The Smooth-Cast® 300 Series (70D) (white) of liquid plastics are ultra-low viscosity casting resins that yield castings that are bright white and virtually bubble-free. Vacuum degassing is not necessary. They offer the convenience of a 1A:1B by volume or 100A:90B by weight mix ratio. The differences between them are pot life and demold time.
These resins readily accept fillers (such as URE-FIL® 3 ) and can be coloured with SO-Strong® or Ignite® colour tints (Smooth-Cast® 325 series accepts pigments better than the Smooth Cast® 300 series). Fully cured castings are tough, durable, machinable and paintable. They resist moisture and mild solvents. Applications for Smooth-Cast® 300 Series Liquid Plastics include reproducing small to medium size sculptures, making prototype models, special effect props and decorative jewellery.
Those interested in making roto cast pieces should refer to the Smooth-Cast® 65D technical bulletin.

The Smooth-Cast® 320Series (70D) (off-white) consists of ultra-low viscosity casting resins that yield virtually bubble-free off-white castings. The Smooth-Cast® 320 resins are sister products to our popular Smooth-Cast® 300 Series of bright white plastics but are easier to colour using SO-Strong® or Ignite® colour tints. Smooth-Cast® 320 series is easy to mix and pour, offering the convenience of a 1A:1B by volume or 100A: 90B by weight mix ratio.
The Smooth-Cast® 320 Series resins readily accept pigments and fillers (such as URE-FIL® 3, 5 and 7 from Smooth-On). Fully cured castings are tough, durable, machinable and paintable. They resist moisture and mild solvents. Applications for Smooth-Cast® 320 Series resins include reproducing small to medium size sculptures, making prototype models, special effect props, decorative jewellery and taxidermy (bones, antlers, teeth etc.).
Smooth-Cast® 320- 3 minute pot life - 10-minute demold time
Smooth-Cast® 321- 9 minute pot life - 30-minute demold time
Smooth-Cast® 322 - 20 minute pot life - 4-hour demold time
The Smooth-Cast™ 325, 326 & 327 (72D) ColorMatch™ Series (Clear amber) plastics are urethane resins that were developed specifically for adding colour pigments and fillers to achieve true colour representation or filler effect. The ColorMatch® Series is formulated as “colour neutral”. Small amounts of pigment will yield accurate, vivid colours from cured castings using So-Strong™ tints UVO™ pigments or Ignite™ colour pigments. The ColorMatch™ Series offers the convenience of a 1A: 1B mix ratio by volume and has a very low viscosity. Demold times range from about 10 minutes to 2-4 hours (depending on product, mass and mould configuration). Note: Large mass castings will get very hot and shrink more, depending on mould configuration.
The ColorMatch™ Series also readily accept fillers (such as URE-FIL™ 3 from Smooth-On). Because of its neutral colour, Smooth-Cast™ 325 is ideal for creating marble and wood grain casting effects or duplicating the look of real metal by adding bronze, brass or other metal powder. Applications for the ColorMatch™ Series plastics include making pigmented prototype models or figures, special effect props, reproducing small to medium size sculptures, decorative jewellery, etc.
Smooth-Cast® 325- 2.5 minute pot life - 10-minute demold time
Smooth-Cast® 326- 9 minute pot life - 1-hour demold time
Smooth-Cast® 327 - 20 minute pot life - 4-hour demold time
The Smooth-Cast® Semi-Rigid (45D, 60D, 61D) line of low-cost semi-rigid urethane casting resins cure quickly to semi-rigid plastics that offer exceptional strength and impact resistance.
Smooth-Cast® Semi-Rigid is newly reformulated with a translucent white appearance and improved physical properties. All Smooth-Cast semi-rigids are now mercury-free and phthalate-free. These plastics are easy-to-use (mix ratio is 1A:1B by volume) and have low viscosities for minimal bubble entrapment. Vibrant colours are possible by adding SO-Strong® colour tints or Ignite® colour pigments.
Suitable for making impact resistance prototypes, abrasion resistant parts, climbing holds, foundry patterns, roller facings, vibration pads, etc.
Smooth-Cast® 57D is a semi-rigid urethane plastic that offers a gradual cure profile (does not snap cure), making it suitable for machine or hand rotational casting.
Use For Rotational Casting - Once poured into a suitable rubber mould configuration, the mould can be rotated so that the resin mixture gradually coats the inside of the mould cavity. After an adequate wall thickness is attained inside the mould, the result is a cured hollow casting that is semi-rigid and highly impact resistant.
Use as a Casting Resin – Smooth-Cast® 57D can also be used as a casting resin for making solid, semi-rigid castings that are tough and durable.
The mix ratio is 1A:1B by volume. Working time is 3 minutes, demold time is 30 minutes and full cure properties are attained after 24 hours. The Colour is white translucent and the material is very easy to colour with SO-Strong®, UVO® or Ignite® colourants. Cured resin is also easy to paint with acrylic paints or UreCoat® flexible coating for applications requiring thick, durable finishes.
