| Crystal Clear® 220 & 221 are water white clear resins made specifically for applications that require absolute clarity. These are"heat cure" systems and are harder versions of our popular Crystal Clear® Series resins (Shore 85D). Cured castings are UV Resistant (resists yellowing due to ultra-violet light exposure) 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, special effects and props. |
