rigid plastic that offers a fast cure ans demold time.  C-1515 is flexible enough to be used as fast setting mold material or for quick model duplication .  Cured casting exhibits good heat and chemical resistance.

C-1520- Is essentially the same material as C-1515, but offers a longer pot life and demold time.

45D, 60D, & 61D- Are Semi-Rigid urethane cating resins that cure quickly and offer excellent impact resistance. These plastics are easy to use and have low viscosities for minimal bubble entrapment.  Vibrant color are also possible by adding So-Strong color tints.  These semi-rigid plastics are virtually unbreakable and offer exceptional abrasion resistance.

Applications:

Fast Mold Impressions
Abrasion Resistant Liner
Vibration Dampening Pads
Machinery Base Pads/ Gears
Fast Cast Models
High Impact Tooling
Cutting Table Tops
Metal Bonding/ Coating
Roller Facing
Fast Concrete Stamping Pad
Foundry Patterns
