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.

Crystal Clear 200, 202, 204 and 206 are water white clear and made specifically for applications that require clarity. These rigid urethane casting resins differ only in working and demold times. Low viscosity ensures easy mixing and pouring. Crystal Clear resins cure at room temperature* with negligible shrinkage. Cured castings are UV Resistant and are not brittle.

Vibrant colors and color effects are achieved by adding pigment dispersions. Applications include encapsulation, making prototype models, lenses, sculpture reproductions, decorative cast pieces, jewelry, prototype models, special effects and props.

* Casting Thickness & Cure Time - The cure time and ultimate shrinkage of all Crystal Clear products will vary depending on mass concentration, thickness of the casting, mold configuration, etc. For example, a 200 gram mass of CC 200 will cure faster if left to cure in a conical vessel (cup) versus a casting dispersed as a thin sheet measuring 3 centimeters square by 1 mm thick. This is due to the heat generated by the concentration of material in the cup versus heat that is dissipated from the sheet casting. Castings will resist yellowing when exposed to UV, but may darken over time.

• Crystal Clear® 200 is intended for a casting thickness ranging from 1/2in to 3in at a casting weight maximum of 16 lbs. (7.25 kgs.) Castings greater than 3in should be layer cast.
• Crystal Clear® 202 is intended for casting in thin sections. Developed for casting thicknesses of no more than 1/2in.
• Crystal Clear® 204 can be cast in thicknesses up to 6in at a casting weight maximum of 35 lbs. (15.88 kgs.).
• Crystal Clear® 206 is for castings greater than 6in.

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.
