- Handling and Mixing
LEECAST 29-192-1 can be mixed, de-aired, poured and cured at room temperature. Measure out Part A and B and mix thoroughly, scraping the sides and bottom of the container. The final mixed color is white. For void-free castings, de-air under vacuum and cast around components. The gel time of LEECAST 29-192-1 depends on temperature and mass of material. Large masses and/or elevated temperatures will shorten the gel time. Cure can be accomplished at room temperature or with heat if faster cures are desired. Typical cure schedules for small masses are: 50oC 4 – 8 hours 80oC 1 – 2 hours
