The Smooth-Cast™ 300 Series 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 can be colored with SO-Strong™ or Ignite™ color 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 jewelry.

Those interested in making roto cast pieces should refer to the Smooth-Cast™ 65D technical bulletin.

Features

  • Easy to measure and mix - 1:1 mix ratio by volume - no scale required
  • Low viscosity - captures excellent detail - no degassing necessary
  • Resin cures to a bright white finish

Bright White rocks!

Bright White Polyurethane is one of the easiest resins I've used. I've re-ordered this product a few times, It works without a pressure chamber and is forgiving with measurement. It's great for high detail and stronger than it looks; I once cast flower stems. I've successfully used it with larger casts too.

Be mindful of the shelf life written on the datasheet and be careful not to let condensation get into the bottle.

Great team, can't recommend the product on this occasion

We had supply chain issues with our usual product so got some 310 recently to try to bridge the gap. We got a batch out of the moulds that seemed reasonable. However, then the next batch simply didn't release despite our usual timings, mould release etc. Basically destroyed 6 of our moulds instantly. Subsequent testing it doesnt release without leaving a white film of plastic on the mould or just doesnt release.

This could be just our experience but would recommend testing in small scale first, even if you have used the other 300 series before with no issues (which we have)

The resincraft team are always fantastic.

Excellent Customer service and fast delivery

The Team at Resin Craft have fantastic customer service and deliver at lightening speed. I also approached them a day after I'd purchased as it was Black Friday and they extended the discount to me. 5 *****'s! Would purchase again.

The product came well packaged and in excellent condition.
