About Cocoon Holland B.V.

“We are a company 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.
