Evaporating Wax (cyclododecane) - Wax-like material that evaporates without melting

This material sublimates (turns directly from a solid to a gas) at room temperature. It disappears completely without leaving any residue.

Used for:

It is used in archaeology, restoration, and conservation for temporary fixation and support of weak and fragile materials such as paper, textile, canvas, and ceramic. Conservators also use it as a sealant, water-repellent barrier, coating, gap filler, and separation layer. It is usually applied as a melt (melting point is ~65°C) but it can also be dissolved in, for example, isooctane or naphthas and then applied.

Details:

The wax adheres on most surfaces when melted or dissolved; a film of 1 mm needs about 30 days to totally evaporate, whereas a sprayed film evaporates faster. It is hydrophobic but can be removed with petroleum spirit. It is believed to be non-toxic.

Idea:

Create a time-dependent self-opening seal or valve. The sprayed variant is white in appearance and could be used at Christmas as artificial snow spray for windows.

The sample:

You get a small container with around 10 grams of wax as seen on the product photo.

All samples come with a laminated information card, which includes contact details for the supplier.
