Applications Clear Casting Resin is an optically clear polyurethane casting resin 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 Resin are point-of-purchase displays, rapid prototypes, special effects, sculpture reproductions, giftware, etc. Characteristics Clear Casting Resin is a two-part polyurethane casting system. Clear Casting Resin is mixed one-to-one by volume and cures at room temperature. Cured Clear Casting Resin is UV resistant and non-yellowing. To preserve the surface clarity of Clear Casting Resin, we recommend that you use a platinum-cure or condensation-cure silicone mold material such as LifeRite.   Clear Casting Resin provides a combination of performance properties including optical clarity, mechanical		Portrait Of  a Young Woman by Dave Parvin, A.L.I.  Created with Clear Casting Resin and  LifeRite Silicone Mold The piece was sand blasted on the surface to  provide a semi-transparent optical texture.  The rear of the piece was left window-pane  clear. An strange optical illusion is produced  when the piece is rotated in front of the viewer.  When viewed from the rear it appears that the  young girl's face is projected outwards as if in a hologram.

Using two clean, dry, plastic containers of equal size, measure equal amounts of the curative (part A) and the pre-polymer (part B). Do not measure more Clear Casting Resin than you can pour within its 15 minute pot life.   Mix Curative and Pre-polymer Note: Once you mix the curative and pr-epolymer, you have approximately 15 minutes to pour the casting. After you prepare the mold and measure the curative and pre-polymer, you are ready to pour the curative and pre-polymer into another clean, dry, plastic container. Combine the two ingredients for approximately 45 seconds, being careful to prevent air bubbles from forming. Use a plastic or metal utensil to mix Clear Casting Resin. You can use a vacuum chamber to help remove any air bubbles that form during mixing.   Pour Casting You should take your time to carefully pour it into the mold. The best way to pour a casting with Clear Casting Resin is to tilt your mold slightly and pour into one spot of the mold. Pour slowly so that any air bubbles that may have formed during mixing can break over the lip of the container as it pours out. When you have finished pouring your casting, you may tap the sides of the mold or vibrate the mold to help release additional air bubbles.   Demold and Cure Casting Once you have poured your casting, do not disturb the mold or demold the casting for 24 hours. Although you may work with your cast immediately after demolding, for best results we strongly recommend that you post cure your cast for 6 hours at 160°F (72°C).  The post cure improves the heat distortion temperature as well as numerous other properties of the material.   Properties Curative (Part A) and Pre-polymer (Part B ) The following table explains the properties of the curative and pre-polymer of  Clear Casting Resin before they have been mixed.

Do not expose the Clear Casting Resin curative or pre-polymer to moisture! If moisture contaminates Clear Casting Resin, it will not cure. If these storage requirements are met, Clear Casting Resin carries a shelf life warranty of six months. Be sure to read the Material Safety Data Sheet that comes with Clear Casting Resin before using it. As with any polyurethane, observe the following safety precautions. ·     Use only in well-ventilated areas. ·     Wear chemically resistant rubber gloves, safety glasses, and an apron. ·     Avoid prolonged or repeated contact with skin. ·     In case of skin contact, wipe affected area with isopropyl alcohol,  followed by soap and water. ·     In case of eye contact, flush eyes with water for 15 minutes and  consult a physician. ·     If swallowed or comes into contact with eyes, seek medical attention immediately
