  • Best Practices for Elantas (Altana) 1817

    *See Terms of Use Below

    1. Surface Preparation

      It is important that all dirt, rust, grease, and oil be removed from surfaces prior to applying the primer. Request Surface Preparation Guide, Bulletin AC-107, for recommendations.

    2. Mixing

      CONATHANE TU-8090 can be processed by batch mixing or by the use of automatic metering, mixing, and dispensing equipment. Specific recommendations can be made by the technical service department of Cytec Industries Inc. or by your regional sales manager. The following procedure is recommended for batch processing: Containers used for weighing or mixing should be metal, glass, or plastic. Mixing rods should also be metal, 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 two to three times the volume of material being mixed) if voidfree 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 vacuum to remove air entrapped during mixing.

      Pour mixed material into molds or fixtures in a manner to avoid trapping air bubbles or pockets, and cure as recommended. Porous molds should be properly sealed prior to using. Contact Cytec's customer service department, or your local regional sales manager, for assistance.

      If parts are to be demolded, a quality CONAP® mold release should be applied prior to pouring.

    3. Clean-Up

      Equipment may be cleaned with methylene chloride or acetone.
