Foamed-In-Place Gasket

Ever wondered about what is meant by "foamed-in-place gasket?"  The robotically applied gasket is a thixotropic, two component modified polyurethane resin system. The gasket’s closed cell design is excellent where very low water absorption is required.  It is evident the type of gasket that is used on an enclosure is very important to the environmental rating of the enclosure. The quality of the application and the sustained durability of Rittal’s foamed-in-place gasket is second to none.

Application of the Foamed-In-Place Gasket is performed following the paint process.  Each enclosure or enclosure skin is brought to a fully automated gasketing machine. This machine applies the gasket, which is a mixture of Polyol and Isocyanate, to the enclosure part with remarkable precision and speed. The gasket is applied in a number of different widths and thicknesses depending upon the specific enclosure. The newly gasketed part now goes to a curing station where it will be safe to touch after 20 minutes and fully cured in two hours.

350 degrees Fahrenheit for up to 30 minutes!

The gasket will return to its original form no matter how long it has been compressed. There are no cracks or seams to allow dust, dirt or liquids into the enclosure. The foamed-in-place gasket will withstand 350°F for a maximum of 30 minutes. The gasket is paintable, which allows the customer to paint the enclosure without masking off the gasket. The gasket will maintain all of its original properties.
