Pourable Clear Polyurethane Casting Compounds

Polyurethane clear rigid casting compounds are extremely easy to handle, because they have simple mix-ratios and good fluidity. They can be poured into practically any type of mold material with the right release agent (excluding Polysulfides). Certain sensitivities effect them negatively--short shelf life in pre-mixed form and a particularly strong aversion to water. They are available with variable set-up times and can be pigmented for custom work. The listings below are in order of increasing Shore D hardness when cured.

AquaClear
	AquaClear is an optically clear polyurethane used where a hard, UV resistant, non-yellowing product is required. Clear Casting Resin is often used to encapsulate objects. Some of the most common uses of Clear Casting Resins are point-of-purchase displays, rapid prototyping, special effects, sculpture reproductions, giftware, tabletops with embedded items, decorative paper weights, etc. Add color to make colorful translucent art work.

AquaClear is a two-part polyurethane casting system. To preserve the surface clarity of AquaClear, we recommend that you use a platinum-cure silicone mold. To use a condensation-cure (tine-catalyst) silicone mold material you must bake the silicone mold in an over at 200oF for several hours to assure the mold is alcohol free, as alcohol will mar the surface of your AquaClear casting. Though AquaClear will set up with a minimum of embedded air bubbles, if you wish a complete bubble free appearance with use of a pressure chamber is recommended.

Crystal Clear 200 A Smooth-On product designed for applications that require absolute clarity. This product will cure at room temperature, but a 150° post-cure will speed it up. The cured castings are UV stable (non-yellowing) and can be pigmented using color dispersions. Click here for Tech Sheet or MSDS.

Poly 1410 A two-component, water-clear, polyurethane casting system, formulated specifically for applications where optical clarity is a must. The low viscosity and pot life allow easy degassing and handling. Selected dyes and colorants may be added in order to create translucent, colored castings. It is virtually unbreakable and can be cured at room temperature. Best clarity is contingent on vacuum degassing to avoid bubbles.

Clear Flex 50 A perfectly clear flexible material that does not need to be vacuum cast. The super-low viscosity allows easy bubble release. This rubber is actually being used more as a casting material than a mold material, but when used for molds, offers the convenience of being able to see through it for easy cutting. Unfortunately, either a heated post-cure or a week at room temperature is required, so time becomes an issue. Click here for Tech Sheet or MSDS.
