About Cocoon Holland


We are located in Hoofddorp, a town nearby the airport, and we also have our dedicated storage facilities in Drachten, the north of The Netherlands where we store spare parts of LNG carriers.

Alexander van der Zee, owner of Cocoon (since 2002), has established roots in the painting industry. His grandfather had a paint factory where his father also worked in and so became quite familiar with the production and application of paint-related products from a young age.

When the opportunity came to offer cocoon products, he seized that chance to further develop new applications for the technology.

Reasons to choose for seam and gap sealing by Cocoon

In a valuable building where servers, generators and other important equipment are present, it is essential that rooms are completely sealed or even conditioned.

All seams and cracks must be closed. It is possible to make the seal completely gas-, air- and watertight. Moisture and electronics do not go well together. We understand that. 

Cocoon uses a revolutionary coating product to seal air ducts, cable ducts and pipes in a professional and responsible manner.

The coating is a high-quality, sprayable synthetic material that is also maintenance-free. This product can be connected to electric cables, data cables, air ducts and other materials.
