This vacuum kit is offered to keep four different resin components under vacuum in 4 household bottles or jars.
That’s very useful if you do not use up the resins within a short time after opening the original packaging. Otherwise, especially the isocyanate tends to crystallise and will lose its warranty.
Not to mention the polyol component, which takes up water, and moisture from the air. As a result, after mixing with the isocyanate, the mixture will expand to be rubbish.
Our casting resin vacuum storage system includes:
- 1 vacuum pump (74 cm3)
- four pc. vacuum stopper
The valve of the vacuum stoppers can be separated so that they can be used not only for wine bottles but also for vacuuming glass jars up to 5 litres.
