COELAN Boat Coating Shelf Life

COELAN® Boat Coating has an excellent shelf life. On each tin, the minimum shelf life date is indicated. The minimum shelf life stamp indicates the manufacturer’s guarantee of how long the product can be stored. However, it does not mean that the product will expire when this date is exceeded. The COELAN Boat Coating is manufactured at frequent intervals allowing the longest storage time.

COELAN Boat coating tin shall not be opened before the preparation of the surface has been completed and the thinner application and curing is completed according to the COELAN guidelines.

COELAN is a polyurethane based coating and reacts with oxygen and humidity. Once a tin is opened, oxygen and humidity is getting in contact with the content. Therefore, it is always recommended to finish a complete tin and not to interrupt the application process. When a tin is initially closed, a vacuum is created to avoid any reaction with oxygen and humidity and to guarantee a long shelf life. COELAN recommends finishing an opened tin rather than to close and store it.

If an application is interrupted or if the project requirements do not make it possible to finish a whole tin, than a tin should be closed carefully. But because the coating has been in contact with oxygen and humidity already, only a shortened shelf life can be expected. The use of BLOXYGEN Leftover Preserver may be a solution if a tin has to be closed. BLOXYGEN is a coating preservative that allows the storing of leftover coating and paint. BLOXYGENis an inert gas that is heavier than air and sinks down to block oxygen from the liquid surface. BLOXYGEN, will separate the liquid surface from any air that may remain in the container.

While some countries require the production date, others require the maximum expiration date and still others show the minimum shelf life. A reference to the date is usually shown on the product label.
