  • Best Practices for Elantas (Altana) UC-40

    *See Terms of Use Below

    1. Application

      When casting, pour in a steady stream in one spot at a rate that avoids overlapping or enfolding air. To improve flowability, preheat parts to be cast to 50-60ºC (120-140ºF). CAUTION: Work life of material will decrease.

      Some urethane prepolymers or hardeners may freeze or crystallize below 18ºC(65ºf). They may be re-liquefied by heating to 50-60ºC (120-140ºF). Avoid prolonged preheating. After heating, blend thoroughly.

      If parts are to be demolded, a quality mold release, such as CONAP® MR-5002 or MR-5012 should be applied prior to pouring.

      CONATHANE® UC-40 has very good adhesion to most substrates and generally will not require the use of a primer. If adhesion improvement is necessary, contact Cytec for specific recommendations. If the cast part is to be demolded after cure, apply a CONAP® mold release agent prior to casting. Castings can generally be demolded in 6 hours at room temperature.

    2. Mixing

      Maintain mixing ratio accuracy between Part A and Part B to within ±2% using a double-pan or triple-beam balance. Avoid spring-loaded scales.

      Containers used for weighing or mixing should be metal, glass, or plastic. Mixing rods should also be plastic or glass. Avoid paper containers and wooden sticks!

      Use a separate container for mixing, with enough space to allow for expansion during degassing (usually 2 to 3 times the volume of material being mixed), if void-free castings are desired. In many applications, the degassing step may be eliminated.

      Weigh the correct proportions of the two components together, MIX THOROUGHLY, and degas at 28-29 inches of mercury to remove entrapped air caused by mixing.

    3. Clean-Up

      Equipment may be cleaned with Methyl Ethyl Ketone
