Storage & Handling
- Handling and Mixing
LEECAST 16-46 can be mixed de-aired, poured and cured at room temperature. Flexibility is built into the system and different resin to curative ratios can be used. The 1 to 1 mix ratio will provide excellent properties for many applications. More resin relevant to the curative (3 A to 2 B, by weight) will result in a harder, less flexible cured material. Measure out parts A and B and mix thoroughly, scraping the sides and bottom of the container. For void-free castings, de-air under vacuum and cast around components.
The gel time of LEECAST 16-46 depends on the 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:25oC 24 – 48 hours 50oC 4 – 8 hours 80oC 1 – 2 hours 100oC 40 – 60 minutes - Shelf life
6 months
