This vacuum kit is offered to keep 10 different resin components under vacuum in 10 household bottles.
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 crystallize and will lose its warranty.
Not to mention the polyol component which takes up water, moisture from the air. As a result at the later mixing with the isocyanate the mixture will expand like a fome and will be rubbish.
Our casting resin vacuum storage system includes:
- 1 vacuum pump (74 cm3)
- 10 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 of glass jars up to 5 liter .
