Seals, an aerospace-derived surface protection for ship maintenance

Based on technologies developed for the aerospace industry, the Swiss company seals applies surface treatments based on polymers and nano-diamonds to the marine sector. The aim is to reduce boat maintenance while extending the life of materials exposed to the marine environment.

A boat's surfaces are on the front line when it comes to salt, ultraviolet rays, hydrocarbons and repeated rubbing. Hulls, decks, glazing, stainless steel and textiles age quickly, taking up both time and money. This is where seals, developed by Swiss company traeli ag, offers an approach based on space technology.

A technology born out of boating

Originally, Seals treatments were based on polysilazane phps polymers combined with nano diamonds. These materials were designed to meet the constraints encountered in the aerospace industry, particularly in terms of abrasion, temperature and exposure to radiation. Suitable for marine applications, they form a thin, stable and durable protective layer after application, without altering the appearance of treated surfaces.

Treatments adapted to each material

The Seals range covers all on-board materials. Metals are protected with zeroox. Glazing and transparent surfaces use Pureglas or Cleraglas. Oneshield or Trishield are used for dead works and gelcoat, designed to protect gelcoat and Plexiglas deck surfaces in a single application, with a marked hydrophobic effect and high resistance to grease and ultraviolet rays.


Fabrics, sails and inflatable tenders in hypalon or pvc are treated with Flexix. Engines and hot surfaces are treated with Powerlux. Interiors benefit from Luxint. Packaging is adapted to the surfaces to be treated, from pleasure boats to larger units.

Reduce maintenance

In the boating industry, up to a quarter of a boat's annual costs are routinely spent on maintenance. Seals treatments aim to reduce this burden by limiting the adhesion of marine dirt and contaminants. Treated surfaces can be cleaned more easily, using less water and fewer products.


Applications can be carried out dry, with short polymerization times, which fits in with the constraints of construction sites. Tests have been carried out on boats from manufacturers such as Lagoon, Beneteau and Sanlorenzo, to observe how surfaces behave under operating conditions.

A solution designed for professional use

Seals is aimed at boat owners, boatyards, maintenance companies and marinas, combining professional distribution and end-use. The target market is the marine protection and maintenance segment, which is growing steadily worldwide.
Reducing the use of detergents, water consumption and the frequency of cleaning is in line with current environmental concerns in the boating sector, without changing sailing practices.
